Every day, sanitary ware is exposed to scale because water and scale go hand in hand. Scale leaves a dull haze on tiles, shower cubicles, plastic bath tubs, sinks, taps, worktops and in the toilet. Fortunately we have HG "scale away foam spray", but sometimes the scale is more persistent than we thought! So we developed HG "scale away foam spray 3x stronger" especially for those situations! This extremely powerful, 3x stronger formula removes that type of persistent scale quickly, easily and thoroughly, leaving a brilliant shine.
