Remove the front panel circuit board. Insure any dress items like the front
pannel overlay are not on it and put it in the dish washer with the usual
cleaner (any dishes too). This will do a very good job and is not caustic.
It dry it well, if it come out with water in the switches don't panic.
Put it in an oven set real low (you want 140 degrees) and bake it
dry. Lubricate the switches with a contact leaner that has some low
residue lubricant in it. Drying is a no rush thing. FYI soap with
plenty of clean water rinse is the least damaging thing you can use.
I've done this many, many times (whole production runs!) using this
approach.
Any switches once dries that are failed/flaky can be replaced easily as
they are common parts.
