"My kids are competitive XC skiers. We live in a winter wonderland. I have to buy this once a year or so to keep up with the down washing.My only complaint: It doesn't do great at getting stains out of jackets, which is annoying because my kids abuse their clothes. But it takes good care of the down so we just deal with stains.It doesn't leave a smell.This will not waterproof, that's a separate step, so don't expect that.I add it just like regular liquid laundry detergent, though pro-tip, we pre-soak our down in a bucket of water to get it wet enough beforehand. New washing machines go by weight and dry down weighs almost nothing, so pre-soak it and then it will wash better.We've used it on sleeping bags, down comforters, jackets, and any other down stuff that comes into the house."

Washed my TNF 1996 Retro Nuptse down jacket perfectly and fluffed out like new after drying with wool dryer balls. Did cause my jacket to have an odd gamy smell afterwards but nothing too strong or serious and it seemed to clear out after a few wears. But that could’ve been caused by the dryer balls, they may have had a little bit of lanolin still in them, but the detergent also had a weird Sheepy smell to it. Very slight.randy

I hand washed a down vest I got used - one oz Nikwax wash in a large 1gal mixing bowl. The vest had some serious BO from the previous wearer. The Nikwax wash completely removed the BO, and the vest appears and feels much better than the condition I received it in. While I could smell the Nikwax wash while I was doing the washing, there is no odor after rinsing.What Customers Talk About
