To clean a tent: never machine-wash it. Hand-clean with lukewarm water and a tent-safe wash (no detergent or bleach), spot-treat mold with an enzyme mildew cleaner, rinse the zippers, and — above all — dry it completely before storing. Most “ruined” tents were just packed away damp.
Why machine-washing ruins tents
The spin cycle and harsh detergents strip the DWR and the urethane coating and stress the seams — the exact things that keep you dry. After cleaning, it's worth checking whether the tent needs re-waterproofing.
How to clean a tent, step by step
Never machine-wash it
A washing machine's agitation tears seams and strips the waterproof coating. Tents are always cleaned by hand. This is the one rule that matters most.
Shake out and spot-clean
Pitch or hang the tent, shake out the grit, and sponge dirty patches with lukewarm water and a tech-fabric wash — never detergent or dish soap, which strip the DWR.
Soak only if it really needs it
For a grimy or smelly tent, soak it in a tub of cool water with a tent-specific cleaner, swish gently, then rinse until the water runs clear.
Treat mold and mildew
For black spots and that musty smell, use an enzyme-based mildew cleaner made for tents, work it in, and let it sit per the label. Bleach kills the smell but also the coating — avoid it.
Care for zippers and poles
Rinse grit out of the zippers (it's the usual cause of snags) and wipe the poles. A little zipper lubricant keeps them gliding.
Dry it completely before storing
Hang it fully open until bone dry — packing a damp tent is exactly how mildew starts. Store loosely in a breathable bag, not crammed in its stuff sack long-term.
FAQ
Can I put a tent in the washing machine?
No. The agitation and spin damage seams, mesh, and the waterproof coating. Always hand-clean a tent with cool water and a tent-safe wash.
How do I get the mildew smell out of a tent?
Clean it with an enzyme-based mildew remover made for tents, let it dwell per the label, rinse, and — most importantly — dry it fully. Mildew smell almost always comes from storing the tent damp.
What's the best tent cleaner?
A dedicated technical-fabric wash or tent cleaner. Avoid household detergent, dish soap, and bleach — they strip the DWR and shorten the tent's life.
How do I store a tent so it stays fresh?
Bone-dry, loosely packed, in a cool, dry place — a breathable bag or pillowcase beats a tight stuff sack for long-term storage. Never store it even slightly damp.
