I got an used ThinkOutside Stowaway Bluetooth keyboard and would like to restore it, as it's a beautiful thing, especially the folding mechanism, but a lot of the keys are stuck and don't spring back up.
I think it's just because the rubber of the membrane is old. If I take the keys out, I see that the key's dome is stuck in the "down" position, and if I take tweezers, pull it back up, and press it back a couple times, it starts working again - for a while, until I close the keyboard anyway.
My question is then, is there any way to restore the membrane to its original springiness? Some oils I could rub on it, heat treatment maybe?
edit: My question is not about a mechanical keyboard, but about one with a rubber dome membrane, the ThinkOutside Stowaway.
