For light mildew stains, spray Slimy Grimy directly onto the seat and let it sit for a few minutes. In most cases, that lifts the stain with nothing more than a gentle wipe. Mildew that has been there a long time may not come out completely, even after repeated applications.
On stubborn spots, mix Slimy Grimy with baking soda to form a paste that adds a bit of grit. Colored vinyl may lighten slightly, much as it does after seasons of sun exposure. Test an inconspicuous area first to see how your seats react.
Yes, Slimy Grimy is an effective boat cushion cleaner for vinyl upholstery. Spray it directly onto the cushion, allow a few minutes of dwell time, then gently scrub the surface with a soft brush. Wipe the cushion or rinse it clean, and then let it dry fully before use again.
Dirt, grime, algae stains, and mildew stains all lift away from many vinyl boat cushions with this routine. Colored vinyl may lighten slightly, so test a hidden seam or underside first. Regular cleaning through the season keeps buildup light and makes each session quicker.
Algae stains on boat hulls come off with Slimy Grimy, which cuts through the marine growth residue left behind on fiberglass and gelcoat. Wet the hull, apply Slimy Grimy, and allow several minutes of dwell time. Then scrub gently with a soft brush or pad and rinse it thoroughly afterward.
For heavier algae staining below the waterline, mix the Granular formula into a paste for extra scrubbing power. Work in sections so the product never dries on the hull. Painted or gelcoat surfaces vary, so test an inconspicuous area before treating the whole boat.
Yes. Slimy Grimy removes the rust-colored stains that iron-rich well water leaves behind on toilets, showers, bathtubs, sinks, and fiberglass shower surrounds. Apply it directly to the stained surface and let it dwell for several minutes. Then scrub with a brush or sponge and rinse thoroughly with clean water afterward.
Heavier staining may need a repeat application, especially around drains and faucets where iron builds up fastest. Homes on well water tend to see these stains return over time. A quick cleaning every few weeks keeps them from setting in.
Fiberglass hulls clean up with Slimy Grimy, which handles waterline stains, algae and mildew stains, marine growth residue, dirt, and grime. Wet the surface first, then apply the product and allow a few minutes of dwell time. Scrub with a soft brush or pad, then rinse thoroughly with clean water.
Colored gelcoat deserves a quick test in an inconspicuous area before you clean the whole hull. Working from the bottom up with a pump sprayer gives even coverage on larger boats. Once the hull is clean and dry, it is ready for waxing.
Boat waterline stain removal is one of the most common reasons boat owners reach for Slimy Grimy. That band typically collects the heaviest marine growth residue and buildup. Wet the area, apply Slimy Grimy along the stained band, and let it dwell for several minutes before you scrub and rinse.
For a stubborn, built-up waterline ring, mix the Granular formula into a paste for extra scrubbing power. A second pass may be needed after a long season in the water. Cleaning the waterline more often keeps the ring from darkening.
Yes, Slimy Grimy can be used while your boat is still in the water, but results won’t be as thorough as cleaning it out of the water. You’re limited to what you can reach at or above the waterline, and the product rinses away much faster in a wet environment.
For routine touch-ups, apply Slimy Grimy, let it dwell a minute or two, then scrub and rinse. Heavy staining or a full bottom cleaning calls for hauling out or using a trailer. Slimy Grimy is phosphate-free, so it won’t harm fish or flora.
Slimy Grimy doubles as a teak cleaner for boats and for outdoor furniture. Wet the teak first, apply Slimy Grimy, and then let it dwell for several minutes. Scrub with the grain using a soft-to-medium brush, then rinse thoroughly so no product is left sitting in the wood grain afterward.
It helps remove the dirt, grime, algae, mildew, and weather-related buildup that turns teak gray. For heavily weathered teak, mix the Granular formula into a paste for extra scrubbing power. Let the wood dry completely before applying any teak oil or sealer.
Wood fences clean up well with Slimy Grimy Granular, especially over larger fence areas. Mix the Granular formula with water in a pump sprayer and apply it, working from the bottom up. That order helps prevent streaking as the solution runs back down over the boards you have already wetted.
