If you spilled oil on your wood floor, you've come to the right place. We're here to explain how to use household products to sop up the mess before it soaks into the wood. We can help even if the oil was absorbed and the stain has set in. Read on to learn three different ways to get oil out of a wood floor using baking soda, dish soap, mineral spirits, TSP, or Fuller’s earth.

This article is based on an interview with our cleaning specialist, Jon Gholian, founder of Cleany. Check out the full interview here.

Things You Should Know

  • Spread kitty litter or baking soda over the spill ASAP and vacuum it up after at least 30 minutes.
  • Froth dish detergent and water in a bowl to make soap suds, then rub just the suds into the stain with a soft cloth.
  • Wipe off the suds and excess oil with a soft, damp cloth, then dry it completely.

Cleaning a Fresh Spill

  1. The faster you deal with a spill, the better your chances of getting out the stain. [1] Use a newspaper or soft, absorbent cloth to dab up all the excess oil. Don’t rub, or you could work the oil further into the wood.
  2. Next, cover the stain in an inch (2.54 cm) of absorbent powder, like baking soda, kitty litter, or talcum powder. Let it sit for at least 30 minutes or up to overnight, then vacuum it all up.
    • Wear gloves to prevent skin irritation.

  3. Pour dish detergent into the bottom of a bowl, then fill it with water. Use regular dishwashing detergent or a similar cleaner designed to cut through oil. [2] Mix up the water with your hands to create soap suds.
  4. Scoop the suds, and not the water, out of the bowl and pour them on the stain. Use a soft cloth or brush to gently work the suds into the wood grain to break down the grease. [4]
  5. Dip a cloth in cold water, then wring it out. Water can stain wood, so get out as much as you can. Clean up the suds and oil entirely. [5]
  6. Once the suds are removed, dry the wood gently and thoroughly. Allow the area where the spill was to air dry completely. If possible, open a window or use a fan to speed up the drying process. [6]

Cleaning Older Spills with TSP or Mineral Spirits

  1. Scratch a hidden part of your floor with a sharp knife to determine the finish. If clear material flakes up, that’s a wax finish. If no wax beads up, it’s surface finished. If you have a surface-finished floor, use odorless mineral spirits . If it’s wax finished, get trisodium phosphate (TSP). [8]
    • Surface-finished floors have a urethane coating that keeps water from sinking into them. They require a different kind of care than wax-treated floors, because the urethane just sits on top while the wax actually penetrates the wood.
    • If you’re using TSP, mix 1 tablespoon (.17 g) into 32 fluid ounces (950 mL) of water to make a cleaning solution. Use a glass bowl and a wooden stirrer to keep the TSP from reacting with metal.
  2. Open a window or use an electric fan to provide airflow through the room, since the fumes from these cleaners are harmful. Put on rubber gloves and a respirator if you’re using mineral spirits, and put on goggles as well if you’re using TSP. [9]
  3. Pour some mineral spirits onto an absorbent cloth, then place it on the stain. After a few minutes, wipe the mineral spirits away and wash the wood with water before completely drying it off. [10]
    • If you’re using TSP, dip a sponge in the mixture and rub down the area with the stain. Dip another sponge in warm water, squeeze it out, and rinse all of the TSP solution off of the floor. [11]
    • If the stain persists, repeat this step.
  4. If possible, use a fan or open a window to aid the drying process. [12] Wait until the area is completely dry before proceeding to the next step.
  5. Squirt a small amount of wax polish onto the affected area and rub it into the wood in a circular motion using a soft cloth. [13] If you have a surface-finished floor, apply a coat of polyurethane and let it dry.

Cleaning Stubborn Stains with Fuller’s Earth

  1. If you have an especially tough stain on a wax-finished floor, use Fuller’s earth to remove it. Wet a rag with a little acetone , then wipe down the area with it. [14]
    • Fuller’s earth is an absorbent powder that mechanics use to clean grease stains off their garage floors. It’s made from the same stuff as kitty litter, but since it’s such a fine powder, it can more easily come in contact with the entire stain.
  2. Mix a little bit of acetone into Fuller’s earth until it makes a thick paste. Spread the paste on the stain, then let it dry until it turns back into a powder. [15]
    • Make the consistency of the Fuller’s earth between wet sand and clay.
  3. Use a clean cloth or a stiff bristled brush to break up the Fuller’s earth, then sweep it up. If it feels stuck, use a palette knife to ease the dried paste off of the floor. Keep repeating this process until the stain is completely gone. [16]
    • Take care not to scratch the floor if you’re using a pallet knife.
  4. Mop the floor using a pH-neutral cleaner for wood floors. This will get rid of any Fuller’s earth residue. Change your mop head as it gets dirty to ensure you’re still picking up residue and not just spreading it around. [17]
  5. If you can still see oil in the wood grain, carefully sand down the area with fine-grit sandpaper. [19] When you’re done, rub a little bit of wax on the area in a circular motion, until the wood soaks it all up.

    Expert Answer
    If something oily spills onto your wooden floor or furniture, spring into action straight away. Gently rub the area with a soft cloth and dish detergent to break down the grease. Then, rinse with cold water. If one application doesn't work, repeat the procedure—be sure to keep children and pets out of the room until you're done. Let the spot dry, then smooth the raised grain with fine sandpaper.

      • If your wood flooring is new, using a DIY solution may void the warranty. In these cases, it may be best to seek professional help with older or stubborn stains. [20]
