I've really been enjoying the Purex Crystals for the washing machine. (I think it's called a "laundry enhancer" LOL).
My husband uses (over-uses!!!) liquid Downy on his clothes, but I'm not a fan. The Purex Crystals are great, though - easy to use, no grease spots on the clothes, and a really nice scent that lasts a while.
And, so far anyway, don't seem to make me break out or cause other issues.
I tried the Downy Unstoppables, but they don't work as well for me (didn't always dissolve as they should have, for starters).
