(I forgot  where I got this, somewhere online while googling for a vacumn that blows air too).

 

If you smoke your cleaning job might be much larger than you want to tackle. I use to work at a computer store and one of our clients a CPA was a chain smoker. We did annual cleaning on their equipment and his PC would take me over a half day trying to scrub out all the tar build up that covered every component in the system. I would go home my fingers stained looking like I was a smoker with major headaches after cleaning his sytem. I had to use alchol to dissolve all the tar inside his system between the alchol fumes and the disolved nicotine I would get through my fingers I always dreaded having to clean a major smokers system.

 

Also as a side note if used with the proper caution not to touch things a vacume can be a great first step before going to the canned air. It sure cuts down on the amount of dust you will be sending out.

 

If you smoke

 

If you smoke, then cleaning your computer is the least of your problems. If anybody had any doubts as to the effects of second hand smoke, this gives an idea of what effect airborne particles have on something that takes in air.

 

One user suggested turning off the computer while dusting, so that airborne particles are less of a problem. The same logic applies to smokers, only more so. One option is to turn off the computer while smoking, but a better option is to go outside to smoke. Finally, quitting smoking can prolong the life of your computer, other office equipment, furniture, paint, and just about everything in the office. I won't go into health benefits since it's really beyond the scope of this topic, but it's an added bonus if your primary motivation is helping your computer.
