I recently acquired a Shangri-La that I need to do this to. I was planning on just firing it up and cleaning all the switches and steppers that are gummed up to verify everything actually works, then I’m gonna break it down and get OCD with every single piece and part. I’ll be following this thread for others’ suggestions.

There’s a pretty sweet video on youtube somewhere of someone doing this to a bingo back box.

I think I would drench the bottom board in mean green let it do it’s thing for about 10 mins then rinse it.

I was going to do the brake cleaner method on my mech board. I started on the corner where all the wires connect to the female jones plugs and the cleaner basically started washing away the colors on the old style wires, almost like it was bleaching them.

Is there a preferred brake cleaner to use?

This was a while ago but im pretty sure i just used Advance Auto parts brand of cleaner

'67 Williams Shangri La, I need to finish my restoration and the last piece is the mech board in the cabinet and Id like to shop the mechs in the backbox. It needs cleaned pretty bad so Im not above drenching it in degreasers and water but if there is a cleaner available like brake cleaners or contact cleaners I'd rather use that kind of product
