NikwaxWOOL WASH High-Performance Cleaner and Conditioner for Woollen Base Layers. Cleans, Softens, Enhances Wicking, Freshens Wool, Merino Merinowool Sports Clothing and Accelerates Drying

I've been very impressed with the Nikwax wool wash. It washes wool garments well and leaves them smelling fresh and feeling soft.It's expensive, but I feel it's worth it for washing expensive Merino wool clothing.

Seems to clean the woolen items and leave them smelling fresh.The user instructions don't confirm the number of items per wash. The instructions just say items.1 litre should last a long time and is value for money

Seems to be effective as a ‘gentle’ way of washing merino base layers.

The smell canput some people off , but , cleans and protects wool ,without removing it's natural oils , you only need a small amount for a good clean .

It’s nikwax, it works, it’s decent

I've been using this stuff for years with my merino wool items of clothing, including socks and cold-weather base layers. It seems to keep the items more flexible and softer than standard non-bio products. Definitely recommended.

Seems to work well on performance wear, not as well on wool sweaters. There's a lingering smell of chemicals left after the wash, which I find unpleasant, so I needed to hang them in the outdoor shed for a few days to air out. But they're definitely clean with no armpit odor.

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.
