it was time to clean the boat. black midew in the calking, black spots on the gel coat, stains from leaves, the the cushions looked grey, the nonskid was stained....there are all kinds of acids and elbow grease solutions to this but i stumbled on an unbelievable product: EASY ERASE PADS BY MISTER CLEAN!!!!!!!!!
A light swipe takes care of most of the ills. The nonskid chews them up, but really good stuff! The boat looks so happy now!
