How to Clean a Rain Jacket | Keep the Water Beading

For the full breakdown, see our best Equestrian Rain Jacket guide.

Regular washing keeps your rain jacket performing and extends its life, but the wrong detergent or dryer setting can ruin the waterproof membrane. The golden rule that overrides everything is your jacket’s care label — check it before any cleaning. For most waterproof shells, the process is straightforward: a gentle machine wash with liquid detergent, a thorough rinse, and low-heat drying to reactivate the water-repellent finish.

Washing Your Rain Jacket: Step by Step

Pre-treating and prepping the jacket properly makes the wash cycle far more effective. If you’re wondering how to clean a rain jacket without damaging it, start here.

• Pre-clean: Wipe loose dirt and mud off the exterior with a damp cloth, then treat any stains with a fabric cleaner before washing.
• Close everything: Zip the front, both pockets, and pit zips completely, then fasten any loose flaps, Velcro, and straps so nothing snags in the machine.
• Wash alone or with light items: Never wash your rain jacket with heavily soiled clothing — dirt can grind into the membrane and clog the fabric.
• Use the right detergent: A small amount of liquid, free-rinsing soap is all you need. Avoid powder detergents, fabric softeners, bleach, stain removers, and conditioners, which leave residues that block water from beading.
• Choose the cycle: GORE-TEX recommends a machine wash at 105°F/40°C, but many brands specify a synthetic cycle at 86°F/30°C with a low 600-rpm spin. Pick the colder option if your care label doesn’t specify.
• Rinse twice: Run an extra rinse cycle to flush every trace of soap from the fabric. Detergent residue is one of the most common reasons water stops beading.

Hand washing works well too, especially if you’re off-grid. Use cool water and a gentle detergent, rinse thoroughly, and dry the jacket out of direct sunlight. GORE-TEX says to minimize spinning in the machine, so a gentle cycle paired with a low spin protects the membrane fibers.

Drying and Restoring the Water Repellent Finish

Drying correctly is half the battle — it reactivates the durable water repellent (DWR) that makes water bead up and roll off the fabric. Hang the jacket to dry completely, or tumble dry on a warm, gentle cycle. If your dryer has a low setting, use it; high heat can delaminate the waterproof membrane.

GORE-TEX advises tumbling dry for an additional 20 minutes after the jacket is already dry to reactivate the DWR finish. If water stops beading after washing and drying, the DWR has worn off — reapply a dedicated DWR treatment product. Do not apply DWR to GORE-TEX SHAKEDRY™ garments, because they have a permanent beading surface built into the outer fabric. SHAKEDRY items should only be machine washed on a delicate cycle at 105°F/40°C — never dry cleaned, tumbled, ironed, or bleached.

Common Mistakes to Avoid

Most rain jackets get ruined by a handful of well-intentioned errors. Skip these and your jacket will shed water for years:

• Fabric softener or bleach: Both strip the DWR coating and can break down the membrane’s glue bonds.
• Powder detergent: It doesn’t dissolve fully and leaves abrasive residue inside the fabric.
• Forgetting zippers and Velcro: Snagged zippers and torn Velcro are the most frequent damage from machine washing.
• Skipping the extra rinse: Soap left in the fabric absorbs water instead of repelling it.
• High-heat drying: Anything above a warm gentle cycle risks delaminating the jacket’s layers.
• Storing it damp: Always hang dry completely before putting the jacket away, or mold and mildew will set in.

If wrinkles appear after washing, steam them out on low heat or iron with a cotton cloth barrier between the iron and the jacket — never touch the iron directly to the fabric. For PU-coated jackets, turn the jacket inside out before washing to protect the coating from friction against the drum.

FAQs

Can I use regular laundry detergent on my rain jacket?

Plain liquid laundry detergent is acceptable for many waterproof shells, provided it’s free of fabric softeners, bleach, and added perfumes. Some brands recommend non-biological liquid detergent or a specialized technical cleaner as the safest choice for delicate membranes.

Why does water soak into my rain jacket instead of beading up?

That’s a sign your DWR finish has worn off — a normal result of wear and repeated washing. Wash the jacket with a gentle liquid detergent, dry it on a low-heat cycle, and apply a fresh DWR treatment to restore the beading effect.

How often should I wash my rain jacket?

Wash it whenever it looks dirty or stops performing, rather than on a fixed schedule. The more dirt that sits on the fabric, the faster the DWR gets clogged, so cleaning a visibly soiled jacket actually extends its lifespan.
