Contact-cleaner, also known as switch-cleaner, is a term for a chemical, or a mixture 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.
An open contact of approximately 1.5 mm shown between two posterior teeth. The shred of meat, at right, was recovered from the open contact more than 8 hours after the patient had last eaten meat, even though the patient claimed to have brushed his teeth twice since eating the meat the night before, thus exhibiting the importance of maintaining cleanliness of open contacts with an oral hygiene ...

This “redox” reaction (reduction and oxidation) produces small bubbles that help to clean the contacts. After 6-8 hours, the hydrogen peroxide becomes an eye-safe saline solution. [4] At this point, it is safe to use the contact lenses. After extended use, the platinum coated disk must be replaced.

Cold welding was first recognized as a general materials phenomenon in the 1940s. It was then discovered that two clean, flat surfaces of similar metal would strongly adhere if brought into contact while in a vacuum (see Van der Waals force). Micro [1] and nano-scale cold welding [2] has shown potential in nanofabrication processes.
