How to physically clean your computer

We give our computer a good work out, the amount of time we are spending on them has increased dramatically compared to 10 years ago. You could be using your computer to store photo collections, shopping, social media, games, forums, work, emails…. there are so many reasons to use your computer each and every day.  Computers may need a clean internally to help improve the hard drives performance (that’s a whole other post), but they also need a regular physical clean too.

Imagine the dirt that can build up between the keyboard keys and the grime found on the mouse.  I find I have to clean mine often due to fingerprints on the screen and dirty keyboard buttons.

Steps to physically clean your computer

  1. Turn off computer
  2. Unplug the computer from the powerpoint
  3. Using a hairdryer on a low or cool setting, blow out all the dust and dirt from between the keyboard keys.
  4. Wipe over the keyboard with a slightly damp cloth to remove dirt build up
  5. Wipe the mouse with a slightly damp cloth.  If you have an older mouse remove the ball from the mouse, clean away dust from the rollers using a cotton bud, place ball back.
  6. Wipe over computer tower
  7. Wipe over all electrical cords
  8. Wipe over the back of the computer screen
  9. To clean the screen use a damp lint-free cloth with water only and then wipe the screen.


  • Never spray the computer with water or chemicals, wipe using a slightly damp sponge
  • Instead of a hairdryer, you could use a vacuum with brush attachment to get dirt particles from the keyboard
  • Be careful not to adjust any knobs or controls
  • If unplugging electrical cords take note which cords go where
  • Use only a soft, lint-free cloth. Avoid abrasive cloths, towels, paper towels, and similar items that might cause damage.
  • Keep liquids away from the computer.
  • Don’t get moisture into any openings.
  • Don’t use aerosol sprays, solvents, or abrasives.

Hey Kat, love all your posts.
Just wanted to offer you my support on your healthy life. I try not to consider it a weightless journey as this tends to imply a beginning and end. Keep up the great work. Will check you out on the FB page. You have inspired me so much. I think about your advice daily. You WILL reach your goal weight, piece of cake (low cal of course). Thank you for sharing your journey with us.
I am typing this on my new iPad, bursting with excitement and the organizing possibilities. Just wondering if you can offer any apps to do with organizing please? I am very new to this technology so am sorry if the questions is a daft one.

Computer, keyboard and mouse are all looking great. Just replaced the batteries in the keyboard since they were running low.

This is so great! I love cleaning my computer, I just went through and cleaned out my computer then cleaned it physically. Thank you for the great post!

Hi Katrina, using a hairdryer or vacuum cleaner on a computer is a no no as it can potentially cause static buildup which can damage electronics. To clean a computer you should be using compressed air and the container should specifically mentions that it doesn’t cause static buildup. I bought my compressed air from Bunnings.
