No, nothing will remove everything. But it removes the great majority of what's there. |

That's ridiculous, considering the amount of risk we're talking about here, which is about as close to zero as you can get. There's risk with canned air, as well. Do you avoid that, too?

The loose dust bunnies are easily removed, but they aren't the problem. I routinely see systems where the CPU heat sink fins are packed tightly with a combo of dust, cat hair, and who knows what else. That stuff laughs at me when I reach for canned air. When it comes out, it's in small chunks, almost cement-like. -- Char Jackson |

My solution for packed hair ect is a small air nozzle on my air compressor.
done properly it does no damage and gets rid of the build up. -- AL'S COMPUTERS "Char Jackson" wrote in message ...

I was thinking of attaching connections to an air ball to use a nozzle. I'd have to cut off that tire inflating end first obviously. |

I don't think it's all that complicated so I wouldn't hold my breath looking for an "Expert". You could make your own and become an expert yourself I love inventing little gadgets and such. You could mount small plastic tubes at several points throughout your system and connect a vacuum pump. http://www.youtube.com/watch?v=5nT9oc1Oi5I The number things that can be most effective are preventative.

I don't quite remember just how many years it was for me but I can say I never smoked in my adult life and I will be 65 in July. |

No, but I've had a quick look: the prices are even more eye-watering than I remembered: http://uk.rs-online.com/web/p/work-area/7199879/ That has some .pdf files which might say something useful (I haven't looked). -- J.

Finally, we had a stack of paper about a foot high documenting our efforts, and a GSA exec wandered by on a tour, asking about problems. Shortly after we showed the tour group the stack of paper, a dozen of the correct vacuum cleaners showed up, current contract or not. We didn't even get a bill!. So yes, small shoulder carry vacuum cleaners suitable for computer use are made. The price those days was almost twice that of a similar model without the anti static and noise suppression options. About $100 instead of $59.95 |

I have an old "Green Machine" that is also a rug cleaner. It has been working fine for what seems to be over 10 years. It has no bag and has a large container that looks like it would hold more then any bag. From what I remember the bag cleaners don't suck as much as the bag gets full. It is a bit of a pain to empty but I do it out on my back deck every few months or so. I've been waiting for it to die so I can look into a newer model that might work better. You might be right about the old style being more convenient. |
