How to Wash Your Waterproof Jacket
Washing your waterproof jacket and machine-drying it are essential steps to reactivate water repellency and add years to your gear.
Why Is It Important to Wash Your Waterproof Jacket?
Dirt, body oil, sunscreen, smoke and peanut butter smears can all degrade durable water repellent (DWR) performance. Thankfully, rain jacket waterproofing is nothing a little care can’t fix.
Washing your waterproof clothing with a mild detergent made for technical gear (often called “waterproof wash” or “waterproof washing detergent”) and drying it on low heat removes oils and other contaminants that affect performance and prevent the materials from breaking down prematurely. It also helps prolong the life of your gear so you can keep using it for years of soggy, sweaty conditions to come. Please avoid using softeners, as they could compromise the waterproof features of the jacket.
Do Different Shells Require Different Care?
All waterproof, breathable shell jackets—regardless of construction (2L, 2.5L, 3L), membrane type (monolithic, microporous, hydrophilic, hydrophobic), material provider (GORE-TEX), or chemistry (fluorinated, non-fluorinated)—requires the same simple wash and care. It’s true of your Torrentshell from 15 years ago as much as your new Triolet Jacket.
One exception is naturally water-repellent gear, like our Waxed Cotton Jacket. To preserve its function and longevity, spot-clean only as needed. Never put waxed cotton in the wash or dryer, and never iron or steam it. In short; wax, don’t wash.
How to Clean a Waterproof Jacket: A Step-by-Step Guide
Step #1: Wipe Away Dirt & Debris
Look over your rain jacket and wipe away as much dirt and debris as possible. A soft bristle brush will help.
Step #2: Prepare Your Waterproof Jacket
Fasten the main zip and empty pockets of any rubbish, wrappers, treasures or leftover tissues. We recommend keeping smaller inner and outer pockets unzipped because the insides can get grimy.
Step #3: Put Your Rain Jacket in the Washing Machine
Place your waterproof jacket in the machine, preferably a front-loading washer instead of a top-loading machine. If you don’t have a washing machine, hand washing is a great alternative. Fill a bowl with cold or lukewarm water and use a mild, hypoallergenic liquid waterproof laundry detergent. Dip your jacket in the water, stir gently by hand and leave to soak for about 10-15 minutes.
Step #4: Add Waterproof Laundry Detergent
Use a mild detergent, preferably one designed for waterproof clothing. These detergents for waterproof clothing help maintain the function and durability of technical outerwear. We recommend pH-neutral Storm Clothing Wash, which provides waterproofing for coats and helps improve water repellency and restore breathability.
Step #5: Adjust Washing Machine Settings
Set your machine to a regular cycle at 30 degrees Celsius. Once washed, run an extra spin cycle to remove excess water and ensure that there’s no detergent left over. If in doubt, always follow the wash care instructions on the label of your waterproof jacket.
Step #6: Tumble Dry on Low Heat
Heat is critical to reactivating your waterproof clothing’s water-repellent properties. When you need to re-waterproof a coat, putting it in the dryer is the best way to do that. Dry on low heat for at least half an hour or until it’s fully dry and warm. (Steaming can break down DWR, so embrace some wrinkles.)
If you don’t have access to a dryer, an iron is one of the best alternatives to drying your waterproof rain coat. Let your jacket fully air-dry and set your iron to low (either the 1 or 2 setting should be low enough) without steam. Place a thin, dry cloth or towel between the garment and iron and iron away.
Step #7: Get Back Outside
Remember: dirt is credibility, but clean is performance.
The Best Detergents for Washing a Waterproof Jacket
Standard detergents that aren’t designed for waterproofing clothes can impact the durable water repellent (DWR) finish and lead to premature wetting out. After testing a dozen waterproof jacket cleaner options, we recommend Storm products, a pH-neutral detergent made for technical outerwear and equipment. You can also look for mild detergent options at your local supermarket. Choose a water-based—not oil-based—biodegradable liquid detergent free of dyes, whiteners, brighteners or fragrances. Look for detergents for sensitive skin. If it’s safe for sensitive skin, it’s safe for your gear.
How Does Waterproof Clothing Work?
DWR is a coating added to waterproof clothing to help moisture bead up and roll off the outer surface. It prevents the fabric from becoming soaked from the outside and prevents you from getting cold, clammy or wet, which could be life-threatening in extreme conditions. The membrane is the actual “engine” of your waterproof gear. It’s the physical material barrier inside a laminated fabric that keeps water from getting in and allows water vapour, sweat and heat to escape. DWR is an extra protective coating; the membrane is the workhorse.
For decades now, DWR coatings have relied on per- or polyfluorinated chemicals (most often referred to by their acronyms: PFCs, PFAS, PFOAs or PFOS). They’re strong, heat-stable, and water- and oil-repellent chemicals, and on waterproof gear, they’re typically applied to the exterior of the fabric and the membrane. They are extremely effective at repelling water, but these non-biodegradable chemicals come with an environmental cost, particularly during the manufacturing phase and after the gear has lived its useful life because these garments are more challenging to reuse and reprocess.
That’s why we are making all of our membranes and water-repellent finishes without PFAS by 2025. (PFAS, which stands for per- and polyfluoroalkyl substances, is the latest terminology to encompass this class of perfluorinated chemicals. We use PFAS as an umbrella term, but at Patagonia, if your water-repellent finishes and membranes are made without PFAS, they’re also made without PFCs, PFOS and PFOAs).

How Do I Know When to Wash a Waterproof Jacket?
If you’re wondering about the best time to re-waterproof a coat, it depends. If it looks dirty; wash and dry it. If you see “wet out”—when the exterior of the fabric looks wet because the DWR coating has worn off, but the inside (and you) aren’t wet—that’s another sign to wash your waterproof jacket. Wet out is a normal process. You’ll usually first spot it in areas that get the most friction, like your cuffs or your shoulders where your backpack straps sits.
As a rule of thumb, we recommend washing your waterproof jacket made without PFAS after wearing it 7-10 times or after a long trip. Those with PFAS can typically be washed after 30 times of use.
If water still doesn’t bead up on your shell after a wash and dry, then it's time to reproof it. Choose a fabric waterproofing solution that doesn’t use PFAS, available online and at most outdoor gear stores. We recommend Storm Clothing Wash. Wash-in reproofer treatments can be easier to use because they coat the entire item in the wash, but spray-on options are as effective so long as you're vigilant about covering all areas.

Does Gear Made Without PFAS Perform Differently?
Every Patagonia waterproof product—made with or without PFAS—has gone through an extensive, years-long testing process in our lab and in the field to ensure that even in the wettest weather, our waterproof rain jackets and trousers trousers will keep you protected.
If you still have gear made with PFAS, we recommend you keep it to respect the resources that went into making it. Gear made with PFAS performs well and because the chemistries are inert (chemically inactive), skin exposure isn’t a concern.
Beyond our commitment to complying with regulations, our broader goal is to create change. Going forward, buying gear made without PFAS helps send a message to stop the industrial manufacturing of these harmful chemicals. By washing your waterproof rain jacket and trousers, you're also doing your part of keep gear in play so it stays out of the landfill longer.
