As you know, using WD-40 on wood works effectively. However, it’s vital to be careful during the application process to ensure that no harm occurs.

First, spray some WD-40 on the stain on the wood, let it soak, and then use a damp sponge to remove as much dirt as possible. 

Then take a towel and dry the damp spot. You can also apply some carpet cleaner to the area to remove any residue, as WD-40 has a strong odor.

The composition of WD-40 includes 60% to 80% petroleum ether (saturated hydrocarbons), 2% flavor, and 1% to 5% carbon dioxide (greenhouse gas), depending on the product type. Therefore, it may leave a WD-40 residue on the wood. But don’t worry, the solution is straightforward!

Remember when using WD-40 on wood, as the product repels water, first wipe it off with a cloth or paper towel as much as possible. You can then wash the rest with a soapy liquid-like plain dish soap or shampoo. 

Use without diluting with water first. Let the soap do the work of dissolving the residue; perhaps you can use an old toothbrush to work on it. Once you’ve done that, rinse it off, and you’ll see no more WD-40 residue left. You can also try one of the liquid hand soaps.

However, you will need to reapply the product after it dries constantly. Spraying some of it into the gap in the affected part of the floor can stop the friction and the squeaky noise that comes with it.

  1. Thoroughly clean the affected area. 
  2. Keep the mouth of the WD-40 can as close to the floor as possible, aiming for the gap between the two wood boards. Spray slowly into the cavity.

  4. Ventilate the area to dry. 
  5. Keep candles and other open flames away from the area.

We’re talking about creaking wood and minimal work on the joints. You can also wipe off any excess with a cloth lightly moistened with mineral spirits to avoid the risk of slipping. Unless you let your finished wood floors sit on top of it, you’re unlikely to leave any stains (but it’s always best to test in a concealed area first).


As the name suggests, WD-40 is primarily suitable for water displacement. However, it can also be used as a cleaning and corrosion protection for electrical appliances or metal. Sometimes it can also loosen rusty connections.
