I'm about to start up recording again for a concert series that has been inactive since before covid, my cables and setup gear (not mics or recorders) have been in storage in a closet since 3/20. Although the area has not been subject to any extreme elements or humidity, I worry about oxidation of the XLR contacts. Is there any recommended cleaner I could quickly use once I get access to the equipment about an hour or two before showtime?
