CS-530 (Patent Pending) was developed specifically to remove mildew and algae stains, and to clean and brighten sails, dodgers, and similar marine materials. It is safe and effective for all colors and all sail cloth, including Dacron, Nylon, Kevlar, and Laminates. Avoid using on leather trim sometimes found on dodgers and sails.


  1. Fully dissolve CS-530 (Patent Pending) in water. This may take a few minutes, depending on the temperature of the water. Stirring will hasten the process. Use just enough water to cover the sails.
  2. Place sail(s) in water and allow to soak. Clean many sails together or one after the other. Solution can be re-used for approximately 6-12 hours before losing maximum effectiveness, but will continue to work after that.
  3. Rinse with clean water. If material is not rinsed, a white residue will be left behind. The residue is not harmful but diminishes the look of the material, especially on colors.

For Machine Washing. We recommend using 8 ounces (in volume) of CS-530 per load.

Other. Keep container closed to avoid absorption of moisture.

Note: Before using, we recommend always testing a small area of material.
