When choosing a coil cleaner, reach for the BLUE!

Nu-Brite is a non-acid, alkaline-based product for cleaning and brightening air cooled condensers. It is formulated with the best available foaming detergents and chelants to quickly penetrate and dissolve greasy dirt and grime and foam it right out of the coil. The safer alternative to acids.

For cleaning and brightening air cooled condensers and other finned heating and cooling coils located outside. It is an alkaline based cleaner that does all that an acid will do without the danger of an acid. Nu-Brite’s state-of-the-art surfactants and cleaners instantly penetrate and lift layers of oily grime and corrosive deposits from the coil. Its foaming action pushes this loosened debris out of hard-to-reach areas restoring equipment to peak efficiency. It is not recommended for indoor use.

Nu-Brite 4X is a new concentrate version available in a ready-to-use quart bottle. One concentrate quart equals one gallon traditional Nu-Brite (at 4:1 dilution use). Nu-Brite 4X takes less space on truck, is easy to carry on roofs, and has cleaner connecting – no more pouring or spilling. The specially developed packaging has a dilution insert assembly; simply use what is needed, cap bottle and use for another job. The product ships as a limited quantity –easier to get to the job site. Nu-Brite 4x requires the Clean Connect Sprayer.
