YOU SHOULD NEVER USE BLEACH ON MOLD IT DOES NOT & WILL NOT KILL/GET RID OF THE MOLD, IT ONLY COVERS IT TURNING IT WHITE MAKING IT APPEAR AS THOUGH IT HAS DISAPPEARED BUT IT REALLY HASN’T!! WHEN TRYING TO REMOVE MOLD YOU SHOULD ALWAYS USE NOTHING BUT PURE PEROXIDE!! MOLD PROFESSIONALS WILL TELL YOU THE SAME EXACT THING!!
