Nu-Calgon 4290-75 Nu-Blast

A “no rinse required” condenser coil cleaner in a convenient aerosol package. Double action of high pressure blast and solvent cleaning restores design efficiency of condenser coils quickly and easily. It is non-flammable and non-conductive with no rinse required, as the cleaning solvent evaporates completely.

This high performance aerosol product offers maximum cleaning of condenser coils. The high solvency formula and blasting nozzle powerfully separates the undesirable materials from the surface.
Only use with adequate ventilation.
