Contact cleaner

Contact cleaner, also known as switch-cleaner[citation needed], is any of various chemicals, or mixtures of chemicals, intended to remove or prevent the build-up of oxides or other unwanted substances on the conductive surfaces of connectors, switches, and other electronic components with moving surface-contacts, and thus reduce the contact resistance encountered.[1][2][3] The use of contact cleaner can help to minimize the wetting current across a pair of contacts.[4]

An example of a simple contact cleaner is isopropyl alcohol[5][2]

Some contact cleaners are designed to evaporate completely and rapidly, leaving no residue.[6][7] Others may contain lubricants.[8][9] Lubricants themselves should not necessarily be used as contact cleaners, especially if they are designed to leave an unsuitable residue.[10] However, appropriate lubricants may work well as contact cleaners.[11]
