StayClean tablets are an affordable, easy-to-use treatment for condensate trays. The tablets control odor and prevent the buildup of sludge and blockages in the condensate tray and drain. They are safe to use, non-corrosive, and fully soluble, meaning they leave no residues that could cause further problems. One tablet treats a 2-3 kW system and lasts up to 8 weeks. Multiple tablets can be used in larger systems for maximum flexibility.
