Condensate Drain Pan Treatment 
This unique Gel formulation encompasses breakthrough technology for keeping drain pans clean and free from plugging. Once a Gel tab becomes wet from condensate, its special ingredients activate and form a gel, locking the gel tab in place. It will not move, eliminating any change at blocking the drain. The active ingredients are slowly released, providing protection for 3 months.
