Coil CleanerTriClean 2x coil cleaner is a specially formulated chemistry paired with convenient packaging. Designed with an integrated sprayer, simply connect to hose, clean, and rinse, says the company. This metal-safe chemistry rapidly emulsifies insulating soils from the outdoor coil, restoring system efficiency. The low-foaming, biodegradable formula revitalizes and cleans more effectively than water alone. One bottle cleans up to three 5-ton coils.
