This is a great prduct from Nordstrom and I've used it for my fine washables for years. There are two scents, lavendar and the classic pink. To me, I like both, so the choice is really just personal preference.
When I use it, I just throw my hand washables in a laundry bucket with water, swirl in a cap or two and let things sit for a couple hours. Then rinse and hang dry. I've never used it in a machine, but I do think this is possible as it doesn't have a high suds factor. My fine washables smell great and they always seem clean after using this wash.
I highly recommend it as a staple addition to your laundry room.
