preferred to any chemicals if you're dealing with dirt
yes, I agree too.
I do this all the time - with all sorts of vintage circuit boards -- computer, arcade, pinball, etc..
A few steps I would include >before< washing is this,
- Remove the corrosion from the pcb traces and tin the copper traces again.
---- use either a hobby xacto knife to clean the individual traces(#10 blade works great)
---- or a dremel for the severe corrosion on ground planes and such.
- Repair any copper traces as needed - you should check continuity on every trace thats been affected.
---- some traces can suffer a break from the corrosion
---- usually a drop of solder can fix this or add a piece of stripped bellcore wire.
- Repair any corroded Vias
---- these can fail to make connection between the top and bottom of the pcb.
---- you might have to clean out the Via hole first since it might be clogged with corrosion too.
- Brush on the vinegar and rinse off with [at least 91%] isopropyl alcohol, then wash.
---- I just use a clean toothbrush for this to get in small areas - and a stiff paint brush for tight areas.
---- I use either a heat lamp or just sit it out in the sun to quickly evaporate any water drops
---- sometimes I use an air compressor to speed up the process.
