We recommend using a non-abrasive sponge, cold water, and a non-detergent soap. Gently scrub soiled areas by hand, being extra gentle on coated areas of the floor and fly. Avoid household cleaners such as harsh dish soaps, bleach, spot removers, or laundry pre-soaking products. Be sure to thoroughly air dry your tent to prevent mold from forming.
