In addition, some nonflammable cleaners that contain toxic materials such as perchloroethylene, trichloroethylene or n-propyl bromide (discussed below).
Nonflammable contact cleaners can avoid some of these safety issues, but usually at a premium price. They are generally economical and effective cleaners, but can pose a safety hazard without proper ventilation, especially if there are open flames, sparks (e.g., welding process), or hot surfaces nearby. While a low price can be attractive, other factors can have a big impact on performance or safety.Ĭontact cleaners often contain alcohols and hydrocarbon solvents which are very flammable. There are several options available and trade-offs to consider when shopping for a contact cleaner. Contact areas with high resistance could become hot and conductive contamination could create a short. That means the current flow is potentially reduced or interrupted, affecting the performance of the device and potentially leading to safety hazards. Related types of products include electrical cleaners, switch cleaners, and (specific for automotive repair) battery terminal cleaner.Īny contamination in the contact area of an electrical device, like dust, dirt, grease or oxidation, can increase electrical resistance and possibly lead to connectivity issues. Contact cleaners are usually packaged in pressurized aerosol cans to provide a forceful spray that creates agitation and reaches into all the crevices of the connectors.
Soldering Iron Tips for Hexacon, American Beauty, and Other StationsĪ contact 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.Ī contact cleaner’s job is to quickly remove insulative contamination as quickly as possible, which can avoid a lot of wiping and scrubbing.
