It is essential to polish wooden furniture yearly. There are three main types of furniture polish - aerosol sprays, liquid polishes, and semisolid pastewaxes. Aerosol sprays are the most convenient but can harm furniture with silicone polymers and contaminants. Liquid polishes like emulsions and oils clean well but effects don't last. Semisolid pastewaxes are best as they minimally harm wood and are long-lasting, requiring infrequent buffing which preserves the furniture.
