Nu-Calgon 4291-08 Nu-Brite Alkaline Based Coil Cleaner, 1 Gallon, Non-Acid HVAC Evaporator & Condenser Cleaner

When selecting a coil cleaner, choose a non-acid, alkaline-based solution designed for effective outdoor coil cleaning. This alkaline-based cleaner is formulated for cleaning and brightening air-cooled condenser coils. It uses advanced foaming detergents and chelating agents to rapidly penetrate, dissolve, and lift greasy dirt and grime, pushing contaminants out of the coil. It provides the cleaning power typically associated with acidic products, without the risks and hazards of acid-based cleaners. Designed for cleaning and brightening air-cooled condensers and other finned heating and cooling coils located outdoors. This alkaline cleaner delivers strong performance while offering a safer alternative for technicians and equipment. Its high-performance surfactants quickly penetrate layers of oily buildup and deposits. The foaming action drives loosened debris out of hard-to-reach coil areas, helping restore equipment to peak operating efficiency. This product is not recommended for indoor use. Available in multiple packaging and concentration options, including traditional ready-to-use solutions and concentrated formats designed to reduce storage space, weight, and handling effort. Concentrated versions allow flexible dilution based on application needs and help minimize spills and waste during transport and use. Directions This product must be used in accordance with the following directions by HVACR professionals only. Use only on condenser coils or other finned coils that are located outdoors.Wear protective equipment including goggles, gloves, and appropriate garments during use.Ensure the system is powered off before application.Prepare the cleaning solution by mixing one part cleaner with three to four parts water, unless using a pre-diluted or concentrate-specific delivery system.Add water to the sprayer first, then add the cleaner.Apply using a professional-grade sprayer.Spray onto dirty coils or surfaces and allow the solution to remain in contact for 5–10 minutes.Rinse thoroughly with water after cleaning.Return the system to service once cleaning is complete.After use, thoroughly rinse the sprayer, wand, and nozzle with clean water.