Let it dwell for several minutes, scrub any stubborn patches, then rinse thoroughly. Dirt, algae, mildew, mold stains, and other organic soils lift away from most wood fencing. Work in manageable sections so the solution stays wet until you rinse it off.
Slimy Grimy works well as a vinyl and aluminum siding cleaner for house siding. For a whole house, mix the Granular formula in a pump sprayer and work from the bottom up. Let it dwell for several minutes, then brush or sponge the surface and rinse it off thoroughly afterward.
It lifts dirt, grime, algae and mildew stains, oxidation residue, and the rust streaks that sprinkler water leaves behind. Siding colors and finishes vary, so test an inconspicuous area first. Cleaning in the shade keeps the solution from drying too fast.
Barnacles need to be scraped off mechanically first, since Slimy Grimy is made for stains rather than shells. Use a plastic scraper held at a low angle to avoid gouging the gelcoat underneath. Once the shells are gone, rings and surface residue are usually left behind on the hull itself.
Slimy Grimy works as a boat hull stain remover for those leftover marks, marine growth residue, and surface buildup. Apply it, let it dwell for several minutes, then scrub and rinse. Stubborn rings may need a paste of the Granular formula.
Yes, some customers use Slimy Grimy to pre-treat heavily soiled garments, and it can also help whiten laundry. About half a cup added to the soak cycle helps restore white towels and clothing. This works well in areas where iron content in the water causes heavy rust-colored staining over time.
Slimy Grimy may lighten fabrics or dyes, so test a hidden spot on colored items first. Never allow it to dry on fabric, and run a full rinse afterward. For grease, ink, or food stains, Greasy Grime is the better pre-treatment choice.
Many washable fabrics take Slimy Grimy well, including marine canvas and most other outdoor boat fabrics. It helps clean mildew stains, dirt, grime, and other common soils that build up on covers, biminis, and cushions. Apply it to the stained area and allow a few minutes of dwell time first.
Gently scrub with a soft brush, then rinse thoroughly and let the fabric air dry. Test a hidden spot first, since some dyes may lighten. Never let the product dry on fabric, and rinse any spills on nearby surfaces right away.
Slimy Grimy is suitable for many rubber surfaces, including inflatable dinghies, inflatable boats, bumpers and rubber fenders. Apply the product, allow a short dwell time, then gently scrub the surface with a soft brush. Rinse thoroughly with clean water so no residue is left sitting on the rubber surface afterward.
Stiff bristles can scuff rubber, so skip them here and stick with soft brushes or sponges. Dirt, grime, algae stains and mildew stains lift away from most rubber gear. Test a small area first, since rubber compounds vary between manufacturers.
Choosing between Slimy Grimy Granular and Liquid/Spray comes down to the size and type of job in front of you. Both use the same core formula. Spray works best for hulls, seats, fiberglass, well water stains, and routine boat cleaning, since it already comes premixed and is ready to use.
Granular is better for heavy stains, teak, wood fences, concrete, and larger outdoor jobs. One container makes several gallons, which makes it the more economical choice. Granules can also be mixed into a paste for extra scrubbing power on built-up stains.
A 1 lb. container of Slimy Grimy Granular makes up to 3 gallons of solution, which is enough to clean a 20 to 24 foot boat twice over. Mix it with water in a 1-, 2-, or 3-gallon pump sprayer, following the mixing ratio printed on the label itself.
Actual coverage depends on how heavy the staining is and how much surface you treat. A lightly stained hull goes further than one with a full season of buildup. For quick spot jobs, a 32 oz. spray bottle needs no mixing at all.
Slimy Grimy can be mixed with either hot or cold water. Many customers find that hot water speeds up boat cleaning and cuts down on scrubbing time, especially on heavier staining. A warm solution can help loosen built-up grime much faster, which may shorten the dwell time on tough spots.
