FAQ:

Q: How is slimy grimy used to clean boats?

A: 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.

Q: How can I get algae stains off my boat?

A: Mix with water in a 1, 2 or 3 gallon sprayer and always work from the bottom and spray upwards. Brown algae stains on boat bottoms magically disappear while spraying. In some cases there is little or no scrubbing. Boat bottoms become showroom clean. Don’t work too hard. Spray away orange oxide stains on exterior surfaces.

Q: Can you use slimy grimy to get rid of rust?

A: Mix with water in a 1, 2 or 3 gallon” “sprayer and always work from the bottom and spray upwards” I recently discovered Slimy Grimy for getting rid of rust in tanks. It works great and won’t hurt the paint.
