Using your Brizo Kintsu Widespread Lavatory Knob Handle Kit is super easy. Just turn the knobs to control the water flow and temperature in your bathroom sink. For the best experience, turn them gently to avoid any sudden water surges. When it comes to cleaning, use a soft, damp cloth to wipe the handles regularly. Avoid using harsh chemicals or abrasive cleaners as they can damage the finish and inlays. If you notice any water spots or dirt, simply clean them right away. Store any extra parts in a dry place to keep them in good condition. That's all you need to know to keep your handle kit looking great and working well for a long time.
