Foam-Brite's foaming power is incredible. It is a non-acidic, alkaline-based cleaner and brightener containing the best available biodegradable ingredients and a unique chelant/surfactant package to quickly penetrate and remove greasy soils and oxidation. It's high-foaming formula helps lift greasy soils out of the coil, leaving finned coils clean and bright. It can be used to replace the more dangerous HF acid-based products for condenser coil cleaning because Foam-Brite does not contain any acids.
