I like Odoban. It is organic and kills bacteria, fungus, MRSA causing agents, staff, and a ton of other unwanted grossness.I use hot water, mop with a anti microbal mop head, then dry mop with a different mop head. It keeps our mats clean and safe, we have never had a problem with our mats. This with 12-14 classes a week. We mop before each class.
