CS-530 (Patent Pending) is Easy to Use

CS-530 can be used in washing machines, but it is best utilized when sails are allowed to soak in a trough or tub. Just follow three easy steps:

  1. Dissolve CS-530 in water. Use just enough solution to cover the sails. (CS-530 works in cold water, but the warmer the water, the faster it works.)
  2. Allow to soak. The longer sails are allowed to soak, the less CS-530 is needed.
  3. Rinse with clean water.
