At first, you attend yoga class and does not matter which mat is clean or not. And then you may wanna have mat which is specific to you. Then maybe one day it does not seem clean enough which you have. At that point i can help you:) I wanna share how to prepare yoga mat cleaning solution. You need a spray bottle especially glass one. Cause oils are used is lead to degradation of plastics.
1 cup distilled water 1/4 cup white vinegar 15 drops Melaleuca essential oil is used to kill bacterias, viruses or fungi on mat. 10 drops of another essential oil which has antibacterial properties. Choose of one of them. Lavender, Eucalyptus or Lemongrass
Mix together all of the above ingredients and pour into spray bottle. Shake the bottle before each use and then can spray yoga mat immediately after you finish your practice.
Place the top on the spray bottle and shake to combine the ingredients. Wipe the mat down both of each side with a clean cloth or towel. Hang mat to dry.
