Every stain on this page tells the same story: a boat, RV, truck, or outdoor surface that looked impossible to clean — until it wasn’t. Below are real before-and-after results from Slimy Grimy customers dealing with rust on boat trim and hardware, heavy buildup on swim platforms, bug splatter on trucks, and staining on brick, fencing, and concrete. No pressure-washer marathons, no scrubbing until your arm gives out — just spray, wait, and rinse.

Boat Cleaning Results
Rust and stubborn buildup don’t just stain the hull — they show up on rub rails, swim platforms, and boat hardware too. These results show Slimy Grimy clearing both rust streaking and heavy surface buildup from boat trim without scrubbing.
This boat’s rub rail had collected both rust streaking and dark staining at the base after sitting outdoors. A Slimy Grimy application cleared both the rust and the staining in one pass, bringing the tan-and-burgundy stripe back to its original color.
Rust had bled out from a metal fitting onto this boat’s bench or swim platform, leaving a dark streak next to the mounting hardware. Slimy Grimy dissolved the rust stain directly around the fitting without needing to remove the hardware first.
This close-up shows Slimy Grimy actively breaking down thick surface buildup on a boat’s swim platform or transom edge — the kind of residue that typically requires heavy scrubbing. The spray dissolves the buildup on contact, clearing the surface down to the wood or fiberglass underneath.
Another action shot showing Slimy Grimy working on dark rust and oxidation along a metal rail or trailer edge. The two panels capture the spray mid-application, lifting the discoloration off the metal in real time.
Stain Removal
Rust stains show up anywhere metal hardware sits against a painted or concrete surface — storage bins, driveways, dock posts. These results show rust lifting from both painted plastic/metal and bare concrete without acid-based cleaners.
Rust had dripped down the inside of this white storage bin or cooler, leaving orange streaking across the surface. Slimy Grimy removed the rust discoloration and restored the bin to solid white without scratching the plastic.
A rust stain had soaked into this concrete surface, likely from a metal object left in place too long. Unlike acid-based rust removers that can etch concrete, Slimy Grimy lifted the stain out while leaving the surface texture unaffected.
Bug splatter bakes onto paint fast, especially on front bumpers, grilles, and mirrors after highway driving. The vehicles below were cleaned with Bug Splatter Batter, Slimy Grimy’s dedicated 1-minute bug and grime remover, safe for paint and clear coat.
This side mirror was covered in dried bug splatter after a highway trip. Bug Splatter Batter was sprayed directly on and rinsed off, clearing the residue without any scrubbing or streaking on the mirror housing.
A front grille and hood loaded with dried bug splatter — the kind that usually needs a clay bar or heavy degreaser to fully remove. One application of Bug Splatter Batter cleared it in a single pass, leaving the paint and chrome trim untouched.
Exterior Cleaning
Slimy Grimy isn’t limited to boats — the same formula clears stubborn staining and buildup from brick, wood fencing, and other exterior surfaces around the house.
This brick foundation wall had developed dark staining from ongoing moisture exposure. After a Slimy Grimy application and rinse, the brick returned to its natural red-brown color with the staining fully lifted.
Years of weather exposure had turned this wood privacy fence a dull grey with visible dark staining. Slimy Grimy restored the panel to a warm golden-brown finish without requiring a power wash or wood brightener afterward.
A similar result on a picket-style fence: staining and weathering had dulled the wood grey, and a Slimy Grimy treatment brought back the natural warm wood tone across the full run of pickets.

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.
