I use it about 75% of the time...other times I use Trader Joe's laundry soap...once in a blue moon RLR, although I am not sure what it does that sportwash doesn't do. I really like Sportwash for Ds' clothing and use ut 100% of the time. They come out soft w/ no fabric softener necessary.
I use only Sportwash on my CFS. I do about 24 dipes a load, and use about 1.2 a capful. I do a cold rinse, with baking soda, followid by a hot wash with the Sportwash, and add a Doney ball with TTO for the rinse.
I am very happy with the way my dipes come out of the laundry!
