Mildewed Rain Fly

If a rain fly has a few areas of mildew will it still work to repel rain, or do I need to get a new fly?

Question:

If a rain fly has a few areas of mildew will it still work to repel rain, or do I need to get a new fly? Is there anywhere to purchase just the rain fly, or do I have to go all in and get a new tent?

Answer:

Yes, a mildewed tent should still repel water—the smell is just gonna gag you when you’re hunkered down for hours in a storm. Here’s how to deal with those mildew patches:

1. Grab a bottle of McNett Mirazyme.
Mix about a half-ounce into a gallon of water and use a nylon-bristled vegetable brush to scrub the gross spots. (If mildew plagues your whole tent, dissolve a full ounce of Mirazyme into a bathtub and scrub down the whole thing.

2. Set the tent up outside in the shade to let it dry.

3. Now mix 1 cup concentrated lemon juice (the type that comes in those little plastic lemons), 1 cup of table salt, and a gallon of hot water. Use a sponge to bathe the whole tent. Then let it dry thoroughly before packing.

This treatment should resolve the stink issue, but it won’t remove any mildew stains…you’ll just have to live with those. But let them be a reminder! Mildew can be easily prevented: Just make sure it’s thoroughly, completely, 100% dry before storing.

    My tent has a strange, chemical-like odor. To my knowledge, it wasn’t put away wet, and, the smell certainly doesn’t gag me. I haven’t found any mildew on it. Should I be concerned?
