destinking the computers.

Qtips or ear swabs is what they are called. In that case with A4000 case it's simple smooth case with few crevices. Take apart Mac II, you will understand what I'm facing with this task. I once cleaned plastic grills for a household fan (that type that used round rotating vanes to direct air around via small motor.) Very tedious and hard, imagine that brushing hard with old toothbrush on small square of hole getting all grime and dust out. Mac II case is like that most of cavities are hidden. To few who have stinky cigarette-coated and others that is spoiled with grease films (as from kitchen enviroments) machines, mechanical cleaning and harsh chemicals and active chemicals is only way to break down those dried tough rancid oils (hardened like linseed oil on wood). Once I tried the major cleaning on a minitower peecee case (just that it, threw out working PSU. (!!) ) of cigarette smoke stain. Plastic sucks up stain+stink while painted surfaces does to small degree. Even well scrubbed and very C-A-R-E-FULLY few times with many cleaners and alcohol, lots of paper towels. I can't get smell totally out. Actually still emits stink strongly even surfaces is spotlessly clean and towels came up clean after last few days of off and on attempts. Gave up and traded it away for small "cash" towards other stuff. The multi-year of kitchen grease coating is TOUGH! Nothing we can find will touch it, boiling it in water and some soap got it softened enough to scrape'n scrub off with some work. That yuck was on kitchen plastic fan to get noise and viberation down in a college apt kitchen fan once, clean fan ran much better and quieter on oiled motor. :-) Mildew and fungus growth matter are stuck to the all surfaces and has to be removed by oxidizing action, scrubbing merely remove some of them.
