I get what you're saying Lee-Bee. I have usually always had a young crew and only once have I had vomit on them and once a pee accident. Other than that, it's my carpet that takes the beating!! lol

My fiance is a janitor at an elementary school and he says many of the younger classrooms have these mats too and they just mop them up every day. He has mentioned that mine have been kept much cleaner though lol....but I also obviously don't have the traffic a classroom does. This summer I will likely replace a few of them. It's still cheaper than getting my carpet cleaned though.
