My BJJ gym wipes/cleans mats at the end of the day after all classes, but there's a children's class right before the adult class and the mats do not get cleaned in between. I feel like this could be as serious oversight when it comes to hygiene because I don't imagine kids are particularly clean. I've already gotten 2 skin infections that made me look like I have the plague and I don't want another. Is this unreasonable to ask for? Do gyms typically wipe between each class even if they're right after each-other?
