To clean old wood furniture effectively and safely, begin by identifying the type of finish to avoid causing damage. Perform a finish test using denatured alcohol on a small, inconspicuous area, such as the inside of a drawer or the back of the piece. If the finish dissolves, it is likely shellac, which is difficult to clean and may require professional refinishing. If the finish remains unchanged, it is probably lacquer, polyurethane, varnish, or oil, and can be cleaned at home.
For general cleaning, use a mixture of one ounce of oil soap (such as Murphy’s oil soap) with six ounces of water. Dip a soft, dry cotton cloth into the solution, wring out excess moisture, and gently clean the surface in small circular motions along the wood grain. Avoid working against the grain to prevent streaking or altering the wood’s appearance. After cleaning, immediately dry the surface with a clean, dry cloth to remove all moisture, ensuring no dampness remains.
For detailed areas like carvings or scrollwork, use a soft-bristled brush or an old toothbrush to gently remove grime, always following the direction of the wood grain. If mildew is present, use a mixture of equal parts distilled white vinegar and oil (such as linseed, olive, or vegetable oil) applied with a soft cloth, working along the grain. Wear protective gear such as gloves, goggles, and an air mask when dealing with mildew due to potential health risks.
After cleaning, consider applying a furniture wax to protect the wood and enhance its appearance. Use a clear wax for general maintenance or a darker tone (like medium brown or medium oak) for darker woods like walnut or mahogany to avoid a white residue in open grain. Apply the wax with a soft cloth, buffing in small circular motions along the grain to ensure even coverage and remove excess.
Avoid abrasive tools like steel wool or magic erasers, as they can remove the original finish. Similarly, avoid harsh chemicals like bleach or products containing ammonia, which can damage the wood or finish. For stubborn grime, a citrus solvent like Goo Gone may be used cautiously, but test it first on an inconspicuous area to ensure it does not strip the finish.

Hi! I just recently bought a few pieces of wooden furniture that I love from a consignment sale. But, before I can put them into use, I'd like to disinfect them – they're dirty, dusty and who knows where they've been. What can I use that won't destroy the finish/varnish/whatever on them? I'm a woodworking newbie but I know I shouldn't just put a lysol across it. Thanks!
I have a bunch of old wood furniture, mostly from the 30s-40s. I would like to clean it up, and bought howard clean and finish and feed and wax. I've already done the first round of cleaning, but it will need several, maybe even thousands ;). Questions are: how often can I do this routine? How will I know when it's as good as its going to get? How often should I do it for maintenance?
