Lennox 19P42 – DiversiTech Pro-Red+ Extra Heavy-Duty Outdoor Coil Cleaner is a professional-grade, fast-acting cleaning solution designed for condensers, microchannel coils, and mini-split systems. This high-performance formula delivers powerful cleaning results without the risks associated with traditional acid-based cleaners.

Pro-Red+ features a non-acid, heavy-foaming formulation that penetrates deep into coil surfaces, lifting away stubborn dirt, grease, tarnish, and corrosion. Its vigorous foaming action eliminates the need for prolonged soaking, steam cleaning, or aggressive scrubbing, helping technicians clean coils more efficiently while protecting system components. Unlike conventional acid cleaners, Pro-Red+ does not emit corrosive fumes and will not rust ferrous metals, making it safer for both equipment and users.

This biodegradable coil cleaner is NSF approved and engineered to clean and brighten outdoor HVAC coils while restoring heat transfer efficiency and overall system performance. Packaged in a convenient 1-gallon jug, it is ideal for routine maintenance and heavy-duty service applications in residential and light commercial HVAC systems.
