What they did not tell you, was that the silicone oils and petroleum distillates in their product would actually cause harm to your finish over time. In the late 60s and early 70s refinishing shops made a lot of money refinishing hundreds of table tops when there finish softened and turned into a sticky, gooey mess. These products are much improved today and can be good for the occasional quickie just before guest arrive, but prolonged use can still leave a gooey mess and still no real protection. It is easy to tell if a customer has been using these kind of polishes. You can make swirl marks in the wet oil with your fingers, or lift a cloth place mat from the table top to reveal a dull spot the same shape of the mat (the oil was absorbed by the mat). Because the surface is wet, it will actually attract and hold more dust and pollutants from the air.
Let's take a moment and consider just what a finish is designed to do. First and foremost it is to seal the wood. Sealing the wood protects the wood from moisture changes, spills, stains, and surface abrasions. Second it is used to enhance the beauty of the wood grain. Have you ever heard someone tell how there produce "feeds" the wood. Unless your furniture is unfinished, or the finish has deteriorated, there is absolutely no way any polish, oil or wax is going to get through the finish to the wood. Another common misconception is that wood furniture is "alive" and need to "breathe," so don't seal the pores with wax. Wood furniture is not "alive" it can not "breathe" nor does it need to be "nourished" or "fed'' with oily polishes. Just the very opposite is the truth! Continual changes in humidity, not the lack of "feeding", cause unsealed wood to crack, warp, swell, shrink and glue joints to loosen.