Whatever the water temperature, follow the mixing ratio on the label. Cold water still works well for routine cleaning and light staining. On hot, sunny days, cooler water can also help keep the solution from drying on the surface before you rinse.
Letting Slimy Grimy dwell on the surface does most of the work, though light scrubbing is typically still needed to fully lift stains and buildup. That trade-off is what lets the formula skip the caustic chemicals found in harsher bottom cleaners. A soft brush or pad is usually enough here.
For older, tougher staining, a longer dwell time and a little more scrubbing will get the best results. Mixing the Granular formula into a paste adds grit where you need it. Just keep the surface wet and rinse before the product dries.
Slimy Grimy is effective on heavy, long-term seasonal buildup. A boat that has sat in the water for months may need a second application or a bit more scrubbing on the worst spots. That is especially true right at the waterline, where marine growth residue tends to collect the heaviest.
For heavy seasonal buildup, mix the Granular formula into a paste for extra scrubbing power. Give the product a longer dwell time on the darkest stains, keeping the surface wet throughout. Cleaning at haul-out keeps stains from setting in over winter storage.
Acid-based hull cleaners can cut through heavy buildup faster, but they’re caustic. They call for heavy-duty protective gear, can burn skin, and can damage paint, clothing, and galvanized trailers if they are not handled carefully. Spills and overspray can also be hard to control on windy days at the ramp.
Slimy Grimy trades some speed for being safer to use, with no acid burns and no heavy PPE required. It’s also gentler on paint and metal when rinsed off before it dries. Expect a bit more dwell time and scrubbing to reach the same result.
Slimy Grimy can be effective even on stains that have been sitting for a long time. Some customers have had success on staining that was neglected for a year or more. Results depend on the surface, the source of the stain, and how deeply it has set into the material.
Older, deeper-set stains may need a longer dwell time, a repeat application, or the Granular formula mixed into a paste. Work patiently in small sections and keep the surface wet throughout. Some very old marks may lighten rather than disappear completely.
No, Slimy Grimy won’t permanently damage asphalt. If it is allowed to dry on the surface, though, it may temporarily lighten or change the appearance of the driveway. That discoloration typically fades and washes away on its own after a few rains, leaving the asphalt looking like it did before.
To avoid it altogether, wet the driveway first and keep it wet while you work. Clean in sections and rinse thoroughly before the product can dry. This is worth remembering when you wash a boat or RV on the driveway, where runoff pools.
Yes, with a few precautions. If Slimy Grimy sits and dries on galvanized metal, it can leave a lasting mark or dull the surface. That damage isn’t easy to undo, so prevention is the whole game here. A hose and a little attention up front keep the trailer safe throughout.
Wet the trailer down before you start and keep it wet while you clean the hull. Keep a hose handy for drips that land on the frame or bunks. Rinse the trailer thoroughly right after cleaning so no product sits on the galvanized finish.
Non-skid decks clean up well with Slimy Grimy as a deck cleaner. Wet the deck, apply Slimy Grimy, and let it dwell for several minutes so it can work into the textured surface. Dirt settles deep in that pattern, so dwell time does much of the hard work for you.
A stiff-bristled brush helps lift dirt, grime, algae, and mildew out of the non-skid texture. Rinse thoroughly afterward so no residue stays behind in the grooves. Regular cleaning keeps the deck looking fresh and stops the pattern from filling with grime.
Yes. Slimy Grimy cleans dirt, grime, algae stains, and mildew stains from live wells, fish boxes, and storage compartments. Apply it to the surface, let it dwell for a few minutes, then scrub with a brush suited to the space. Corners and drain areas need the most attention during cleaning.
Rinse thoroughly with clean water when you finish. Rinsing is especially important in live wells and fish boxes, since all residue needs to be gone before the compartment holds water or fish again. Leave hatches open afterward so the compartments dry out fully.
Yes. Apply Slimy Grimy to the painted surface, allow a few minutes of dwell time, then gently scrub the area with a soft brush or sponge. Rinse thoroughly so that no residue is left sitting on the paint. Working in small sections makes it much easier to rinse promptly afterward.
