Baking Soda use #1964

It's my fault for not folding the clothes right away but my daughter could have told me that the clothes she pulled out of the dryer were still damp, right? So they developed that lovely mildew-y smell. So I had to re-wash them with about a 1/2 cup of baking soda to get the smell out. This isn't the first time this has happened, using laundry soap alone does not rid the clothes of the smell.
