Steps
Look for water soaking into the outer fabric instead of beading. That wetting out means the DWR needs refreshing.
Wash the jacket or bag with a dedicated technical down wash, not regular detergent. Dirt and oils stop new DWR from bonding.
Apply a spray-on or wash-in DWR made for down gear, following the product label. Use the dose and water temperature it states.
If using a spray, give extra coverage to the shoulders, hood and other high-wear areas. These take the most rain and pack strap rub.
Dry the item as the care label allows, using low heat to activate the DWR. Modern treatments often need heat to start repelling water.
Let the gear cool, then flick a few water drops onto the surface. Beading means the treatment is working. Patchy soaking means reapply as the product allows.
Tips and common mistakes
Never use standard detergent or fabric softener because residues can stop DWR from bonding.
Check the care label before drying, since too much heat can damage nylon fabrics.
Spray shoulders and hood more heavily than the rest of the jacket.
Reapply when water stops beading and the fabric starts to soak through.
Questions
Can I skip the wash and just spray on more DWR?
No. DWR bonds poorly to dirt and oils, so clean the item with technical wash first.
How do I know the DWR is activated?
Water should bead and roll off the surface after drying. If patches soak in, apply more treatment and dry again as the label allows.
Can I use regular detergent if I rinse well?
It is not recommended. Use a dedicated technical wash so residues do not block the new DWR.
