Cal-Blast is a high performance aerosol with excellent solvency and blasting spray, to powerfully separate undesirable materials from the surface, offering maximum cleaning of finned coils.

Cal-Blast condenser coil cleaner quickly dissolves those stubborn, resistive deposits and oils that are found to plug coils, particularly those located in kitchens. It contains a quick-drying solvent with a pleasant scent! The high dielectric strength and non-flammable formula in Cal-Blast is great for most applications and will not short out electrical equipment.

Due to its volatile organic compound content, this product is prohibited for sale by Nu-Calgon into California.
