The best way to clean those is with a dry vapor machine. Those mats need to be sanitized as well as cleaned. It is easy to do assuming you have a dry vapor machine. Just put a cloth or small towel over the floor tool and run it over the floor. It will clean the floor as it sanitizes it. You probably won't need any chems. You will have to change the cloth as you go. We use bar towels. Cheap and we buy them at Sams Club 24 for like $10 bucks. and you can wash them over and over. We have done several of Martial arts places and they came out great. Ended up selling one of our customers a machine, when he told us he had found something similar on ebay. Now he does it himself one a week, just for sanitation reasons and to help keep it looking clean.
