Compressed air can is quite expensive. Even worse, you have to buy the item multiple times if you want to clean your PC from dirt and dust.

But, is there any alternative ways to clean PC without having to use a regular compressed air?

Turns out, there are many methods you could use. Here are some approaches to clean a computer (and other electronic devices) with simple tools you probably already have or with a cheaper alternative.

#1 Take out the heatsink and clean it with brush

Heatsinks in your PC is the part that responsible the most regarding temperature problem. Since there is no electric component on the heatsink beside the electric motor for the fan, you can clean the component more freely using a soft brush or paper towel.

It’s also possible to clean the fan using the same tool. But, make sure you did not press the blades too hard so it won’t be deformed or broken.

Some people also suggest adding a little water to the brush or paper towel for removing dirt that very hard to clean. Then dry the components for about two or three hours to ensure there’s no water left on its surface.

#2 Manual hand blower can be a cheap alternative

Manual hand blower is probably one tool you need to have by your side and your computer. It works similarly like a compressed air canister, but cheaper and relies on the grip strength of your hand.

It blows air blast after you squished the silicone container part. The pressure is enough to clean the dust on the surface of electronic components without having you touching it.

The price of this tool is about $4 to $7 depending on your location. It’s a small investment since you don’t have to buy the same item regularly for the sake of cleaning your electronic devices.

#3 You can use your vacuum cleaner as a blower

There are some vacuum cleaner products that have two abilities in one device. It can suck dust and dirt, while the other side can be used as a wind blower.

Of course, the air blast may not as strong as pressurized air can, but it’s good enough to ensure the PC’s heatsinks and fans have spacier room to distribute cool/hot air.

Please note that not all vacuum cleaners have this feature. Check on the device’s manual book to see what it is capable of.

#4 Or borrow your sister’s hairdryer

Hairdryers work in the same way as a blower — it blows air. But, there’s a catch. The air from a hairdryer is usually hotter and can melt several plastic components if exposed for a long period of time.

Hence, please only proceed with this option with caution. If you feel the wind blast is warmer than it was, you can stop the usage and wait until the electric motor inside it cooled down before continuing.


Alright. That’s some ways to clean your PC without a compressed air can. I personally love a manual hand blower since it can target a small area and can be used multiple times without electricity.

How about you? Which method do you prefer to clean your PC?
