I can vouch for that - someone sent me a 386 motherboard he'd "cleaned" with
Amberlube (IIRC). Now the board attracts dust like there's no tomorrow. It
*needs* rinsing in IPA followed by deionised water, but I haven't got any.

Ick... IIRC Electrolube produce a foam cleaner that (they claim) can rip
grease and grime off a PCB without causing any damage to components.
Fluxclene is also quite good, but it stinks to high heaven. Alcohol based,
IIRC, with a slight citrus scent... For $DEITY's sake, use it in a
well-ventilated area - outside if possible. I used a can of it for 20secs in
a large kitchen and ended up with a headache that lasted 40 minutes... Oops.
Never did that again...
