Whilst Matt Black resists scratches and chemicals, like all tapware finishes, it will still be susceptible to limescale build-up in areas where water supplies have a high mineral content. Limescale marks are created when standing water evaporates from surfaces and so can be prevented by drying your product after use. In situations where this is not possible however we advise that owners employ our 6 Month Maintenance Plan to control this build-up.
