Why DWR Matters: Restore Your Jacket’s Water Repellency

Durable Water Repellent (DWR) makes raindrops bead off your shell. Sweat, dirt, and detergent kill it. Here’s how to bring it back—eco-friendly.

3-Step Revival

1. Wash: technical detergent at 30 °C (Grangers Performance Wash).
2. Treat: spray Grangers Repel Plus Eco on shoulders & sleeves.
3. Activate: tumble-dry 15 min low or warm iron through cloth.

Don’t Do This

• No fabric softener—clogs pores.
• No high heat—membrane delamination.
• No cheap silicone sprays—one-day effect.
