Why don't you just replace the switches for something that will last forever? If you're not experienced enough to do that you can either learn how to, or pay someone else to do it. 

I recommend something like Kailh GM 4.0.

I've actually seen a few videos on that, was thinking about it but I never soldered anything. Not a complete stranger with tinkering but never done it before.
