There is no way to calculate how much cleaner you need for a boat because each boat has different requirements. The variables include what the time of dirt, growth, stains, etc. you are trying to remove, the surface material and the age of the boat and of the dirt, growth etc. that you are trying to remove. One 50 ft boat may require 2 to 3 bottles of Algae Strip, on another 6 to 8 or even more if it is heavily encrusted with barnacles. The same variables apply to all cleaners. To complicate matters even more, some cleaners are concentrated. For example, Boat Clean Plus can be used straight or reduced by 15 or 20 to one with water depending on if you are degreasing a motor or just washing the boat.

It is easier to calculate the requirements of polishes or protectors because we can assume that you have cleaned and prepared the surface so the coverage will be similar. For example the coverage of VS721 is about 400 sq. ft., Sure Step has a coverage of about 200 sq ft.
