Item Description

Prevents mildew stain growth

Marine 31 Mildew Stain Guard is the solution to a common problem that plagues all boaters - mold and mildew stains on vinyl surfaces. This high-tech vinyl sealant forms a clear coating that protects against UV rays, body oils, salt, and most importantly, stubborn stains caused by mold and mildew. Treated surfaces will retain their flexibility while being well protected against the damaging effects of nature.

If you're a boater, chances are you've dealt with stubborn mildew stains on vinyl cushions. If you're reading this product description, chances are you've been less than satisfied with the performance of other so-called marine mildew protectants. Fortunately for you, we've dealt with every type of stain caused by mold and mildew there is, and developed a product to stop it in its tracks - Marine 31 Mildew Stain Guard.

Marine 31 Mildew Stain Guard is far more than a vinyl protectant. This high-tech vinyl sealant actually forms a clear coating over treated surfaces, creating an impenetrable barrier of protection that prevents stains caused by mold and mildew. In addition to providing durable protection against mold and mildew staining, treated surfaces will be noticeably easier to clean. Regular maintenance can be performed with a dampened microfiber towel. Marine 31 Mildew Stain Guard allows you to spend more time enjoying your boat, and less time performing laborious cleaning tasks. Application is as simple as spraying on and wiping off. It only takes seconds to apply, but the protection provided lasts months! The clear coating resists UV-induced fading and discoloration as well, making it the best marine vinyl protectant the boating world has ever seen!


  1. Ensure surface is clean and out of direct sunlight.
  2. If mildew stains are already present, use Marine 31 Mildew Stain Remover first.
  3. Spray product directly onto microfiber or terrycloth towel.
  4. Gently massage into surface, making circular, overlapping motions.
  5. Wait 2 minutes then lightly buff with a clean, dry microfiber towel.
  6. Apply a second coat 10 minutes later to ensure even coverage.
