How to Kill Mildew on Nylon Fabric

Dry the fabric. Nylon fabric dries easily, so a couple of hours in direct sunlight should do the trick. Mold spores cannot grow on any surface without moisture, so drying your nylon will neutralize the mildew.

Remove the dried spores from your nylon outdoors. Neutralized spores do not equal dead spores, so if you do not remove the spores by hand, they may regenerate. Use a dry cloth, sponge or brush to thoroughly wipe down the entire nylon surface.

Wash your nylon fabric. Unlike some other fabrics, such as cotton, nylon contains no nutrients that mold can devour for growth. As a result, mildew can only grow on nylon if external nutrients exist, namely dirt. By removing dirt from your nylon fabric, you can ensure that mold never grows. You can machine wash nylon fabrics, but use a “Gentle” or “Delicate” setting. Use your preferred laundry detergent, but do not use bleach.

Dry the nylon fabric one more time. Use sunlight for best results. If you choose to machine dry, tumble dry it using a low temperature. Drying your nylon further ensures that mold spores do not have a chance to regenerate.
