I'm sure you've all heard us talk about canned air before in some of our tips. We use it here quite often and I'm willing to bet that a lot of you use it too. But, for those who don't know, what is canned air? Well, it's basically air that is sold in a pressurized can that is used to clean out dust, dirt and any other grime that may exist in hard to reach places. It's mostly used on sensitive electronic devices, including the insides of computers and between keyboard keys.
Canned air comes with a long nozzle that shoots out a blast of air, which blows out all of the debris found in tight areas. A good rule of thumb is to use canned air whenever you have a spot to clean that a vacuum or a piece of cloth cannot reach. Now, the air used for canned air is not the same as the air we all breathe. The mixture is often made up of nitrogen and other harmless gases. It is also known to be ozone safe, which is always good.
Now, even though canned air is safe to use on your computer, etc., you do need to pay attention to the kind you buy. A wonderful WorldStart reader informed me that there are two types of canned air: flammable and non-flammable. The can will clearly say whether it's flammable or not, so make sure you read the label closely. If a certain propellant in the canned air mixes with a high voltage from your computer, it could cause flames. So, even if you think air is non-flammable, don't be so sure. Read the label and just be as careful as possible when working with canned air. It's better to be safe than sorry. At least that's what I always say!
