Using your Serna oval mirror is super easy. You can hang it horizontally or vertically according to your wall space and design preference. Just find a sturdy spot on the wall, use appropriate hanging hardware, and you're good to go. As for maintenance, simply wipe the mirror surface with a soft, dry cloth to keep it clean. Avoid using abrasive cleaners as they may scratch the mirror or damage the matte - black finish of the iron frame. Also, be aware that this product contains titanium dioxide, which is known to cause cancer in California.