Painted surfaces vary widely in age, type, and condition, so test an inconspicuous area first. Avoid letting the product dry on the paint at any point during cleaning. Older or chalky paint deserves extra care and a lighter touch with the brush.
Aluminum boat owners have long trusted Slimy Grimy for dirt, stains, and light oxidation residue. Wet the hull, apply Slimy Grimy, and then let it dwell for several minutes. Scrub with a soft brush or pad, then rinse thoroughly to prevent spotting as the aluminum begins drying in the sun.
For heavy oxidation, black streaks or dull aluminum that needs brightening, step up to Blazin’ Industrial Cleaner. It is the stronger product in the line and can etch, so test a small area first. Always rinse aluminum well, whichever product you use.
Yes, Slimy Grimy works well as a pontoon boat cleaner for both aluminum and fiberglass pontoons. Wet the pontoons, apply Slimy Grimy, and allow a few minutes of dwell time. Then scrub the tubes and rinse thoroughly to remove dirt, grime, algae, mildew, and waterline stains from the pontoons themselves.
A pump sprayer makes quick work of long pontoon tubes, especially when you work from the bottom up. To brighten weathered aluminum, Blazin’ Industrial Cleaner is the stronger option. Test either product in a small area before treating the full length.
Yes, Slimy Grimy helps clean oxidation residue, dirt, and surface buildup from boat hulls, siding, and other exterior surfaces. Apply it, allow several minutes of dwell time, then scrub and rinse thoroughly. Light oxidation residue often comes away during this first cleaning, which usually leaves a noticeably cleaner surface behind.
Heavy oxidation on aluminum responds best to Blazin’ Industrial Cleaner, the stronger product in the line. Heavily oxidized gelcoat may still need polishing after cleaning to restore its shine. A coat of wax afterward helps protect the finish going forward.
Slimy Grimy makes a good pre-wax boat cleaner for surface soils, stains, and light residue. Apply it, let it dwell for several minutes, then scrub and rinse thoroughly. Starting with a clean surface means your wax goes onto the finish itself, rather than onto a stubborn layer of grime underneath.
Let the surface dry completely before polishing or waxing, since wax won’t bond well to a damp or residue-covered surface. Check seams and corners for leftover product before you begin. A thorough final rinse makes the waxing step go more smoothly.
Slimy Grimy works well as a dock cleaner for pilings, decking, and other larger dock surfaces. Mix the Granular formula with water and apply it with a pump sprayer, always working from the bottom up. Let it dwell for several minutes, then scrub the surface and rinse it thoroughly afterward.
It helps lift dirt, grime, algae, mildew, and marine growth residue from many dock surfaces. Slimy Grimy is phosphate-free, so it won’t harm fish or flora when used as directed. Work in sections and rinse each area before moving to the next.
As a general rule, allow several minutes of dwell time so that Slimy Grimy can work into the stain before you scrub. Heavier or older staining can benefit from a longer dwell time. Keep an eye on the surface in hot sun or wind, where moisture tends to evaporate quickly.
The one hard rule is not to let the product dry on the surface. Rinse it off before that happens, or mist the area with water to keep it wet. Working in smaller sections makes it much easier to manage dwell time.
Dinghies and tenders clean up well with Slimy Grimy as an inflatable cleaner. Apply it, let it dwell for a few minutes, then gently scrub the surface with a soft brush. Rinse thoroughly with clean water so no product is left sitting on the tubes, the seams, or the floor.
Abrasive pads can damage inflatable material, so leave those in the locker. Dirt, grime, algae stains and mildew stains lift from many inflatable surfaces with gentle scrubbing alone. Test a small area first, since coatings differ between inflatable brands and models.

Slimy Grimy works well as a tile and grout stain remover. Apply it to the stained area and then let it dwell for a few minutes. Scrub the grout lines with a stiff brush, then rinse thoroughly to lift away dirt, grime, and mineral stains from the ceramic tile underneath.
