Special HD CalClean is an extra-strong liquid detergent containing surface-active agents, grease solvents, alkaline cleaners, corrosion inhibitors, and water conditioners specifically designed for cleaning electronic air filters. Electronic air filters can become coated with tobacco tars and other deposits that are very difficult to remove with ordinary detergents. HD CalClean will rapidly clean dirt, grease, dust and tars from the plates on these filters and, it will not corrode or tarnish aluminum or other metals when used at the recommended concentrations.

The product is easy to use-just spray it on. HD CalClean quickly reacts with caked-on greasy dirt and smoke tar residues, loosening them and making them water soluble and easy to rinse off. Dirt and grease are flushed away effortlessly with an ordinary hose. If no water connection is available, fresh water may be sprayed on with any of the Nu-Calgon sprayers. Equipment will be left clean and ready to operate at top efficiency.
