What's everyone using? I've always used Power one. What's the latest and greatest?

the works tub and shower cleaner. cheap and you can get it at the grocery store.

Then buff and wax the bottom to seal the pores of the gel

Biokleen’s fiberglass and rv cleaner. I use it on a boat that is kept in a seasonal slip, that has no bottom paint. 1-2 applications and its done, looks like new

PowerOne is still the best bang for the buck . . . .been using this stuff for years works best on a dry surface. i would use boat for the weekend and shoot it on monday with a spray bottle then hose it off with some soapy water after it does its thing. Watch it on aluminum trailers though its acidic for those not familiar with it

FOY - Power One #1

Muratic Acid in pump garden sprayer. Spray on and then hose off after 30 seconds.
It does not play well aluminum either and the fumes suck.

Ringo gel is great as well.. but as stated above any of them leave the gel porous and the stains will come back faster.

i think the works uses phosphoric acid which is a little easier on aluminum. doesnt seem to bother my manning aluminum trailer, but a good whiff will still burn your lungs.

i ceramic coated one side of my boat last year (three coats). seemed to help allot vs the uncoated side.

I'm thinking about having the bottom painted black then I don't have to worry about it. Lol