Shower walls, floors, and backsplashes all clean up well with this routine. Older grout stains may need a second application or a longer dwell time to come clean. Wipe the tile dry afterward to keep water spots from forming on the surface.
Slimy Grimy helps clean stains and surface buildup from damp basement and block walls too. Spray it on, let it dwell for several minutes, then scrub the area with a stiff brush and rinse it thoroughly. Spraying it directly on block walls also helps cut musty odors in damp basements.
Open windows or run a fan while you work to help the walls dry afterward. Stubborn stains may need a second application to come fully clean. Cleaning won’t fix the moisture source, so address leaks or drainage to keep stains from returning.
Yes, Slimy Grimy is an effective rust stain remover on exterior surfaces including siding, cement, stucco, and brick. Apply it directly to the stain and let it dwell. Then scrub and rinse thoroughly. For large areas, a pump sprayer and the Granular formula cover a lot of ground very quickly.
Rust streaks from sprinklers, fixtures, and metal hardware are among the most common targets. For rust on smaller fixtures, tools, or fabric, a Slimy Grimy Soak works best. Heavier stains on stucco and cement may take a second pass afterward.
A Slimy Grimy Soak is best for rust removal on smaller items and fixtures around the home. Common examples include sinks, toilets, tubs, dishwashers, washing machines, garden and work tools, and rusted nuts and bolts. Mix Slimy Grimy with water, let the item soak for a while, then rinse thoroughly.
A soak also dissolves orange oxide stains on white towels and clothing. It cleans bleeding rust stains on cars, trucks, and farm equipment too. Dry tools and hardware well after rinsing to slow new rust from forming on them later.
Slimy Grimy can help remove tarnish from both brass and copper. Apply it with a soft cloth and work it gently into the tarnished area. Heavier tarnish may need a second application, so be patient and let the product do the work for you rather than scrubbing too hard yourself.
Rinse the piece thoroughly and dry it right away to prevent water spots from forming. Test in an inconspicuous area first, especially on lacquered or antique pieces. This works well on boat hardware, fixtures, and decorative items around the home.
Formulated without the harsh acids found in many other hull cleaners, Slimy Grimy will never cause any acid burns. It can be used without heavy-duty protective gear, which makes cleaning day much simpler. You can skip the heavy rubber gloves and face shields that most acid-based hull cleaners typically require.
Eye and skin protection is still recommended any time you’re working with a cleaning product. Basic gloves and safety glasses are a sensible choice. Rinse any product off your skin with water, and keep it out of reach of children and pets.
Yes. Slimy Grimy contains no phosphates, so it won’t harm fish or flora when it is used as directed. That makes it a practical choice for boat owners who clean at the dock, at the boat ramp, or anywhere that runoff may eventually reach the water during a cleaning day.
Follow the label directions for mixing and application to keep runoff to a minimum. Rinse thoroughly and avoid pouring concentrated product directly into waterways or storm drains. Using only what the job needs is good practice with any cleaning product.
Blazin Industrial Cleaner is easy to use; especially with our innovative 360° Any Position Spray Bottle.
Directions for Use: Slimy Grimy Blazin’ Industrial Cleaner can be diluted with 1 part water for a safer, easier handling solution that still removes the majority of dirt and stains. Etching possible. Always test a hidden area before proceeding to clean an entire project. Spray surface to be cleaned, then rinse or pressure wash off. Repeat if necessary.
Bug Splatter Batter is a fast-acting bug stain remover for windshields, cars, trucks, and motorcycles. It works in about one minute and usually clears stains with a single application. First formulated in the 1990s, it has become a go-to for busy drivers who log many long highway miles every year.
It’s also widely used on RVs and campers after road trips, and on airplane wings, propellers, and windshields. Around the home, it cleans spider droppings from awnings, porches, and boat or carports. Used as directed, it will not harm any finish.
Yes. Beyond cars, Bug Splatter Batter is commonly used on airplanes to remove bug stains from wings, propellers, and windshields. It also works well on RVs, motor homes, campers, boats, and tractor-trailers. Any vehicle that collects bug splatter on the road or on the water is a good candidate.
