Freshen Your Apparel
You can easily and cheaply eliminate that yucky workout wear odor. My hack to getting rid of odors and keeping the fabric soft on my clothing is by adding half a cup of Baking soda into the washing machine when I add the detergent.
If you want to go one step further by taking care of your apparel and make it last longer here are a few more I recommend:
Set the washing machine to gentle or hand wash
Use a laundry garment bag for bras and bodysuits
Always hang dry
