What do you use to clean the fans of a laptop?

I know how to clean the fans, but what I do with it. Blow in will hardly work

Compressed air

Dust in a PC is usually cleaned with air pressure.

Here is the air pressure spray I use: https://www.amazon.de/...007PS6DEW/

How to clean a fan:

.

You can clean it with a vacuum cleaner or air pressure.

I would never use it to clean a fan!

Yes, that's how we do it at work and that's how I do it privately.

Pure botch, because the fan can't be cleaned with it, at best you spread a little dust with it.

No. That's not true. It's blown out…

Well, keep dreaming…

With a vacuum cleaner or compressed air. Make sure that the fan wheel does not turn. Hold the fan with two fingers or needle-nose pliers. Reason: The rotating fan can turn the motor into a dynamo and current can flow into the electronics. This in turn can lead to a blackout of the PC.
