HG Mold Spray effectively removes all brown and brown stains caused by mold, fungi and algae. These unsightly black or brown marks are found on the silicone seal between the bathtub and the tile edges, in the shower enclosures and on the plaster. HG mold spray is also very suitable for removing coffee or tea stains from plastic workbenches. Spray with HG mold spray on the surface from a distance of 3 to 5 cm. Repeat the treatment on the most affected areas after 30 minutes. Leave the product on for 30 minutes and then rinse with water and a sponge.
