SeaDek nonskid deck material has become a popular upgrade on many saltwater fishing boats today. It's soft on your feet and enhances the appearance of boat interiors. But cleaning it after a day of fishing can be tough, especially when there's blood, as well as tracked-in dirt and grime, on the deck. Using the low setting on a power washer helps immensely. In addition, SeaDek now offers Dek Magic (about $25 for a 32-ounce spray bottle), designed specifically for cleaning the closed-foam EVA material. It works particularly well to eliminate dried fish-blood stains, I have found.
