How do I use canned air on my computer?

It's amazing how quickly dust bunnies and debris can accumulate inside your computer case. Over time, all that buildup can clog airflow, cause overheating, and even damage sensitive components. Luckily, canned air offers an easy solution for blasting away dust and keeping your computer clean. Before grabbing the can, always turn off and unplug your computer first. The compressed air spray can then be used to safely dislodge and remove dirt from fans, vents, and other tight spaces. When used properly, canned air is a gentle but thorough way to banish dust. 

Let's jump into our main topic of how to use canned air cans to effectively clean your desktop or laptop PC.

Shake Can

Before using the canned air duster, give it a good shake first. This agitates the compressed air inside and makes the spray more effective for blasting away dust. Shaking the can for 5-10 seconds mixes up the propellant and contents to maximize cleaning power. Be sure to hold the can upright when shaking to avoid any liquid escaping. Choosing a high quality electric air duster like the Metro ED500 DataVac can provide strong spray pressure when shaken. The right canned air gives you the cleaning strength you need.

Hold upright

Always keep the canned air duster upright when spraying it inside your computer. Tilting or turning the can may cause liquid propellant to shoot out, which can damage sensitive components. Hold the can nice and vertical for a steady, even spray pattern. Using a handheld electric air duster with a nozzle gives you better control for aiming the airflow precisely. With either canned or electric air, proper upright technique is key.

Aim nozzle away

Carefully aim the nozzle several inches away from the components you're cleaning inside the computer case. Avoid holding the air spray right up next to fans, boards, or chips. This focused spray could damage delicate parts. Keep a bit of distance and gently blow dust away. Aim the nozzle strategically to dislodge, not blast. Cleaning tools like the compressed air duster from the brand XPOWER offer nozzle attachments for more controlled airflow.

Spray short bursts

Always use quick, short bursts of canned air instead of long sprays. Press the nozzle for just 1-2 seconds at a time. This controlled spraying prevents overcooling any components from prolonged airflow. Periodically stop to inspect, then hit stubborn dust with another brief round of spray. An electric air duster has advantages for precision cleaning control. But whether using canned or electric dusters, short controlled bursts are key.

Target dust buildup

When blowing dust, target areas with heavy visible buildup first. Get into crevices caked with dirt and debris around vents or between components. The highest pressure electric air dusters like the DataVac ED500 excel at blasting dust away. Or use short bursts of compressed air cans to dislodge stubborn buildup. Keep spraying until the thick layers clear out. Then move to lighter dust areas, using a sweeping side-to-side motion to gently clear off surfaces. Always aim the air nozzle carefully to target the dirt precisely.

Dry components off

After spraying away dust, give a few targeted blasts around any components that got wet from the canned air. This helps accelerate drying so no moisture is left behind. Quickly blow fans, boards, and chips until completely dry to the touch. Cordless handheld air dusters make this easy, with no worries about propellant liquids. But even using compressed air cans, take a few extra seconds to dry. This prevents any risk of water damaging sensitive inner parts.

Clean fans gently

Use extra care when blowing dust off fans inside the computer. Keep the canned air nozzle at least several inches away and aligned straight on, not angled. Short gentle bursts remove dust without spinning the fan blades too fast. Slowly work around all the fan edges. An electric air duster like the XPOWER A-2 has attachments to make fan cleaning safe and easy. Avoid tilting compressed air cans when cleaning fans, as liquids can spray out. With either tool, a light touch keeps fans dust-free.

Wipe down case

Finish by wiping down the outside of the computer case to remove any remaining dust. Use a microfiber cloth lightly dampened with water or a gentle cleaner. Avoid excessive liquids that could seep inside. Carefully wipe vent holes, crevices, and perforated areas that dust collects in. For stuck-on dirt, rub small circles to lift debris. This removes any visible dust the air sprayers missed. Keep the outside surfaces clean along with the internals for a spiffy, dust-free computer.


Canned air is an effective tool for cleaning dust buildup inside your computer. Always unplug the computer and shake the can well before use. Hold it upright and aim the nozzle a few inches away to safely blow dust out of internal components. Use short bursts instead of long sprays to avoid overcooling parts. Target visible dust first, then finish by drying any damp areas and gently wiping the case exterior. Used properly and regularly, compressed air spray keeps your computer clean and dust-free for optimal performance.
