A bathroom smart mirror is exposed to moisture every day. If water spots are left to build up, they are usually harder to clean later.
Caring for a smart mirror is simple. After everyday use, gently wipe the mirror surface with a soft microfiber cloth to keep water spots from lingering and building up.
Make a habit of wiping it as you go. There is no need to wait until limescale is obvious, and the mirror will stay clean and clear more easily.
A quick wipe every day keeps care effortless!
