Electrical Contact Cleaners are used for cleaning electrical contacts in panels, motors and other fittings.
The contact cleaner consists of a cleaner such as isopropyl alcohol contained in a spray-container. The Electrical Contact Cleaner can remove impurities such as oil, grease, etc. The jet of air is used to remove deposits.
Contact Cleaners using Carbon Tetra Chloride were widely used until a few years back. However, today, contact cleaners no longer use Carbon Tetra Chloride as it is considered to be detrimental to the ozone layer.
