Learned the hard way to buy non marking sneakers for walking on the deck! What is the best overall boat wash you've found and the best cleaner for those tough stains (black marks, grease, tar etc.).
Castrol super clean. Purple bottle. Wal-mart 1 gallon for 12.00. Use 2 cups to every gallon for general cleaning. Half and half for stuborn stains. And full strength for those impossible stains. Also if you have a white boat mix in 3 cups of bleach to the first recipe to get everything white. I use a 3 gallon garden sprayer that I fill and pump up works great. Also make sure you use a soft brush nylon with the bristles softened that way you don't scratch the gel coat. Wax four time a year.
