If you have lost the manufacturer’s directions or are not sure who made your yoga mat, here’s a primer from Yogi Chetan Mahesh, founder of Association for Yoga and Meditation:
If your mat is lightly soiled, use a spray bottle, damp sponge, or terry cloth scrap to apply a solution of two cups of water and four drops of dish soap. Rub the soiled areas. Inundate the mat with clean water; then rub with a dry terry cloth towel. Hang to air dry.
If your mat is heavily soiled, inundate it in a solution of warm water and mild detergent; use very little soap as any residue may cause the mat to become slippery throughout future use. Thoroughly hand wash the mat and rinse in clean water. After squeezing out the excess water, put the mat on a dry towel and roll the mat and towel together. Stepping on the rolled up mat will compress more moisture out of the mat and into the towel. Then unroll and hang to air dry.
