Using your Brizo Kintsu Widespread Lavatory Knob with Mother of Pearl Inlay Handle Kit is super easy. Just turn the knobs to control the water flow and temperature. When installing, follow the included instructions carefully. Make sure all parts are tightened properly to avoid leaks. For cleaning, use a mild soap and a soft cloth. Avoid using abrasive cleaners or tools as they can scratch the Mother of Pearl inlay or the other parts of the fixture. If there are any stubborn stains, you can soak a cloth in a solution of water and vinegar and gently wipe the affected area. Regularly check the handles and connections for any signs of wear or looseness. If you notice anything wrong, contact Brizo's customer service for assistance.
