Although some have said that Tide was acceptable, I've read that any kind of detergent is unsuitable for washing water repellent / breathable material. Apparently detergent leaves behind a residue that coats the DWR, rendering it useless.

My research ultimately led me to try Dri-pak soap flakes, made in the UK and resold through a distributor in the US. Results thus far have been promising. The DWR held up after the wash, and the soap lifted all of the dirt/stains. Dri-pak is a much cheaper alternative to Nikwax Tech Wash -- about 4 times cheaper per unit washed.

So, how do you wash your DWR apparel and have you tried Dripak?

This seems an awful lot like spam. I think it would be a better question if you removed all mention of that product – Rory Alsop Oct 1 '13 at 21:24
Kevin must be sponsored by Tide. Removing all mentions of the competition. – ppl Oct 1 '13 at 22:56
fwiw, basic description of DWR if you are not familiar: – Justin C Oct 2 '13 at 1:15
This wasn't spam and my post didn't require moderating. Any recommendation by anyone can be considered advertising. I mentioned 3 products- - Tide, Nikwax, and Dripak. See what admin Kevin did? – Dowwie Oct 2 '13 at 12:51
I agree that that extend of moderation shouldn't have happend - should be nothing bad about discussing specific brands or products. Dowwie, do know stackexchange sites are community moderated, and discussion around that is encouraged. – Sdry Oct 2 '13 at 13:57

I use the following video as a guide:


  • Prep garment: close all main zippers, open pockets, and loosen elastics.
  • Wash sweat/dirt/oils off using a performance washing liquid, using cold or warm water. Regular detergent is okay, rinse twice.
  • Spray garment with a DWR reproofing spray, focusing on shoulders and other high-abrasion areas.
  • Dry garment in a drier, 40 minutes on regular temperature.

They recommend Granger's wash and DWR spray. I've had really good luck with this combination.
