Wash a Dirty Yoga Mat
Follow the manufacturer's directions. Since not all mats are made from the same materials, you will want to wash your mat according to the directions provided. If you have lost the cleaning instructions, stick to a nonabrasive cleaning process.
Decide just how dirty your mat really is. If all you need is a light cleaning, then you should create a solution of baking soda and water. Use a tsp. of baking soda to about two cups of warm water. Use a soft cloth to clean the dirty areas of your mat. Rinse the mat with clean water and dry with another cloth.
Deep clean your yoga mat by soaking it a tub of water. Use a kitchen sponge to scrub off the dirty spots. Avoid using detergents, as they will cause your mat to be slippery during use. A baking soda and water solution can be used for extremely dirty spots.
Dry your mat by rolling it with a towel (or two as you need to cover the length of the mat) and letting it rest overnight. In the morning, unroll your mat and hang it to finish drying.
Keep your mat clean by using a spray bottle of warm water or natural yoga mat wipes after each workout. Do not use alcohol based wipes on your mat.
Keep a few yoga mat wipes in your bag to do a quick clean before and after your workout. With basic maintenance, you should not have to do heavier cleanings very often.
