I was super excited to try this product, but in the end it really just didn’t impress me. 
The process is much more involved than I’d like, and if you follow the package instructions takes at least a day and a half to actually use because you have to let it sit in the washer twice for hours at a time.
The end results weren’t noticeable to the eye, though I’m sure it cleaned some invisible bacteria. I don’t think I’ll even bother using the rest of the pack to be honest.
