Every time i wash my bath towels they have a nasty smell when i use them. what do i use???

Wash them with your soap plus 1 cup of baking soda.Use hot water too. If you can dry them out on a clothes line in the sun that will help too. Always make sure they are thoroughly dry when you put them away. You could also put a box of baking soda in your linen closest.Every time i wash my bath towels they have a nasty smell when i use them. what do i use???
Tide. It is about the only product left on the market that will actually clean laundry. The other stuff just does not work any more.Every time i wash my bath towels they have a nasty smell when i use them. what do i use???
Your dryer is probably not drying them completely and they are mildewing. Try drying them longer or twice.
Maybe your washing too many at a time,mine smell when my hubby puts too many in a load.Or maybe, where you store them doesn't get any ';air'; so they end up musty?
Wash them in warm water, put in the dryer immediately, and make sure they dry completely. If they sit around too long, they get musty smelling. I don't like to use fabric softener for my towels as it decreases the absorbency. However, you may want to use a little bit the first time or two to help eradicate the smell that is lingering. After the next wash or 2, they shouldn't smell anymore.
try using a little bleach very little.
Try using a fabric softener (personally, I like Purex's After the Rain) in the rinse cycle and make sure you clean the lint trap on your dryer for proper drying.
