brilliant- VERY CLEVER .. Take your favorite liquid fabric softener and soak an old hand towel or flour cloth completely with it. Wring it out and let it dry completely, then throw it in with your next load. This mega-fabric softener sheet should be good for at least 40 loads of laundry, stretching out softener use and lessening waste.
Over time, towels build up detergent and fabric softener, leaving them unable to absorb as much water and smelly. Recharge them by washing them once with hot water and 1cup vinegar, then a 2nd time with hot water and half cup baking soda. This strips the residue and leaves them fresh and able to absorb more water again. Works like a charm!
