One of the questions I get asked most often is, "How do you clean your yoga mat?" It's simple for me: I would never put anything on my yoga mat that I wouldn't want on my face. After all, I rest my face on my mat often!
I use organic ingredients, always make sure my mat is dry before rolling or storing it to prevent mildew and odor, and use this quick and easy cleaning technique, New York City-space-confines-approved.
One more thing to consider: Wash your feet before you get on your mat. Unless you want what's all over your feet to get on your face, wipe them down! Try it out! Happy, clean practicing!
