The maintenance of this kind of furniture will depend on the type of wood, texture and finish used to build the same; you cannot look after an antique piece in the same way as you would treat a Baby Grand Piano or an MDF cabinet; remember that wood tends to age and the exposure to sun and external factors tends to produce a darkening effect on certain areas; however you can easily remove stains from wood furniture. This is probably one of the reasons why MDF is becoming a very popular material to build bookcases, TV stands and tables.
The best way to protect your wood furniture is by polishing it every week; however, avoid using low quality products; it doesn’t mean cheap products as there are plenty of inexpensive products on places such as Amazon or your local supermarket that are of very high quality. When searching for a cleaning product make sure it doesn’t contain alcohol and ammoniac - this chemicals damage the surface of the wood; and read the reviews carefully, both positive and negative.
Remove Fingerprint and Smudges
At least once a year or every other year, you should put your expensive furniture in the hands of a professional in order to restore the look and polish. If your furniture has an enamel cover or paint, you could easily clean it with a slightly dampened cloth and soapy water (rinse and dry); however, if you own rustic furniture, you must moisture it often in order to retain the look (you can use linseed oil as a moisturizer but you must apply it carefully and avoid overuse). Wax from candles can be removed easily if you place a small piece of ice on it once the wax hardens and dries. The ice will make it soften and easier to remove.
