Hi,
I've seen the following problem on both clean boats and dirty boats (and my boat which I try to keep in the clean category!). In between the raised "teeth" (diamonds) of the non-skid, there are black specs. No matter what cleaning product of tried and no matter how hard I brush, they won't come off. If I give a quick rub with a finger nail between the diamonds, the black specs come off. I assume this is residue left behind by water from cleaning that evaporates and then the sun bakes it onto the surface. It is not mold or mildew. I've tried various cleaners and have been on the look out for the perfect brush to try (stiffer, shorter bristles but not too aggressive). I've thought about trying my low-powered pressure washer with a 15 or 25 degree nozzle, but don't think it will really work and am worried about using it on the decks. Since it seems to be a common problem from inspecting other boats at the marina, I thought I see if anyone has the magic bullet for this cleaning task before I turn it into a big science experiment. I'd love to have the spaces between the diamonds clean.
Thanks for any tips.
