Evaporation rate - Since there isn't opportunity to wipe the solvent off the inner parts of the electrical device, fast evaporation is very helpful.Flammability - If there is risk of flames or sparks, a nonflammable solvent is recommended.Solvency / cleaning strength - The solvent cleaner needs to be strong enough to dissolve oil and other contamination.Breaking down in this sense is described as a failure of insulating properties, where the electricity breaks free of the conductors and burns a path through the weakest area of the insulating materials. Dielectric strength is defined as the maximum electric field that the material can withstand under ideal conditions without breaking down. Dielectric strength - If you are cleaning energized (powered) equipment, use a cleaning solvent with a dielectric strength of 30 kV (30,000V) or higher.Spray force - Aerosol cleaners are generally used to penetrate into the tight areas around the contact and provide agitation.Other solvent cleaners an be used, but be aware or the following factors: We recommend choosing a solvent engineered specifically for contact cleaning. Available in spray can and bulk packaging.Safer solvents - do not contain TCE, nPB or Perc.Powerful cleaners - grease and oil flow right off. Our contact cleaners remove oxidation, oil, and other contaminants from contacts, metal switches, motors, relays, generators, edge connectors, buss bars, circuit breakers, scales, and sensors.Īdvantages of Techspray contact cleaners: Techspray offers a wide variety of electrical contact cleaners in spray and bulk packaging. Contact cleaning solvents usually come in pressurized aerosol packaging for convenience and to provide a forceful spray that creates agitation and reaches into all the crevices of the connectors. The goal is to quickly remove insulative contamination as quickly as possible, avoiding extensive wiping and scrubbing if possible. Soldering Iron Tips for Hexacon, American Beauty, and Other Stationsīlast Oil, Carbon Deposits & Other Contamination Off Electrical ContactsĪ contact cleaner (also called electrical cleaner, switch cleaner, electrical contact cleaner, and, specific for automotive repair, battery terminal cleaner) is a solvent cleaner designed to remove contamination from electrical contacts, the conductive surfaces of connectors, switches and other electrical and electronic components with moving surface contacts.
