As with above, when mats have been left rolled up in their packaging ever since they were made in the factory, they can sometimes smell of rubber. The best way to counteract this is to wipe the mat down with warm water. We then suggest making a mixture of tea tree oil and lavender and spraying it over both sides of the mat after the first clean. After drying, this should get rid of the rubber smell and leave your mat with a gentle, soothing fragrance, which will be great for when your face is pressed into the yoga mat.
