Make your own disinfectant cleaner with a 50-50 water vinegar solution. If you’d like, you can add a few drops of essential oils.
Generously spray your mixture onto your mat, and scrub with the soft side of the sponge. Leave flat to air dry.
As much as possible, avoid getting oily substances on your mat. In case of grease stains, wash with your vinegar solution.
To store your mat, roll it up and keep it protected from moisture and sun exposure.
