Fill cap with approximately 30mls (a teaspoon is about 5mls) of cleanser and add to 4 litres of water in a bathtub. Soak mat 5-10 minutes in solution, periodically moving mat around. Rinse mat thoroughly with fresh water, squeeze out excess water and hang outside away from direct sunlight until mat is completely dry. It will depend how often you practice on your mat and how much sweat you generate as to how often you should deep cleanse it. If you clean it after every use then a deep clean will only be required periodically.
For a quick daily clean, use with our Everyday Yoga Mat Cleanser to prevent buildup and extend the life of your mat.
