I must be running a little rich - have exhaust soot on and under the swim platform that will not come off with simple green and a light scrub brush. Does anyone have a good solution?

Go to Home Depot and buy a spray bottle of Zep 505. I just did my whole transom with paper towels while it was on the trailer. I was impressed! It cleans the soot instantly and it wipes off to to nice shine. No streaks. Works good on the drive, too.

Flitz works well too.

I always say to spray on "Fantastik" and leave it on for 3-5 minutes and then soap and water and a sponge. It's the easiest way everyone tells me!

I use mean green , my wife picks it up at the dollar store, we use it on every thing. NOT SIMPLE GREEN, MEAN GREEN.

Maybe if you guys would wash and wax your boat more than once a year it would come off with the whipe of a finger like mine, i dont know maybe baja has good gel coat but all i do is take a damp towl and whipe it right off.

Purple power from Wal-mart works great. And its only $3.84 a gallon! Its in the automotive department.

Yep....lack of wax causes that. Use a good cleaner wax to get it all off. Then just keep it waxed. Mine comes right off with a light solution of boat soap and a sponge.
