How to clean a rainproof jacket
Close zips, wash the jacket by itself with a technical cleaner on a gentle cycle, then tumble dry low to revive water repellency. Reproof only if water no longer beads. Follow the care label.

Clean a rainproof jacket by zipping everything closed, washing it by itself with a technical cleaner (not regular detergent or fabric softener) on a gentle, cool-to-warm cycle, then drying on low heat to revive the water-repellent finish. Reapply a DWR treatment only if it still wets out after a proper wash and dry. Always follow the garment’s care label first Helly Hansen cleaning guide Craghoppers wash & reproof.
When to clean a rainproof jacket
It’s time to wash when you see visible dirt or stains, notice odor, or the face fabric starts absorbing water instead of beading (wetting out). Wetting out also hurts breathability, making the jacket feel clammy Helly Hansen cleaning guide.
Pre-wash checks to protect your jacket
Prepare the jacket
Care label and closures
Check the care label and follow its temperature and drying directions. Before washing, zip up all zippers, close hook-and-loop tabs, and secure cuffs and hood drawcords Helly Hansen cleaning guide. Brush off or wipe away loose dirt first to help the wash work better Craghoppers wash & reproof.

Machine washing: the safe method
Use a technical cleaner and gentle settings
Avoid standard laundry detergent, bleach and fabric softener; these can leave residues that attract water and reduce performance. Use a technical cleaner designed for waterproof-breathable garments and follow the amount on the bottle Helly Hansen cleaning guide Nikwax care advice Craghoppers wash & reproof.
- Wash the jacket by itself (or only with similar shells) to reduce abrasion Helly Hansen cleaning guide.
- Select a gentle or delicate cycle and cool-to-warm water, within the label’s limits Craghoppers wash & reproof.
- Before starting, wipe out the washer’s detergent drawer so old detergent residue doesn’t affect water repellency Nikwax care advice.
Hand washing if needed
If the label discourages machine washing or the jacket is delicate, hand wash in lukewarm water with a technical cleaner, gently agitate, then rinse thoroughly. This approach is supported by aftercare brands and works well for technical shells Nikwax care advice.
Drying and reviving water repellency
Dry according to the care label. Many shells benefit from a low or medium tumble dry to help reactivate the factory-applied DWR on the face fabric Helly Hansen cleaning guide Craghoppers wash & reproof. Avoid high heat that your label does not allow, as it can damage seam tape and trims Helly Hansen cleaning guide.
Reproof only if needed
If the jacket still absorbs water after a proper clean and dry, reapply a DWR treatment. You can use a wash-in proofer in a second cycle or a spray-on proofer applied evenly to the clean, wet jacket. Follow the garment and product instructions; some proofers do not require heat to activate Helly Hansen cleaning guide Nikwax care advice.

Common mistakes and quick fixes
- Do not use regular detergent, bleach or fabric softener on technical shells; they can impair breathability and repellency Helly Hansen cleaning guide Craghoppers wash & reproof.
- Avoid high dryer heat not permitted by the label to protect seam tape and coatings Helly Hansen cleaning guide.
- If wetting out persists: ensure the washer drawer was clean of detergent residue, rewash with a technical cleaner, dry on low heat, then apply a suitable DWR treatment Nikwax care advice.
