Wash your towels in hot water with a cup of vinegar, and then run again in hot water with a half-cup of baking soda. That will strip your towels from all of that residue and mildew smell and will actually leave them feeling fluffy and smelling fresh. ***Do not add laundry detergent to either wash. Just once with vinegar and once with baking soda. *** This trick also works well with wet bathing suits that were left to dry.
The Pinterest Project: DIY Front Loader Washing Machine Cleaner Use about 2 c. of white vinegar, split between the detergent dispenser of your machine and the rest into the basin. Turn the washing machine on to the "clean washer" setting. After that is done, sprinkle about 1/2 c. baking soda in the basin and run a regular wash cycle with hot water.