Spider droppings on awnings, porches, and car or boat ports clean up well too. Those spots are often hard to scrub by hand, so a fast-acting spray saves real effort. Follow the same one-minute directions on every surface you treat.
Apply Bug Splatter Batter to a cool surface, never a hot vehicle, and always work in the shade. Spray a small area at a time on a wet surface and let it stand no longer than one minute. Keeping the work area small helps you stay within that one-minute window.
Before the surface dries, wash with your favorite car detergent and a soft-bristled brush or sponge. Rinse thoroughly with water when you finish each section, then move on. Used as directed, Bug Splatter Batter will not harm any vehicle finish.
If Bug Splatter Batter is left on too long and a haze appears, any car glaze will remove it. A haze usually means the product sat past the one-minute mark or dried on a warm surface. Glaze clears it away easily with a little light hand or machine polishing afterward.
To prevent it next time, work on a cool surface in the shade and treat small areas. Keep the surface wet and wash it off before the one-minute mark. Following those steps keeps the finish clear and free of streaks.
Greasy Grime is an all-purpose degreaser and stain remover for boats, RVs, ATVs, mowers, lawn equipment, car engines, tires, and wheels. It also handles coolers, ice chests, beach rafts and boards, pool and patio furniture, rubber mats and concrete. One bottle covers outdoor and indoor cleaning jobs around the property.
Inside the house, it helps clean fireplace soot from brick or stone and pet stains on carpet and floors. It also freshens litter pans and garbage cans. Test in an inconspicuous area first, then spray, work it in, and rinse.
Yes. Greasy Grime cleans kitchen and bathroom countertops, fixtures, sinks, tubs, toilets, and shower doors. It also works on dishwashers, stoves, range hoods, refrigerators, ovens, and outdoor grills. Spray it directly onto any greasy or stained areas, work it in with a cloth or brush, and then rinse it clean.
Around the rest of the house, it tackles baseboards, no-wax and tile floors, walls, stainless steel, and vinyl. Plastic blinds, ceiling fans, and window screens clean up well too. Test first on any surface you haven’t cleaned with it before.
Greasy Grime helps clean carpet stains, including red wine, pet stains, and everyday dirt in busy high-traffic areas. Spray it directly onto the stain and work it in by blotting with a clean cloth. Blotting rather than rubbing keeps the stain from spreading out further across the surrounding carpet fibers.
Rinse or blot the area with clean water afterward, then let the carpet dry completely. Greasy Grime also cleans stains on sports equipment, uniforms, and tennis shoes. Test in an inconspicuous area first, since carpet fibers and dyes vary widely.
Greasy Grime works well as a laundry pre-treatment for grease, ink, makeup, lipstick, and baby food or formula stains. Apply it directly to the stain and work it into the fabric. Give it a few minutes to work, then wash the garment as usual with your own regular laundry detergent.
It also cleans food and formula stains from high chairs and baby trays. Test in an inconspicuous area first, especially on colored or delicate fabrics. Treat stains as soon as you can, since fresh stains lift more easily than set ones.
Spray Greasy Grime directly onto the stain, then rub, brush, or work it into the surface. Rinse thoroughly with clean water or wipe the area clean. The 32 oz. spray suits most household jobs, while the gallon jug with remote sprayer easily covers larger items like boats, RVs, and equipment.
Test in an inconspicuous area first, especially on painted, colored, or delicate surfaces. Heavier grease may need a second application or a little more working in before it lifts. Rinse fully so no residue is left behind on the surface.

I LEFT THE BOAT in the water for a week of scalloping & Fishing and got the nice stain line on the boat. My neighbor had some Slimy Grimy in a spray bottle & sprayed it on the line along with a rust stain from the dive ladder screws and it was amazing how Slimy Grimy cleaned the boat.
I recently discovered Slimy Grimy for getting rid of rust in tanks. It works great and won’t hurt the paint.
