Once you are finish with the mat, simple wash and put it away for next time use. I am extremely happy with these mats, and look forward to grilling all the time. One of the things that I hate the most is actually cleaning my grill, when I am done cooking, so this is an added plus, now I can go to any park and use their grills and not worry about the germs and so forth that the grill came in contact before me.
