1.   CRC 2-26 CRC Electrical Parts Cleaner is a quick-drying, non-chlorinated evaporating parts cleaner for use on electric motors and other heavy-duty electrical and mechanical equipment. It swiftly and effectively degreases, removes oil, dirt, wax and other foreign matter that are common causes of current leakages and electric inefficiencies. FEATURES :   Cleans, lubricates, protects, penetrates, and loosens corrosion.     Prevents corrosion by displacing moisture.    Restores resistance values by reducing current leakage.     Provides precision lubrication by its thin, high dielectric strength, lubricating film   Helps restore water-damaged electrical equipment.    Frees rusted or seized parts by penetrating under dirt and scale into the finest       pores and cracks.   Can be used on all metals and alloys.    Will not harm modern plastics, painted surfaces, coatings and rubbers   Convenient 360° (upside-down) spray valve for aerosol.
