Need help learning how to clean a computer and what to use

[refmon]

I've haven't done this before so I'm a little scared. Can somebody link me the best video tutorial for cleaning the dust off of a computer? I would like to use a computer vacuum but it costs over $100 on amazon, if anybody knows of any good computer vacuums please tell me. I've also heard that some air cans have moisture that can damage the computer, how can I tell if its bad for my computer?

I'm going to use this but is it safe for my computer?

Thank you and sorry for my mistakes, English is not my first language.

That is safe to use, AS long as you keep it upright. If you turn it over it will not be a very good idea. So as long as its upright you are good to go. Those vacuums are not the best investment either, air is fine. Also you English is fine 😀

Thank you but can you show the best video tutorial?

I dont know of any videos, its fairly straight forward though, keep the nozzle a few inches away with the base of the canister flat, and pull the trigger.
