Water is essential to sailing, and also to the persistent enemy of clean, bright sails -- mildew. Keeping your sails aired and dry will help prevent the occurrence of mildew and a little sun now and then is also helpful. If mildew does attack, it is important to take care of it as quickly as possible to keep it from spreading and embedding itself in your sails.
1. Place your sail on a clean, smooth surface in an open area with good ventilation.
2. Use the soft-bristled brush and soap and water to give Dacron sails a general cleaning.
3. Scrub mildew from Dacron sails with the soft-bristled brush and a 3 percent solution of bleach and water -- 7 1/2 tablespoons of bleach per gallon of water.
4. Rinse the sails thoroughly with clean, fresh water.
5. Air-dry the sails by hanging them up in a well-ventilated area. When they are completely dry, fold them loosely or roll them up.
