So I got my box of econuts soap nuts this week and I've been using them with great success! I can't believe they work so well, my clothes are getting really clean, I even washed some old shoes and they came out looking brand new. You just put a few into this little cotton satchel and then take them out before you put them in the dryer. You can reuse them 10 times! The only issue I had was when I lost my nuts during a load of wash. I searched and searched through every bit of laundry, and eventually discovered my nuts were in the leg of my pants! Hahaha! I was in stitches telling my husband about it.
