Learn how to restore DWR on your shell and insulation garments with a wash-in water repellent like OrganoTex Wash-In. Step-by-step instructions for a lasting reproof.

Quick answer

Use a wash-in water repellent like OrganoTex Wash-In to restore DWR on your shell and insulation garments when water stops beading on the surface. It's a simple soak-and-dry process that revives water repellency without a spray bottle.

When to reproof vs. when to wash only

If your jacket still feels dry inside but the outer fabric wets out (absorbs water instead of beading), the DWR is worn. A wash-in treatment restores that beading effect. If the fabric is just dirty or smelly, a regular wash with a tech wash is enough — reproofing can wait.

Why wash-in works for most gear

Wash-in repellents coat every fiber during the rinse cycle, reaching seams and areas a spray might miss. They are ideal for jackets, pants, and insulated pieces with complex baffles. The trade-off: you need to dry-activate the treatment with heat (tumble dryer or iron), and the bottle treats multiple items, so the upfront cost is higher than a single-use spray.

Step-by-step wash-in reproofing process

1. Clean the garment first: Wash your gear with a tech wash (not regular detergent) to remove dirt and oils. Rinse thoroughly. A clean surface lets the repellent bond evenly. Skipping this step can cause patchy beading — the repellent won't stick to dirty fabric.
2. Add the wash-in repellent to the rinse cycle: Pour the recommended amount of OrganoTex Wash-In (check the bottle for your load size) into the detergent dispenser or directly into the drum. Run a rinse-only cycle with warm water (30-40°C / 86-104°F). Do not add fabric softener. Too much repellent can leave a sticky residue; too little won't restore full beading. Measure carefully.
3. Remove excess water gently: Take the garment out and gently squeeze (do not wring) to remove excess water. A spin cycle on low is fine, but avoid high-speed spins that can force the repellent out unevenly. Wringing can damage the membrane or insulation — always squeeze or spin low.
4. Heat-activate the DWR: Tumble dry on medium heat (or low if your garment care label says so) for 20-30 minutes, or until fully dry. For items that cannot go in the dryer, use a household iron on a low setting (no steam) with a cloth between the iron and the fabric. Heat is essential — without it, the repellent won't cure and water will not bead. Check the care label first.
5. Test and repeat if needed: Sprinkle a few drops of water on the fabric. If they bead up and roll off, the treatment worked. If they soak in, repeat steps 2-4 with a fresh dose of repellent. Heavily worn gear may need two treatments. Wait 24 hours between applications for best results.
