Unholy smoke

When you don't smoke, and seriously avoid second hand smoke, your tolerance for smoke smell gets very very low. What I have noticed in the past is that the entry point of the smoke catches a LOT of the stink, but the power supply is almost a filter trap. I bought a pizza box mac (size of a large pizza box and about 3 inches high, the 610 series box) that reeked. Stuck it in the garage and started working on it, stinky work too. I was afraid to really douse the motherboard, so I wiped it down with a cloth dampened in window cleaner, then used an air duster on it. The floppy drive and power supply though I took apart and flushed with contact cleaner. After letting it dry a few days, then run for a week, the smell isn't apparent unless the case is opened and you sniff the motherboard. I can live with that.
