You can use this method on all three types of Gurugrid mats
Mix 250 ml of water + 1 tbsp. of vinegar + 10 drops of Tea Tree Oil in a spritz bottle.
Spray and gently wipe with a face cloth or bath mitt before and after each yoga session.
This may seem cumbersome, but it will soon become routine and you will be amazed at how much dirt your mat can accumulate.
Let your Gurugrid dry for several hours by hanging over a bannister. Roll up and store. Please keep your Gurugrid out of extreme heat, like in a hot car.
