I picked up (who knows why, because of the cute bottle I think), a new bottle of "Clorox Washing Machine Cleaner". I think it's meant for HE only...but can't tell. It's exactly three uses, which means it's exactly three cups--says to add to the bleach dispenser. I think I just spent $2.99 on 3 cups of bleach! Thoughts? Anyone used it? Is it just bleach?
