Alu-Best (Product of Indian) is a concentrated, acid based, high-foaming outdoor condenser cleaner and brightener. It effectively foams away stubborn, “baked on” lint, smoke film, insects, feathers, grass, leaves and other deposits from air cooled condenser coils. The expanding foam pushes contamination out of the condenser cleaner and is easily rinsed away with water. In addition to removing contaminants, the Alu-Best formula effectively restores efficiency and reduces operating cost by removing hidden oxidation from the condenser cleaner surfaces.
