USE AND CARE OF DECORATIVE DOOR HARDWARE FINISHES:
Non-Brilliance: Cleaning solvents should not be used. Frequent
cleaning \is far more important. To clean, use clear water and
a soft cloth. After cleaning, a coat of hard wax will add protection.
Brilliance : In most cases, water and a soft cloth should
clean the lock. If required, use a mild household soap. In severe
climates, a residue may appear. This can easily be removed with
standard glass cleaner or chrome polish and a soft cloth.
