Using these Brizo Beauclere wall - mount lavatory wheel handles is easy. Just turn them clockwise or counter - clockwise to control the water flow. When using, be gentle to avoid excessive force that might damage the handles. As for maintenance, clean the handles regularly with a soft, damp cloth. Avoid using abrasive cleaners as they can scratch the malachite inlay. If there are any stubborn stains, use a mild soap solution and wipe it off gently. Store the handles in a dry place when not in use to prevent rusting or damage to the malachite.
