Washing your rain jacket correctly restores its waterproof finish. Follow these steps to clean, re-waterproof, and extend the life of your shell.
Quick answer
Wash your rain jacket in a front-loading machine with a technical cleaner, then tumble dry low to reactivate the DWR. If water still soaks in, apply a spray-on or wash-in DWR treatment. Avoid fabric softener and bleach.
Why washing matters more than you think
Dirt, oils, and sunscreen clog the fabric's pores and mask the DWR finish, making the jacket feel wet even when it's still waterproof. A proper wash removes residues so water can bead again. Check the care tag first; if it says do not machine wash, hand wash with a technical cleaner and rinse thoroughly.
What you need before you start
Use a technical wash or a mild, fragrance-free detergent. Never use standard laundry detergent, fabric softener, or bleach—they leave behind coatings that attract water. For re-waterproofing, choose a spray-on DWR for targeted coverage or a wash-in DWR for all-over treatment. A front-loading washer is gentler than a top-loader with an agitator.
Step-by-step rain jacket care
- 1. Prep the jacket: Empty all pockets, close zippers and Velcro, and loosen any drawcords. Brush off loose dirt or mud. Checkpoint: If the jacket has a removable hood or liner, detach it before washing.
- 2. Wash with technical cleaner: Use a front-loading washer on a gentle cycle with warm water (check the tag). Add the recommended amount of technical cleaner. If hand washing, soak for 10–15 minutes and rinse until no suds remain. Mistake to avoid: Never use standard detergent or fabric softener—they leave residues that attract water.
- 3. Rinse twice: Run an extra rinse cycle to ensure all soap is removed. Residual detergent can prevent DWR from bonding. Checkpoint: Water should run clear, not slippery.
- 4. Dry to reactivate DWR: Tumble dry on low heat for 20–30 minutes. The heat helps redistribute the existing DWR. If the care tag says no tumble dry, hang dry and skip to step 5. Mistake to avoid: High heat can damage the fabric and seam tape.
- 5. Re-waterproof if needed: After drying, test by sprinkling water on the fabric. If it soaks in instead of beading, apply a spray-on or wash-in DWR treatment according to the product instructions. Checkpoint: For spray-on, focus on high-wear areas like shoulders and cuffs.
- 6. Heat-set the treatment: If the DWR instructions call for it, tumble dry on low for another 10–15 minutes or iron on low with a cloth barrier. This helps the treatment cure. Mistake to avoid: Never iron directly on the fabric or use steam.
- 7. Store properly: Hang the jacket on a wide hanger in a cool, dry place. Avoid stuffing it into a tight pack for long periods. Checkpoint: Proper storage prevents creases and mildew.
