I've never used compressed air before and am a little scared to, especially after reading http://en.m.wikipedia.org/wiki/Gas_duster which says it can cause serious injury or death if inhaled. I am also scared of getting any of the liquid on my components. Is there some alternative I can use, such as blowing air through a straw, I don't care if it takes longer. Or are these things I'm reading about compressed air over dramatized and false?
