The Nu-Calgon 4291-08 Liquid Nu-Brite is a high-performance alkaline-based condenser coil cleaner specifically formulated for air-cooled HVAC systems. Designed to aggressively remove dirt, grease, grime, and oxidation from aluminum fins and surfaces, this heavy-duty cleaner restores system efficiency and airflow. It’s ideal for use on outdoor coils in commercial, industrial, and residential applications.

Liquid Nu-Brite is a non-acid, biodegradable solution that provides the same cleaning power as acid-based products without the safety hazards. Its rich foaming action penetrates deep into coils and flushes out embedded contaminants when rinsed, improving heat transfer and lowering head pressure. Each 1-gallon container is a concentrate that can make up to 10 gallons of ready-to-use cleaner, providing excellent value for routine HVAC maintenance.
