How do you safely clean dust from your PC? You should see mine, the keyboard is so dusty. Can I blow dry it?
My desktop has the most dust. I believe it's because I never close my window. How often do you dust your PC?

Wiping it down carefully with a dry cloth should be OK. Just be careful that you don't push dust into internal parts.

Once a year , I send it for deep cleaning by the computer guy and also to reapply thermal paste. For the external portion, I wipe it with microfiber cloth.

I do regular dusting and sometimes use a wet wipe.
However, I do not usually get the laptop opened by Service center person unless there is a special need.
