Good in the washing machine.,
Verified Purchase(What is this?)
This review is from: Nikwax Cotton Proof Waterproofer For Cotton/Canvas (Sports)
I used Nikwax cleaner in the washing machine to clean two non water proof cotton jackets. The jackets did not need to be dried before going through the machine again. This time using the Nikwax Cotton Proofer.
I can now be out in quite heavy rain for over an hour before water starts to find it's way through.
