Used this on a red waterproof jacket that had seen better days. The collar, cuffs and around the bottom were very grubby. I was thinking of throwing it away but the assistant suggested trying this wash first.
Result was excellent. The jacket looks like new. Well worth the purchase price.
I'm trying it again on a couple of cheaper jackets that just smell terrible, they were left folded up in a bag but still damp - hopefully the result will be just as good!
