Flushes for air conditioning units clean out dirt and other blockages from compressors to improve overall performance. They increase the flow of air, cooling refrigerants, and oil that lubricates the compressor. Flushes are normally done on AC units when the system is opened for repair or a part is replaced to ensure no foreign objects have entered the system.

Salt flushes dissolve and remove salt and debris that cause corrosion on marine vehicles, heavy-duty RV and truck engines, electrical equipment stored near fresh or saltwater, and tools kept outdoors. When flushed through a vehicle engine, these cleaners place a protective coating on metal components to withstand prolonged use in water.

Flushes for radiators remove outdated antifreeze, road debris particles, rust, and chemical contaminants that may have leaked in. They replace and refresh the coolant in radiators to help ensure the engine runs efficiently and to protect metal parts from corrosion.
