R.P.
My advice is what everyone else has posted. The vinegar goes in the fabric softener dispenser and sprinkle the baking soda in with the clothes. I've been using both in my towels for almost a year now and it has eliminated the musty smells I use to get with towels that were left on my sons bedroom floor. The vinegar also acts like fabric softener. Also since I started using them my washer doesn't get the musty that sometimes front loading washers get. I buy gallon jugs of vinegar and large boxes of baking soda at Sam's Club......
