WD-40 is out; thanks. Contact cleaner only. Any suggestions on the best?

CRC QD (Quick Drying) contact cleaner is what I use.

The Toggle Switches on the front panel of your DMC20 are totally sealed, no amount of whatever liquid you spray on them will ever get onto the contact surfaces. Toggle Switch as an example, there are literally 1000's of these in many different configurations.

The only thing you can do is to replace the switch, which appears to be somewhat easy if your tech savvy, if not take it to someone whom is. The switches appear to be mounted on a PCB rear-mounted to the faceplate using the switches as standoffs / mounting hardware.
