"Clean out safe" is a mission objective in the story mission "Nova? No Problem!" in Borderlands: The Pre-Sequel
Walkthrough[edit]
Head over to the safe in the back of the room now. It is open so you can get whatever is inside. You will always find the ECHO Recording: Springs' Safe Password.
Just collect that and Janey Springs will call you back to reward you.
