Amiga 3000 driving me crazy

[carvedeye]

Every few months I have to complete tear down my 3000 and reseat everything to get it to work.  This time it was the flashing green screen of death, which after taking everything out and narrowing it down, appeared to be caused by the Warpengine 3040 even though it's screwed down to the posts.  In the past it's been the graphics card (I still get occasional graphics corruption on the graphics card and I have to take off the cover and play with it in the slot to stop it).

What is the best thing to use to give the connectors a good cleaning without risk of damage?  Spray electrical cleaner?

You could try cleaning the contacts?
