The present disclosure relates to methods and compositions to control inorganic sulfide scale formations in oilfield applications, including flow lines, wellbores, and subterranean formations. An embodiment of the present disclosure is a method comprising: providing a treatment fluid comprising: a base fluid, a scale inhibitor, and a water clarifying agent; introducing the treatment fluid into a target region, wherein an inorganic cation and a sulfide anion are present in the target region; allowing the inorganic cation and the sulfide anion to form a sulfide precipitate; and using the treatment fluid to remove at least a portion of the sulfide precipitate from the target region.
