Using your Oskar Brushed Nickel Shower Mixer is easy. Just turn the knobs to adjust the water temperature and flow to your liking. When you're done, make sure to turn off the water completely. To keep it in great shape, wipe it down with a soft cloth after each use. Avoid using harsh chemicals or abrasive cleaners as they can damage the finish. If there's any build - up of limescale, you can use a mild vinegar solution to clean it gently.
