It does what you need it to,
Verified Purchase(What is this?)
This review is from: Nikwax Wool Wash High Performance Cleaner (Sports)
I bought this in order to wash a number of wool items I wear. I have used it on wool socks, merino wool baselayer clothing and Swanndri "felted" wool garments. The clothes are washed on a 30C wool wash and come out clean and not smelly, which is all that you can ask for. I have yet to test whether it makes a difference to the waterproof qualities of the Swanndri garments.
