Cleaning interior and exterior fiberglass

[The NY Dad]

I know there are probably tons of threads on cleaning but I just don't have time to search and dig through them to find out what I want to know. I have heard of people using Sno-Bowl and other acidic cleaners on the hull. Will it damage vinyl graphics? Also what about using it on the deck and interior fiberglass, I don't want to damage the upholstery or carpet. If I remove all the upholstery and carpets is it safe to use inside the boat. Thanks

Use the least aggressive product first. Try spray nine then move up if the need arises.

I use a Magic Eraser sponge, works great on scuffs and dock mars.
Not on scum line on hull, though. You need muriatic acid for that, but don't use if bottom is painted. Also Oxcalic acid works well and not as strong.

I use the Attwood Hull cleaner from Walmart on scum lines on the hull and Starbrite Non-Skid cleaner in the cockpit and up on the bow. I use Spray-9 and Simple Green elsewhere. Just watch as some of the cleaners will strip polish/wax so you will need to reapply to seal the gelcoat. For a big hull cleaning I would also look at Colenites fiberglass cleaner.

Slimey Grimey on the scum line. Not acid and works equally as well. Spray it and walk away, come back in 15 minutes and it's gone...

before we start throwing out the names of different cleaners i think the first question we need to ask is what specifically are you trying to clean?.....different cleaners work better on various things.......

+1 on Starbrite Non-Skid Cleaner. I buy it by the gallon.....I've turned on fellow boaters to this stuff for their interiors. If I get any scuff marks that don't come out on the interior, then I get a buff pad and some cleaner wax & buff it out. I've never needed more than those two products for the interior fiberglass except maybe some wax after its cleaned.

Exterior, I'm different because I trailer and only rent slips when on vacation. So Boat soap & wax..
