How to Clean Wooden Doors at Home: Right Method, Common Mistakes

An interior wooden door is touched every day by hands and dust, and sometimes by food or grease marks. Most damage to door finishes comes from wrong cleaning: a soaking wet cloth, strong detergents or scouring pads. Here is how to keep a door clean without harming its finish.

First, find out what finish your door has

The cleaning method depends on the surface finish, and a simple test will tell you what it is. Put a few drops of water on a hidden corner of the door:

• If the drops sit on the surface and are not absorbed, the finish is lacquer or polyurethane and resists surface moisture.
• If the drops are slowly absorbed and the wood darkens slightly, the finish is oil or wax, so you should use as little liquid as possible.
• If the door is covered with matt paint, it is sensitive to abrasive cleaners and should only be cleaned with a soft cloth.

Everyday method: soft cloth and little moisture

For routine cleaning, a slightly damp (not wet) microfibre cloth is enough. Always wipe along the grain. Straight afterwards, take up the leftover moisture with a dry cloth. Water that stays on edges, joints and the bottom of the door can slowly cause swelling or open up the joints.

Wipe a wooden door damp, not wet, and always finish dry.

How to deal with stubborn stains

For grease or fingerprints on a lacquered door, dilute a little mild dish soap in lukewarm water, dip a cloth in it, wring it out well and wipe the stain. Then rinse with a plain damp cloth and finish by drying. Do not press hard on old stains; repeat gently several times so that the finish is not damaged.

What never to use on a wooden door

• Strong cleaners such as limescale removers, bleach and ammonia-based products; they dull the finish or leave marks.
• Scouring pads and abrasive powders; they leave permanent scratches.
• Direct steam cleaners; heat and moisture both damage the wood and the glue.
• Cheap waxy sprays; they leave a greasy film that attracts dust and makes later repair of the finish harder.

Periodic care: how often

For doors with an oil or wax finish, apply a thin coat of wood oil or wax every six to twelve months and buff it with a soft cloth. For lacquered doors, gentle cleaning is usually enough. If the lacquer has cracked or gone dull, it is better to renew the finish with a specialist's advice rather than patch it. Our guide to wood finishes explains the difference between the types.

Do not forget the top, bottom and surroundings

Dust on the top edge of the door and marks near the bottom are often overlooked. Once a week, clean these spots with a soft-brush vacuum or a dry cloth. If the door sticks or rubs after cleaning, the cause is probably warping, not the cleaning; see our guide to fixing a warped wooden door.

In short: identify the finish first, work with a soft cloth and little moisture along the grain, and always dry at the end. These few small habits keep a door looking fresh for years.
