Good Day to Everyone: The marina where my slip is located is very close to two steel mills. As you can imagine the white decks of my 1985 Mac 25 get pretty grimy. At the present time, at least twice a week, I use Starbrite Non-skid deck cleaner, (that may not be the exact product name), and although it gets the deck pretty clean it does require some serious scrubbing. Does anyone have any other suggestions/products/homemade concoctions on how to keep my decks clean? Also along with a thorough scrubbing after each sail I hose her down before I leave. Thank you for any ideas that you might have. Wayne.
