How to identify a short circuit on logic board

Can anyone help me identify where short circuits on a logic board are? I am speaking in general terms to help fix water damage when cleaning alone does not help. I have seen some people use Oscilloscopes. Some that use multimeters... I have no experience with either and am just trying to learn.

thank you for your help!
