In another post someone mentioned using the Mr. Clean magic eraser on ropelene. I tried it and the results were dramatic. My transom had become awfully stained by our infamous bay scum. I tried everything outside of hull cleaner which is a harsh chemical that will eat up a gel coat. I don't know what it does to ropelene. I had tried everything else..bleach, soap, and power washer but rubbing a Magic Eraser on it immediately a layer of scum and other stuff came loose..looks new now. I think, this white cleaning sponge may be some sort of micro abrasive material. After a rub down on the transom the finish is clean and beading water again like it was waxed.
I will buy me a box of them.
