Compressed air, often referred to as compressed gas, is one of the most effective tools for removing dust and debris from hard-to-reach places in office equipment. In this article, you’ll find practical advice on safely and effectively using compressed air in the office to keep devices clean and ensure their longevity.


Uses of Compressed Air

Compressed air is particularly useful for:

  • Cleaning keyboards
  • Removing dust from the inside of computers
  • Cleaning printers and scanners
  • Removing debris from other office equipment


How to safely use Compressed Air

Preparation for cleaning

  • Turn Off the Device: Always turn off and unplug the device before starting the cleaning process. This prevents damage to the equipment and ensures safety.
  • Proper Location: Perform the cleaning in a well-ventilated area. Dust particles can become airborne, so it is best to do the cleaning outside or in a room with good ventilation.


Technique for using Compressed Air

  • Hold the Can Upright: Keep the can upright while using compressed air. Holding the can horizontally or upside down can cause liquid gas to leak.
  • Limit Shaking: Avoid shaking the can too vigorously while using it. The product contains propane and butane, and excessive shaking can cause the gas to liquefy and expel liquid.
  • Short Bursts: Use short bursts of air to control the airflow. Long bursts can cause the can and surfaces to cool excessively and result in moisture buildup.
  • Maintain Distance: Keep an appropriate distance from the object being cleaned (usually about 10-15 cm). Being too close can damage delicate components.


Cleaning the keyboard

  • Invert the keyboard: Gently turn the keyboard upside down and shake it to remove loose debris.
  • Short blasts: Use short bursts of compressed air to blow away dust and crumbs between the keys. Aim the nozzle at different angles to reach all corners.

Maintaining the interior of the computer

  • Open the case: Open the computer case following the manufacturer’s instructions. Ensure the computer is completely unplugged.
  • Clean fans and heatsinks: Direct compressed air at the fans, heatsinks, and other components that accumulate a lot of dust. Short, precise bursts are crucial to avoid damaging delicate parts.
  • Avoid direct contact: Avoid direct contact of the nozzle with components. Maintain a proper distance to prevent damage.


Cleaning printers and scanners

  • Turn Off and unplug the device: Before cleaning, turn off and unplug the printer or scanner.
  • Remove paper: Take out the paper from the tray to gain better access to the device’s interior.
  • Clean the interior: Use compressed air to remove dust and debris from inside the printer or scanner, especially around paper rollers and other moving parts.


Cleaning other office equipment

  • Precise cleaning: Compressed air is ideal for cleaning other office equipment such as phones, copiers, and fax machines. Direct the airflow to hard-to-reach areas to remove dust and debris.


Additional Tips for Using Compressed Air

  • Avoid inhaling dust: Try not to inhale the airborne dust while using compressed air. It may contain harmful particles that can irritate the respiratory system.
  • Store the can properly: After use, store the can in a cool, dry place, away from heat sources and open flames.
  • Avoid unnecessary use: Do not use compressed air for cleaning surfaces that can be cleaned with other methods. Compressed air is mainly intended for hard-to-reach places and delicate electronic components.



Compressed air is an extremely useful tool in any office for keeping electronic equipment clean and functional. With proper technique and safety precautions, dust and debris can be effectively removed from hard-to-reach places. Regular cleaning of office equipment with compressed air not only improves its appearance but also extends its lifespan, resulting in better work efficiency and lower repair and maintenance costs. Remember to follow safety guidelines to enjoy a clean and safe workspace.
