I've read about this on the Dave Ramsey forums, and some of the frugal money websites I've participated on, but I haven't actually gotten around to trying it yet. Why? Because you need a 5 gallon bucket, and I dont have one, or the space to store one. PLUS, using coupons, I'm stocked up on laundry detergent at least for another year.
Nonetheless, I wanted to post a link to this story because I believe it's got alot of truth to it. They have a point - how did people in the olllllld days clean their clothes? Here's an idea - with WATER. If you like the smell of laundry detergent, this may not be the best option for you though.
