When you don't have compressed air handy, Inc magazine suggests that a standard hair dryer can remove built-up dirt on and under your keys.
The hair dryer is just one of 10 methods Inc.com suggests, with varying degrees of effectiveness and cost. We're a little wary of the CyberClean and USB vacuum suggestions, being both relatively expensive for what they are and a bit single-purpose. Luckily, the hair dryer, heat on or off, fills in for that little USB gadget, if at a much higher, temporary power cost. Other suggestions, like busting out the isopropyl alcohol or entirely removing your keys for a thorough cleaning, are pretty much spot on.
What's the cleverest way you get at the grime under your keys? Tell us in the comments.
