Jun 1, 2012 - homemade laundry detergent. I've made this myself now, thanks to @Dacia Wells, and can highly recommend. We love the lemon smell and it gets Matt's super stinky, dirty sports clothes perfectly clean. one bar Fels Naptha, 1 box Borax, one box Super Washing Soda. All parts were found in the laundry isle at walmart and can be purchased for around $9 and can make enough detergent to last us about half of a year.
