Compressed Air

[IAIHMB]

Just wondering, has anyone ever used Radio Shack's Velocity? I've had my computer for around 6 months, and I haven't cleaned it out. I just picked up a can of this, and when I use it I believe I am feeling moisture.

Test it out by blowing it through a thin cloth rag. Then hold it up to the light. You'll see a darker spot if there's much moisture.

I believe those canned compressed air jobbies have dry air or CO2. There shouldn't be much moisture in those at all. If there is, take it back.

We used to have freon-12 dusters called Effa Dusters. They were great because they had freon and no water. It was a pure, inert gas they sprayed. What was nice was when you wanted to find a heat intermittent you had to merely hold the can upside down and spray and out would come liquid freon. great as a freeze spray

But with the ozone layer being what it is, they are no more

It's not air, it's similar to Freon. (See the Material Safety Data Sheet at the RS site) It's safe to use as long as you have ventilation (Don't breathe the fumes.) Don't shake the can or tilt it and don't get it closer than 3-4 inches to what you are dusting.

The liquid is converted to gas when you spray it, not harmful to most any plastics. Let your device cool down before you use it, because it comes out at a low temperature and can damage hot devices.

Compressed air would be better, as long as the air were dry and clean. Most air compressors output oil and water, along with the air.

I use the stuff all the time, it's safe as long as you follow the instructions.

Ah, thanks for the help guys. I think I'll try actual compressed air first.

I use a vacuum cleaner. Simple.

In my opinionn ...



... on second thought, I defer to Capmaster as he IS AN EXPERT on compressed air and it's use.

One important thing to remember when using compressed air is to keep the can upright while you're using it. If you tilt it downward there may very well be some moisture coming out of it. Try angling whatever you need to clean so that you don't have to point the can at much of a downward angle.
