If you notice whitish marks on your oiled floor after moving heavy furniture, don't worry, it's a common problem. The oil on the floor's wood isn't worn off, it's just been made very matte by the rubbing. To fix this, take a small, clean, and dry white cloth and put a few drops of finishing oil on it. Gently rub the rubbing marks with the cloth until the oil regains its shine, then gently wipe with a dry cloth to remove any excess oil. It's important to remove all excess and leave nothing on the wood surface. Avoid walking on the repairs for about twelve hours.
