Just a few comments on the cleaners that have been
mentioned for the removal of cigarette smoke residue.
(probably tars and nicotine).
Benzene is on of the best cleaners I have ever used. It
is also one of the most active and deadly carcinogens available. It is absorbed through the skin and by breathing
the vapors. Do not use it without proper protection.
Carbon tetrachloride is also a carcinogen and is also absorbed through the skin and by breathing the vapors.
If you subject it to heat, such as cleaning a just soldered
joint, you will get the sweet smell of "new mown hay". That is phosgene, a WW II poison gas.
I think that in the USA ethyl alcohol is denatured by adding a poisonous aldehyde to it that has a boiling point a few tenths of a degree different from that of ethyl alcohol. This is so that you cannot distill out the ethyl alcohol from the untaxed denatured ethyl alcohol without also getting the aldehyde.

I forgot to mention what I use to clean electronics (like pots, switches and other electromechanical devices). I've never tried it for cigarette related residue, but it may work since they dissolve oils and other "gunk". Good thing about it is you can spray it all over the mobo, cards, etc., without hurting anything. These are usually either carbon tetrachloride based or benzene based. These are those almost "instantly evaporative" type cleaners. You probably can't get just go out and get them anymore in stores since I think they are considered a "hazardous" material now. I get mine from electronics supply places. Just be sure you get one that states "safe on plastics" because not all of them are. Radio Shack used to sell it, don't know if they still do. They may be based on another type of chemical now.
Another note on the citrus cleaners....they probably don't have even be a "cleaner". For a long time (until it ran out) I was using a plastic pressurized bottle of "Citrus deodorizer and odor remover". Not even sold as a cleaner. It would even clean recent paint, and dried paint on your hands, remove tar, and grease.

I'm not familiar with any of the "Citrus based" cleaners other than something called "Goo Gone". It will remove just about anything. If it's hard or really thick, it needs to sit for a while before you wipe it off, and sometimes you have to brush it a bit. Most of the other citrus based cleaners I've SEEN don't appear to be as thick as Goo Gone, so this Goo Gone might be concentrated a bit more. It will also remove permanent marker type inks, glue from tape residue, many other stubborn things. I've also had good luck with bleach-based spray cleaners. Doesn't have to be Clorox brand, any brand will do.
Sometimes for indelible inks, any type of pressurized **canned aerosol** spray will work. I say ANY kind, since it's not what's in it that cleans, it's the propellant. I don't know if those type of "cleaning propellants" are still used here, but they still may be used in Canada. I used to use Lysol (or generic) aerosol spray to remove inks. Hair spray will also work, but that's not a wise thing to use for obvious reasons. :-) It's also not good for plastics. -Clint

I have a number of clients who are long time smokers and the insides of their pc's are marked with cigarette residue combined with dust particulate. Added to the heat inside the computers and brick is produced.
It's on the heat sink, video cards, and on the mobo itself. I've never been able to remove it safely.
Has anyone ever removed this stuff? Safely?
