Redacting PII from a PDF File using Adobe Acrobat

Hey guys, I apologize if this question has been asked a million times, however I’ve been googl’ing this and have not found any answers or anything helpful yet…

I’m attempting to redact PDF files using Adobe Acrobat and I’ve gotten close however I’m having trouble getting the robot select the area that I want redacted. I’ve tried using the record feature, but the output doesn’t seem to work when i try incorporating it into my workflow.

Can someone provide me with some assistance or links to videos that would also be helpful?
