The only thing I'd wash with water and soap is the front panel itself (completely removed from the instrument, and any pcbs or wiring harnesses removed from it), any knobs once removed from the pots, and possibly the rubberized keyboard membrane (if applicable) after removed from the backing pcb. They come out like brand new using hot-ish water, manual dishwashing soap (palmolive, dawn, etc), and if necessary an old toothbrush or larger scrub brush (with very soft bristles). For anything else, I'd just use compressed air to remove as much dust as possible and stop there.

Thank a lot for all your inputs guys! My instruments work very well for their age. I just wanted to make them great again:)
After reading your posts, I figured I will stay away from using any liquid or solvent for PCB cleaning. I would just? use electronics grade gas duster to blow dust off the surface of the boards. Or a small vacuum and a high quality horse hair brush would work better??

?I was under impression that excessive dust would pick up moisture that would damage my equipments. Is that true?
For some very old and dry sticker residue on the front panel, how should I safely remove them? I have Goo Gone but don't know if it's safe for instrument. It's kind of oily.
Thanks again!
Calvin?
