How to Remove White Spots From Hardwood Floors

Julie Christensen

Modern wood floors are coated with polyurethane, making them all but impervious to stains and damage. With age, though, these finishes wear thin. Exposure to water, sun and wear all take their toll. Water spills left on a wood floor may evaporate, leaving white or grayish spots. Alcohol, medicines or perfumes may also cause white spots or streaks. If stains don't disappear with treatment, call a professional wood floor finisher, advises Michigan State University Extension.

Properly cared for wood floors may last 30 to 40 years or longer.
  1. Wipe a dime-size amount of paste wax on the stain.

  2. Rub the stain gently with the steel wool taking care not to destroy the finish.

  3. Wipe the surface clean.

  4. Apply a small amount of camphorated oil to a clean, lint-free cloth to wet it. Wipe the oil on the stain and immediately wipe dry with another cloth.

  5. Add two to three drops of ammonia to 1 cup of hot water. Dip cheesecloth into the ammonia solution.

  6. Rub the cheesecloth on the stain. Wipe with a damp cloth.
