Tent Care & Maintenance

How to clean a tent with mold

Mold on a tent fabric is usually a symptom of storing or packing the shelter while it is still damp. Once it appears, the goal is to remove the staining, kill the spores, and dry the tent properly so it does not return.

Step 1 — Dry the tent first

Spread the tent out in open air, away from direct high heat, and let it dry completely before touching it with any cleaning product. Most surface mildew will flake off a dry tent on its own.

Step 2 — Brush off loose spores

Take the tent outside and shake or brush away the dry growth. Do this before any water is introduced, so spores are not spread around the rest of the shelter or onto other gear.

Step 3 — Wash the affected fabric

• Use lukewarm water with a mild detergent or a soap designed for technical outdoor fabrics.
• Work the solution into the stained areas with a soft brush or sponge.
• Rinse thoroughly so no detergent residue is left in the fabric.

Step 4 — Treat and dry again

Hang the tent in a shaded, well-ventilated space and let it dry fully before it is packed away. Packing a tent that is still damp is the most common reason mold comes back.

Dry tent, dry storage. Mold returns quickly wherever a shelter is folded up while damp.

General upkeep habits

• Dry the tent body and fly separately after every trip, in the shade.
• Keep the shelter in a breathable bag or loose cover rather than a sealed plastic sack when stored long term.
• Check the seams, zippers and poles for wear while the fabric is still spread out.
• Store it in a dry, ventilated space away from direct sunlight and heat.
