Oh I wasn't being fanatical I was simply sharing the fact. Studies have shown that wrestling mats and several other surfaces can indeed transmit tinea. Its been rehashed here by a few other people. Im not saying that the transmission from the mat is a major cause or that it even happens on a regualar basis, but it certainly never hurts just to make sure your mats get cleaned. By the way the sweat that comes from your kids as they roll around on the mat, from their shirts, kneepads, etc etc. That is all the moisture you need to start the spreading. Also if you are in a hot room with high humidity although you may not see actual moisture droplets on the mat it is still there. Its the same principal as when you go out to your car in the morning and there is a thin layer of frost on the windshield, the moisture is in the air and on the surface, the coldness of the surface causes the moisture to frost. All in all as a former coach and as a person who's been around wrestling for 14 years now, I encourage coaches to clean their mats both before and after practice every day.
