My wife's uncle has had a blue non slip resin floor laid around the outside of his indoor swimming pool. And its a nightmare to clean. They do not use chlorine in the pool. So what would the best chemical cleaner to use? it has gone a slight brown color and they want to get it back blue again..it only 6 months old. The company who laid the floor came and scrubbed a small area and it came up ok..he just used water and it took him ages to do a square foot...So any ideas please. Thanks
