I use On/Off every year in the fall for many years on many different boats and have never had a problem. What gives???

Ditto - I use On/Off for coffee stains; I was told it wouldn't damage the gelcoat, just everything else. What gives?

Been using On-Off for years with no problems.

Yep, same here. Pretty much every marina/boat dealership uses it as well.

I watch the guys in the Marina use on/off and a pressure washer year after year and makes them boats look like new after sitting in the river for the season .

I had some maple leafs get under my cover on a cold fall day up here then it rained for a week......I had clearly visible maple leaf stains on the deck.......I was freaking out to say the least.......I used Mequiers 3 step process,(3 seperate bottles) medium oxide cleaner, sealer, then pure boat wax with a rotary buffer......not a trace they were ever there.......I was very impressed!!.....you'll end up doing the whole deck though to make it look even

Amazing, huh? And that stuff is less than $2,- a gallon. Works like a champ and as long as you wash after about 10 minutes it cleanes it to look like new as well as no harm done to paint or gelcoat. Maybe I should rebottle some of it and sell it for $29,- a quart?? Anyone want to buy a bottle of magic for $29,-??? Just PM me, I will send it right over...

The Clorox clean up contains a lot of bleach as well.
