How to Remove Machine Oil From Cedar Wood

Machine oil is any medium-density oil used for lubricating machine parts. When spilled on cedar siding, fencing, or roofing, it leaves a greasy stain. Washing it with a gentle cleaner may remove surface stains, but deeper stains will require a solvent. Many professional refinishers use power washing to clean cedar, although this method is not recommended, according to the Western Cedar Lumber Association, because it can cause extensive damage to the wood.

  Mix 2 tbsp. dish soap with 1 gallon warm water in a bucket. Dip a stiff brush in the sudsy water, and scrub the oil spot vigorously. Rinse with clean water, and allow it to dry. The oil spill may appear to be gone until the wood is dry. Repeat if necessary.

  Dampen a clean rag in turpentine, and wipe it over the oil stain. Scrub it with a stiff brush, and rinse. Turpentine is a highly volatile liquid derived from pine gum and wood. It is often used as a paint thinner or finisher, and it reacts with oils, breaking them down.

  Rinse the surface with clean water, and wipe it dry with a cloth. Allow it to air-dry, and then lightly sand the surface with sandpaper. If the grain is raised, sand it before applying any finishes to the wood.
