Caring for your Gainsborough product

Door hardware is easy to clean. Give your levers and knobs, including roses and plates, a gentle wipe every two months with a soft, damp cloth. A solution of soap and water could also be used to remove dirt from knobs, roses, but make sure the liquid doesn’t go into cylinders. Avoid using acidic or abrasive substances which may contain solvents, i.e. cleaning products, as they may cause a deterioration of the finish.
