Electrical contact cleaner cleans, lubricates, and protects electrical contacts from corrosion, and is safe on most plastics. Cleaning action quickly removes greases, dust, and oxidation, restores and maintains precision and efficiency to the instrument and component. Includes extension tube for pinpointing application. USDA Approved. Electrical contact cleaner-LV (low voc) meets or exceeds California VOC limits. This fast drying formulation leaves no residue and is compatible with component plastics and painted surfaces if overspray occurs. This next generation product contains no CFC's, HCFC's, or other ozone depleters. Blasting spray easily cleans oil, flux, dirt, and other contaminants from contacts, printed circuit boards, switches, motors, precision instruments and more. While advanced in performance and ozone safety, this product is flammable and must therefore be used only on de-energized components and equipment. Always allow to dry and evacuate fumes before power is returned.
