I put my yoga mat in the back of my car in the direct sun when I cleared my back seat. Forgot to move it again and now after days of 100 degree weather there are parts of my mat that almost look burnt and are dried out. Is there a way to rehydrate my mat and save it? It was a fairly expensive mat so I really hope there is a solution. I am considering soaking it in a tub of warm water and I feel like using some organic oils on it might help. Ideas?
