Hull cleaner
 

On and Off hull cleaner is the real deal! The brown stain around the waterline that have driven me crazy were gone with just a few wipes of On and Off on a clean tee shirt! Justbe sure to wear heavy rubber gloves and avoid inhaling the fumes. Best product I have used to get rid of stains.....

Compounding didn't take it out?

Also very good is FSR a little pricy but easy to use,and a cheap fix is Bar Keepers Friend,good for stainless steel, chrome, fiberglass,brass.

They really take the stain out fast.

My brown stain wiped off with my finger but then again I have a Ropolene (plastic) hull!:) Power washer is all that is needed to get out any stain.

you guys are wasting your money. lysol toilet bowl cleaner wipe it on with a damp sponge hose it off $2.50 a bottle. The best cleaner i have ever used on my boats.

That is disgusting. I hope you washed your hands:biglaugh:


On off is serious...esp if you have heavy marine growth/barnacle attachments in difficult places (like inside the seawater intake cavity in an outboard or outdrive. etc. it is battery acid I think, it just eats at it. Make use you wash it off well afterwards and don't get it on a galvanized trailer...it will turn very black and be like that forever.

FSR works on rust stains in your fiberglass that power-washing does not change.

Bleach works on most normal stains and is really cheap. Don't wear your Sunday best when you use this.

Bar Keepers friend for the stain along water line,also works well for rust stains. $2 for a can. Rinse off good right away and keep away from galvanized also.

Pool shock, is twice the strength of normal bleach, i bleach the boat after all trips! no wax for me lol

On and off is great stuff, it also cleans non-skid very well. Just don't breathe the fumes.

I agree, Mary Kate On-Off is awesome stuff. Takes my brown waterline stains right out and a little goes a long way.

That On-Off is great fro that scumline stuff on the hull- I've had very good luck with it.

+1 On the Lysol Toilet bowl cleaner. Incredable!!
