I give my mats a "quick bath" every now and then to help keep it from getting dry and crackly. I use warm water with a bit of Dawn in it, and wipe gently with a soft rag, rinse, dry with a towel. I then let it air dry too. My bigger mats I bathe in the tub. My mats have lasted for quite a long time, and I do use them lots! Hope this helps!! :)
