Product review (4 stars): My clothes last longer! 
I bought this to extend the life of my light colored  clothes. We have untreated well water with a high iron content that makes our tubs, toilets, even the inside of the washing machine orange. The orange permanently discolors light colors. I don't care if we have discolored sheets or towels, but I do care when it comes to ruining my clothes. I buy a few gallons of water at the grocery store and wash my light colored clothes with my Wonder Wash. I use my washing machine's drain & spin cycle to spin the excess water out of my clothes. I like that I don't have ruined clothes anymore.
