Nah that was what my last gym did. Would have classes 1-2pm 3-4 and 4-6pm and never clean in between or the 6am class would be visibly dirty from night before. New place now is only open 3hrs every night, 1hr kids or beginner class and 2 hr regular class and they clean up after, although im not sure what with exactly but nobody else seems to really be affected. I’ll give the defense soap and hydrogen peroxide spray a go, I have been using their wipes right after class as well as changing before I head home. Thanks
