It's oil. Whether you realize it or not, it covers everything in it's path. > Okay, another option for those of you who are thoroughly disgusted by > my suggestions, let me substitute something else for the feather > duster: a microfibre towel.

Do you know why the dust clings? :) Wiseass. See above, where you said "magnetism" doesn't attract dust. A magnetic field (not necessarily, magnetic mind you) does; that item you mentioned uses static electricity to bring the dust to it and make it stick. I wouldn't suggest you wipe down ram sticks with it. No, actually; I suggest you should. It would fit right in with your repairs. -- "Hrrngh!

The vast majority of household dust (excluding homes next to freeways, etc) is made up of human skin cells. The next major component is vermin pieces -- insect parts and feces, then pet dander. Living in the SF Bay Area we're inundated with medical researech for UC Berkeley, Stanford, and UCSF Medical school. From time to time various projects have asked for household dust in order to make various antigens. Antigens, for the most part, come from human parts such as skin cells. From time to time we might hear an ad on the radio advertising for household dust for a study. It's because of the plethora of skin cells present.

Most components are reckoned to be what common sense would suggest. Plain old dirt; bits of fabric fibres; animal hairs etc with human skin cells being a very minor fraction. Guess we'll never know for sure and each will continue to believe as they wish! Must say that what I see in my computers doesn't look much like skin cells. Henry

I can't argue about what most dust consists of, but I can say that some dust is magnetic in nature. > Living in the SF Bay Area we're inundated with medical researech for > UC > Berkeley, Stanford, and UCSF Medical school.
