It's is ok to use a dust rag when cleaning the inside of a computer true or false

Hi!

You can use a piece of cloth to clean your computer, but there is a much more preferable method. 

Using compressed air is most often the best choice, and will minimise the risk of breaking any parts on accident.

While you technically can use a cloth or rag, it's not recommended. Depending on how you look at it, the answer to this question can either be true or false. 

I encourage you to take the information here, and decide for yourself! 

Hopefully, this helps! =)
