How to Clean Hardwood Floors With Hydrogen Peroxide

The finish on hardwood flooring is neither fragile nor indestructible. Hardwood floors must be cleaned properly using the correct solvent level to protect their beauty and fine finish.

Even though you can’t damage hardwood floors by walking on them, all wood is susceptible to stains. And you can dull a beautiful hardwood floor by cleaning it with the wrong solvent. Used properly, hydrogen peroxide is not one of the damaging solvents. It is, in fact, a very effective stain remover and a reliable cleaner for hardwood flooring.

There are three ways to achieve a safe hydrogen peroxide solution for cleaning wood floors:

Three Options

  1. Use 12% hydrogen peroxide straight up out of the bottle.
  2. Mix 1 cup of 35% hydrogen peroxide (should you be able to find it), which is the “cleaning grade” strength, with two cups water, creating a 12% dilution of hydrogen peroxide.
  3. Mix 2 tablespoons of sodium percarbonate with a gallon of hot water as an alternative to achieve 12% hydrogen peroxide. When mixed with water, sodium percarbonate releases hydrogen peroxide.



Hardwood Floor Cleaning Procedure

Generally, you can clean wood flooring with a hydrogen peroxide solution and a mop or towel. Be sure to wring out the mop or towel so that it is lightly damp; too much water is bad for hardwood (bad for laminate wood-like flooring, too!). It’s best to use a nonabrasive cloth or a microfiber mop—not a natural fiber mop because it spreads too much water.

First, vacuum or sweep the floor well to remove all dust, hair, crumbs, and other debris.

Next, clean the floor in sections with your hydrogen peroxide solution of choice (one of the options above)—no need to rinse. Immediately dry with a separate rag before moving on to the next section.

For minor spot cleaning, pour 3% peroxide—the grade available at drug stores—into a spray bottle; then spray, wipe, and dry.

Removing Fresh Pet Stains

Pet urine can create unsightly dark areas on your floor that are accompanied by acrid odors. Cleaning to remove the stain and the odor as soon as it happens is optimum;  you can usually remove both with a combination of hydrogen peroxide and baking soda.

Spray paper towels with 3% peroxide, and lay the towels on the stains, ensuring the paper towel is very well saturated. Leave this for several hours, re-spraying occasionally with 3% hydrogen peroxide to keep the towels wet. When you remove the towels, sprinkle a liberal amount of baking soda on the stain and leave it there until it dries. Then vacuum away all of the baking soda.

Dealing with Problem Stains

One of the problems with pet stains is that even after treatment with hydrogen peroxide, the finish has been permanently damaged, and depending on the severity, maybe even the wood. If the finish has been damaged, your only option is to sand it off, then refinish the area.

You can treat permanently damaged/darkened wood by bleaching it with oxalic acid. Jut know that this may lighten the wood to a shade or tone that no longer matches the rest of the floor. In this case, you might be much better off calling in the pros.

  1. Always test any cleaning or restoration product and method in an inconspicuous spot, first. Always. Your wood surface with its stains is unique. Directives here are for typical or general situations, if there is such a thing.
  2. Hydrogen peroxide in  35% dilution can cause severe burns if not handled carefully. Read all packaging labels and inserts before handling. The 35% solution can bleach organic materials. Store in a safe manner out of reach of children.
  3. Always wear hands and eye protection.

    Do you have a way to get black stains out of wood? My husband overrated a plant and we didn’t see it until it was too late. Most likely mildew
