Glad it survived. If you have some Caig DeoxIT D5, give it a couple of sprays. I use it to clean, lubricate and deoxidize audio and electronic components, and to care for remotes and fobs.

Dumb question........ do you open up the remote and spray inside (and remove battery first)?
Been using it for 20+ years to clean the pins on audio tubes, the sockets on tube amps. Handy stuff to have around for sure, if you're into electronics, especially for home and car audio components.got to get some of that
