Bathroom fixtures are notorious for how fast they catch stains. But this is understandable because, in the end, they are dealing with waste materials most of the time. That is why you have to maintain them regularly if you want to keep them looking fresh. The exact way to clean them depends on the material. You can use strong chemicals on ceramic materials. But if it is metal, glass, or acrylic, you should use mild soap detergent and a non-abrasive brush for cleaning. Avoid using chemicals like chlorine for ceramic materials as it can damage the ceramic surface.
