Fixing flaky buttons

I have a bunch of aging instruments I need to tune up. One commonproblem with these things is the buttons become flaky over time.(I'm not sure what the name for this kind of button is, but whatI'm talking about is a "stateless" push button, which functionslike a computer keyboard key. It is typically used to incrementa number or move a cursor or something. You push it and it movesthe cursor one space. You push it again to get another space.Often, if you hold it down, a repeat kicks in after a delay ofa half second or so.)Over time, the contacts inside the button become dirty or oxidizedor whatever and the button becomes flaky. You have to push hardto get a response, or you get multiple responses from one push,etc.If I can get the button open, I can usually improve it by cleaningit with alcohol, but sometimes even that doesn't completely fixthe problem.Does anyone here have tips for this kind of thing?I'd especially like to know if there are tricks for fixing thesewithout opening the buttons up. There are a lot of differentkinds of buttons and some are hard to open and some take mea while to figure out how to open.
