Did awesome job cleaning a boat interior after sitting under a canopy all winter....
A fellow boat owner recommended these to clean a fiberglass boat interior.  Used these on the interior fiberglass as well as the cushions.  After using detergent and a nylon bristle brush w/ handle before these, I was truly amazed at how these just seemed to lift away the dirt and dark stains that seem to magically appear through the course of the off season.  The only negative, forgive me for nit-picking, but I just wish they would hold up better on the boat deck.  Since it is is somewhat rough textured these seem to disintegrate rather quickly.  This is probably just a case of wishful thinking on my part that there would be a product that cleans like these but is tough like those green scratch pads.  I will definitely use these in the future as they work much better than the pink detergent I purchased at the local marine products store.
