A few days ago I gave my B28's fiberglass decks a good cleaning with Soft Scrub w/ bleach. I brushed it in thoroughly and let it soak a few minutes before rinsing.<br /><br />Returning to the boat today the difference was noticable! I'm thinking a few more cleanings will clean and brighten the decks considerably. But I'm wondering if I need to worry about the "soft" scrub's abrasiveness, I'm also curious how the 3M non-skid deck cleaner's performance would compare.
