To remove permanent marker stains from wood, cover them with oil, wait five minutes, wipe the oil off, scrub the stains with toothpaste, rinse and buff the wood, and treat any remaining stains with commercial stain remover. This 45-minute process requires penetrating wood oil, rags, toothpaste, water, soap and commercial stain remover.
- Apply penetrating oil
Cover the stains with a generous layer of penetrating wood oil. Rub the oil into the wood, leave it on for five minutes, and then wipe it off with a rag. Pour on a fresh coat of oil, rub it in, wait five minutes, and blot away the excess.
- Rub the stains with toothpaste
Squirt white, non-abrasive toothpaste onto a clean rag, and rub it into the wood, following the direction of the grain. Add more toothpaste if necessary.
- Rinse the wood with soapy water
Leave the toothpaste on the stains for two minutes, and then rinse the wood with a rag dipped in soapy water. The rag should be wet, but not dripping. Do not leave any toothpaste residue behind. Dry the wood with a clean, dry rag.
- Apply commercial stain remover
If the stain remains, treat it with a commercial stain treatment approved for use on wood. Apply the stain remover according to the manufacturer's recommendations.
