PS: from amazon sales reference:
"The DeoxIT contact cleaner is a fast-acting deoxidizing solution.
This D5S6 contact cleaner spray was designed for use as a general
treatment for connectors, contacts, and other metal surfaces.
More than just any contact cleaner, DeoxIT chemically improves
electrical connections to ensure clean and clear sounds."
(..Not recommended for any keyboard components in Macs..)
