HG mould stain cleaners instantly destroy all mould, making the dirty black spots disappear. These unsightly black mould, moisture or weather spots are common in silicone joints between bathtub and tile wall, in the shower cubicle and in plasterwork. A regular spray variant is available: the HG mould stain cleaner, as well as a foam spray: the HG mould stain cleaner foam spray. Both extremely effective, but the unique foam formula has a less pungent smell, is even better at targeting the mould and, of course, gives less chance of splashing. In addition, the foam has the property of staying on longer and therefore provides better and longer penetration.
