Clean Your Keyboard With A Hair Dryer

Clean Your Keyboard With A Hair Dryer

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 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.

How to Clean Your Keyboard []


  • I know a lady at my work that used a hair dryer on her mac laptop and she melted her keys, very expensive to replace. I don’t recommend any type of heated air gun to clean keyboards.

    Specialised air cans for electronics are good for cleaning out dust in computers, a good tap on the table is always a good method for those standard qwerty keyboards.

    Simply moving your keyboard away from you when you eat/smoke at the computer, clean your keyboard daily with a cloth from laptops and a tap on the desk for the normal external keyboards.

    I was also introduced to this nifty little cleaner from 3M:
    Another lady at work is extremely messy, you looked at the keyboard and would cringe at the site of it, with bits of food and sticky keys … eeek!.
    With a bit of time, taping and cleaning with this tool the keyboard came up all nice again.

    • That’s why you use the cold setting? All hairdryers have a cold blast button, or room temperature heat setting. By blowing cold air onto recently heated and styled hair, it is supposed to cause the protiens in the hair to set. Whilst this is probably based in pseudoscience. It doesn’t make hairspray melt and poses less of an ignition risk, so salon hairdryers all have the option.

      Back to the topic. I have been using a hairdrier on my laptops for years. It works great.

  • I have heard stories similar to Wazz’s about melted the circuit board inside the keyboard with a hair dryer. I restored a wireless Logitech that suffered a soaking in rum and coke following these steps.

    – remove batteries
    – remove all keys
    – wipe inside with slightly damp cloth
    – rinse all keys with water (to remove stickiness)
    – leave dry for a day (or more to be safe)
    – put parts back together

    I think I also unscrewed the keyboard, not just removed the keys.

    I really didn’t expect it to work but it was flawless
