One of the easiest ways to damage your tent is by not drying it as quickly as possible after it gets wet. Storing a wet tent for as little as 24 hours in warm weather is likely to start the process of mildew formation. Mildew can permanently damage the waterproof coatings by causing them to separate from the fabric, but mild to severe staining is more common. Mildew stains are permanent. They cannot be removed without potential harm to the fabric coatings and are not covered by warranty. Even when your tent appears to be dry after use, it is always best to assure it is completely dry before storing. Hang it outside or pile it loosely in your house for a few days, turning it inside and out to assure it has dried everywhere. Never machine dry your tent as the heat can melt the fabric.
