Slimy Grimy works better than anything else I have tried; also non toxic, no acids, works for many other things. It’s a little pricy for a spray bottle but I was able to do my 23′ cuddy and still had some left over.
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.
