How does an electrical contact cleaner work?

An electrical contact can be at risk from the atmosphere around us when combining with oxygen to form metal oxides. This can cause issues as oxides aren’t as conductive as the base metal and can, therefore, reduce their effectiveness. The main purpose of contact cleaners is to remove oxidation and prevent this from occurring. In damp conditions, contact cleaner can also chase away condensation so that your electrical components remain effective.
