Advice wanted for cleaning edge connectors, IC sockets, etc.

<"tuner wash" would be bad for the connectors, PC board, plastic IC <sockets, silk screening, solder mask, etc. I considered rubbing <alcohol, but I don't know what the effect of that would be either. I <checked the FAQs that I know of, and about all I came up with was <someone's technique of "giving the circuit board a good scrubbing" <with dish soap and swinging it on the end of a string to dry it. As <this technique strikes me as possibly dangerous, to myself, the 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. Allison
