The Difference Between Types of Furniture Polish

Share:

Furniture-care products do five things more or less well:

  • add shine to dull surfaces
  • add scratch resistance
  • aid in dusting (by picking up the dust rather than spreading it around)
  • aid in cleaning and
  • adding a pleasant scent to a room.

So what about the claim of replacing natural oils? Claims from manufacturers were (and still are) all over the map. Even worse were all the contradictory opinions of my professional-refinishing colleagues, museum conservators, furniture-store clerks and my customers.

Furniture polishes couldn’t possibly replace the natural oils in wood because only a few exotics, such as teak and rosewood, had natural oils (actually oily resins) to begin with. Almost all furniture woods contain water, not oil.

I also figured out that furniture polishes couldn’t possibly “feed” a finish. With the exception of shellac, finishes are plastics (and shellac resembles plastic). To feed one of these plastics the furniture polish would have to penetrate it, which would mean soften it. This doesn’t happen, and it isn’t something you would want to happen.

Clear Furniture Polishes

Clear polishes are petroleum distillates, essentially mineral spirits (paint thinner) that evaporates a little slower. These are good for cleaning grease or wax and for picking up dust. They are usually packaged in clear plastic containers. Their primary benefit is for dusting.

Emulsion Furniture Polishes

Emulsion polishes are a combination of petroleum-distillate solvent and water. They are milky-white in color. They clean water-soluble dirt in addition to grease and wax and are usually packaged in aerosols. Emulsion polishes are good for dusting and better for cleaning than clear polishes. (But cleaning is not often needed on furniture.)

Silicone Furniture Polishes

Silicone polishes are clear or emulsion polishes with some silicone oil added. This oil is very slick and remains on the surface for a week or longer. This is how you identify these furniture polishes – by the smear you can cause with your finger days after application. Furniture polishes without silicone evaporate within hours. Silicone polishes add shine and reduce scratching in addition to dusting and maybe cleaning. These polishes are the most popular with consumers, by far, because they keep furniture looking rich and deep until the next dusting. Silicone polishes are also controversial.

Paste Waxes

These are more difficult to apply and can’t be used for dusting or cleaning but remain on the surface for months (unless removed by one of the furniture polishes). Use paste wax for a fairly permanent shine and scratch resistance, but keep in mind that you’ll then need to use a damp cloth, chamois, or some sort of duster for dusting rather than furniture polish.
