If rain no longer rolls off the jacket in droplets, it doesn't automatically mean the waterproof membrane is damaged. Often the water-repellent treatment of the face fabric, the so-called DWR, is exhausted or soiled first. With the right sequence the beading effect can often be restored: read the care label, wash gently, use permitted heat, test and only then reproof.
What is the difference between waterproof and water-repellent?
On many rain and hardshell jackets a membrane keeps liquid water out. Over that sits the face fabric with a water-repellent treatment. This makes droplets bead instead of turning the fabric dark and heavy. If the DWR decreases, the membrane can still be intact. The jacket can still feel wet on the outside, heavier and uncomfortably clammy on the inside.
Reproofing does not repair a damaged membrane. Delaminating seam tapes, tears, holes, delamination or a faulty zipper need professional repair.
When to wash, when to reproof?
| Observation | Recommended next step |
|---|---|
| Dirt, sweat or sunscreen on the fabric | Wash according to the care label |
| Water beads on the clean jacket | No new reproofing needed |
| After washing and allowed heat, water soaks evenly into the fabric | Reproof according to the product |
| Water penetrates at specific points such as a tear, seam or zipper | Have the damage inspected and repaired |
For the beading test hang the clean, dry jacket and spray the shoulders and sleeves with clean water. If round droplets form, the treatment still works. If dark, wet areas appear, a follow-up treatment may be useful.
Wash a rain jacket in seven steps
- Read the care label:Temperature, wash program, spin, dryer and ironing instructions vary by material. The label takes precedence over generic internet tips.
- Empty pockets:Remove tissues, keys and lip balm. Let heavy mud dry first and brush it off gently.
- Fasten closures:Close main and pocket zips, snap fasteners and Velcro. Loosen drawcords so the fabric is not kept under tension.
- Choose detergent:Use a mild liquid or appropriate technical detergent sparingly according to the instructions. Do not use fabric softener, bleach, stain remover salts or powder detergents with optical brighteners.
- Wash gently:Follow the programme and temperature on the label. Do not overfill the drum and choose a low spin speed unless the manufacturer specifies otherwise.
- Rinse thoroughly:An extra rinse cycle can remove detergent residue. The jacket should not feel soapy afterwards.
- Dry correctly:Air-dry or tumble dry at low temperature, but only if the label allows it. Avoid direct strong radiator heat.

Reactivate beading with heat
On suitable jackets low heat can reactivate the existing DWR. Depending on the product, manufacturers recommend a gentle tumble dryer or cautious ironing with a protective layer. Both are only permitted if the care label expressly allows it. Without such approval the jacket should remain air-dried.
After complete drying, perform the beading test again. Only if water still soaks into the face fabric across the surface is a new reproofing indicated. This sequence saves care products and prevents unnecessary treatments.
Spray or wash-in reproofing?
Spray-on reproofingis applied directly to the clean exterior. It is practical when the lining or interior should remain untreated. Spray evenly, distribute excess with a clean cloth and then dry or activate exactly according to the product instructions.
Wash-in reproofingis added to the washing machine and reaches hard-to-access areas. However, it treats more than just the face fabric. Whether this variant suits the membrane and construction is decided by the jacket's instructions.
Prefer a PFAS-free product designated for technical clothing. Use sprays outdoors or in a well-ventilated area and avoid inhaling the spray mist. A pump spray is usually easier to dose precisely than an aerosol. Manufacturer instructions on application amount, wet or dry fabric and heat activation are binding.
Avoid common care mistakes
- Fabric softener:It can leave residues and impair the beading effect.
- Too much detergent:Using more cleaner doesn't mean it's cleaner; it often leaves more residue.
- Too much heat:It can damage coatings, seam tapes and elastic parts.
- Reproofing over dirt:The product distributes unevenly and locks the dirt into the fabric.
- Treating every wetness as a defect:A fully soaked face fabric and a leaking membrane are two different problems.
How to keep the jacket ready for longer
Wash as rarely as possible, but as often as necessary. Salt from sweat, skin oils and dirt should not remain in the material for months. After use, let the jacket dry completely and store it loosely in a dry place. Constantly compressing it in a stuff sack is inadvisable.
Before a trip, besides the beading test, it's also worth checking seams, hood, drawcords and zips. After heavy rain or thunderstorms, paths and streams can also be problematic; our guide helps with thatHiking after a thunderstorm: What families should check.
Frequently Asked Questions
Can a rain jacket go in the washing machine?
Many models may be washed on a gentle cycle, but not all in the same way. The care label and manufacturer's instructions for the specific product are decisive.
Does it need to be reproofed after every wash?
Not automatically. First wash, reactivate with low heat if allowed, and then test. If water beads off, no new treatment is necessary.
Does reproofing spray make a leaking jacket waterproof again?
No. It mainly restores the water-repellent effect of the face fabric. Damage to the membrane, seams or closures must be repaired.
