Using your Brizo Invari Widespread Lavatory Lever Handle Set is easy. Just install it as you would any other handle set for a widespread lavatory. When using, simply grasp the lever handles and turn them to control the water flow and temperature. Remember, this product has a California Proposition 65 warning due to lead. So, after installing or removing it, make sure to wash your hands. To keep your handle set looking great, clean it regularly with a mild soap and a soft cloth. Avoid using abrasive cleaners as they can damage the brass finish. With proper care, your handle set will serve you well for a long time.
