The WD-40 Specialist Contact Cleaner effectively eliminates dirt, dust, oil, and flux residue from sensitive electrical parts and devices. This cleaner dries rapidly and is non-conductive, ensuring the swift removal of usual surface pollutants that might lead to current leaks, corrosion, or part failures, and does not leave any residue. It is ideal and safe for use on circuit boards, controls, battery terminals, switches, spark plugs, precision tools, power tools, and electric panels, helping to maintain your equipment in excellent condition.
