Dust the vanity frequently with a clean, soft, dry, lint-free cloth, and polish it on a regular basis with natural beeswax or a silicone-free cleaner.
Clean the surface regularly with fresh warm water and a non-abrasive clean cloth. A non-abrasive, neutral (pH-balanced) cleaner will help remove dirt and grime, but is recommended that you first try warm water only, then use a cleaner only if necessary.
When cleaning your new mirror, don't spray cleaner directly onto the mirror. Overspray can discolour wood framing your mirror. Instead spay the cleaner onto a cleaning cloth and then wipe the glass surface.
