IMPROVE PRODUCTIVITY BY PRE-TREATING DISCONNECT SWITCHES WITH PATENTED 1FR PENETRATING FLUID BEFORE OPERATING!Commonly used penetrating oils and cleaners are not formulated to remove corrosion and rust and do not work efficiently or quickly, leading to extended time on jobs and lost productivity. 1FR Penetrating Fluid uses CO2 as a propellant, is Non-Conductive, Non-Flammable, and Arc-Quenching. 1FR Penetrating Fluid works with chemical action called Chelation to dissolve and remove hardened corrosion, rust and worn out died grease deposits which inhibit switch movement. Customer Testing proves full operation may be achieved in as little as 30-minutes when used to pre-treat switch parts. 1FR Penetrating Fluid is formulated for corroded parts and an excellent choice for freeing disconnect switches, rusty bolts or any other metal moving part.
