DWR is reactivated after a standard wash dry cycle. Once the garment is dry, we recommend an extra 20 minutes of tumble-drying to fully revitalize the DWR treatment. DWR is not permanent and if a garment wets out quickly after being reactivated, it’s time to restore it.
When drying the garment no longer revitalizes DWR, it’s time to restore. When the factory-applied DWR treatment needs to be restored, apply a new DWR treatment available as a pump-spray or wash-in product to the garment’s outer fabric. A spray-on DWR is easy to use and more efficient. After washing the garment, shake to remove excess water, close all pockets and hang, preferably in an open area. Spray the new treatment evenly onto the wet face-fabric. Toss garment into a tumble dryer on a medium heat setting for 40 to 50 minutes. Now you can reactivate the DWR until you notice it needs to be restored again.
CAN I USE AN AEROSOL DWR SPRAY TO REPLENISH THE DWR?
We recommend pump-action sprays instead of aerosol sprays to reduce the environmental impact. However, technically an aerosol spray can be used.
