I recently bought a Kensington Desktop Vacuum to use on my desktop computing equipment. The instructions that came with it only talk about proper maintenance of the vacuum and not much about how I can safely use it with my computer equipment or WHICH equipment. I also bought a can of Memorex Air Duster and again, no instructions on what equipment I can safely clean with it or how. I look inside my computer and see that the insides really have a buildup of dust, but I don't want to do anything harmful. Any direction on using either of these two products would be greatly appreciated or any tips of caution. I've had computers for years, but have never attempted to clean one, more than just dusting with a soft cloth on the outside. Thank you in advance for any info that may be provided.
