How often you use polish on wood furniture very much depends on the type of furniture you have and the type of polish you use. Be sure to use a polish that is designed to be used with wood as some polishes contain chemicals that can actually damage fine wood, attract dust and dull surfaces. Typically you’ll find that polishing your furniture 1-2 times per week is more than enough. Though it’s perfectly fine to adapt this according to how much you feel is needed to contain the dust.
