Steam mops use steam to clean floor surfaces. The mop head uses a pad to clean rather than the typical bundle of yarn used with traditional mops. When a steam mop is left in one position too long or hard water is used in the water tank, white spots will be left on your floor. There is no reason to worry because there is a simple way to remove the white spots.
Moisten one end of a towel with undiluted white vinegar.
Wipe away the white spot with the towel.
Moisten the opposite end of the towel with water and wipe the vinegar from the floor. The vinegar smell will go away once it is dry.
Use distilled water in your steam mop tank to prevent future white spots on your floor.
