I left an old bottle of baitmate in my gheenoe and it got stepped on last time we used it duck hunting. Now I have this chartruese slime on the bottom of the boat. I know I am not only one this has happened too.Hosed as much out as i could. How do you get this stuff off of a smooth surface?

If it sat too long it may be a permanent mark unless you try wet sanding.  What type of surface is it that the stain is on?

Greased Lighting Orange Blast is a super strength auto/degreaser found at Wal/Mart in the automotive dept.

It can be used on any surface and will remove almost any substance known to man

Spray it on let it soak wash it off, for extra stubborn substances you may need to brush it or use a scotch brite pad.

Degreaser makes sense, dont know why i hadnt thought of that....Not a stain, just a slime and smell at back of boat.
