As in life, be considerate. Utilize no harsh chemicals for the brass bookshelf when cleaning. Brass will tarnish and acquire a patina if left untreated. You can use a metal polish to restore brass to its original color if necessary. Make sure you read all the care instructions when you buy a brass bookshelf from us and care accordingly.
