Over time, towels build up detergent and fabric softener, leaving them unable to absorb as much water and smelling funky. Recharge them by washing them once with hot water and one cup vinegar, then a second 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!
