CONTACLEAN efficiently removes oxide and sulphide layers from metallic contact surfaces of any kind. Simultaneously, special inhibitors ensure long-lasting lubrication and corrosion protection. Reduces contact resistance that leads to failures, and eliminates voltage drops. Durable preservation of the perfect operational reliability of all electro-mechanical contacts. CONTACLEAN has been a well-proven agent in radio and television engineering as well as in laboratory and after-sales service for a long time.
