All of these questions will be discussed in this comprehensive article. Read it carefully, and you will be able to decide whether to bleach your precious hardwood floor or not.

What Is Bleach?

First of all, let’s learn a bit of bleach so that you can get a hint of how it works on hardwood floors.

Definition

Bleach is a widely-used cleaning agent. It is strong and can remove the most stubborn stains on floors, rugs, and clothes. Its active ingredient is sodium hypochlorite (1). Bleach comes in solid and liquid forms. But the liquid form is more frequently used.

Common Types Of Bleach

Do you know that there are different kinds of bleach? Let me show you what they are and their effect on hardwood floors.

Chlorine Bleach

This is the most commonly seen bleach in cleaning agents. It is a strong disinfectant and germ killer. It contains 5.25% of sodium hypochlorite. I have to warn you that this type of bleach is very likely to damage the hardwood floor. So try to avoid using it.

Oxalic Acid

Oxalic acid is the mildest kind of bleach. It is made of plan-based compounds. Therefore, it is the only bleach that is safe to use on the entire hardwood floor. It works best in removing rust stains.

Two-Part Bleach

This variety of bleach is called “two-part” because it has 2 components, namely hydrogen peroxide and sodium hydroxide. Two-part bleach is best known for the ability to alter wood’s color. You should be careful when using it.

Non-Chlorine Bleach

This type of bleach is very different from its other counterparts. It contains sodium percarbonate rather than sodium hypochlorite. So it is not as toxic as the others and quite environmentally-friendly. You may hear some people call it oxygen bleach.

Pour Bleach
Different types of bleach are suitable for specific stains.

Can You Bleach Hardwood Floors? The Ultimate Answer

I will go straight into the answer. Bleach is not an ideal cleaner for hardwood floors. Although hardwood floors are said to be very durable, it is sensitive to harsh cleaners, especially bleach. This strong cleaning agent can cause serious damage to your hardwood floor.

As such, if you have more options to choose from, don’t ever think of bleach. However, this applies when you intend to bleach the whole hardwood floor. In practice, you can bleach a small area of the floor, which has a stubborn stain on it.

Some factors decide whether a hardwood floor can be bleached or not. The first one is the type of finish. Surface finishes can endure bleach, while penetrating finish is much more sensitive to it.

The second one is the age of the hardwood floor. Newly installed hardwood floors can have less damage when interacting with bleach than old hardwood floors.

In addition, the type of bleach can also affect how it reacts on hardwood floors. Some types are milder and less toxic than others.

How Bleach Affects Your Hardwood Floors?

In this section, I will explain the potential risk you have to face when using bleach on your hardwood floor.

It Can Weaken The Wood’s Structure

When bleach seeps deeply into the hardwood floor, it destroys the connections between lignans, the compounds that makeup wood. As a consequence, the structural integrity of the hardwood floor becomes weaker over time, leading to creaking and splinters.

Bleach can also damage the floor finish.

It Can Discolor The Wood

The great amount of sodium hypochlorite in bleach can change the color of your hardwood floor. To be more specific, it lightens the color of the wood, just like what it does for clothes. You should be careful when using bleach on any area of the hardwood floor.

How To Bleach Finished Hardwood Floor

In case your hardwood floor has a layer of finish, you have to strip it before bleaching the floor and refinish it after you’ve finished. But make sure you pay attention to how the floor reacts as well as tightly stick to this instruction.

With this method, you can bleach a small area or the entire hardwood floor.

Bleach Hardwood Floors
This guide is the only thing you should know when bleaching hardwood floors.

What You Need

  • Bleach (oxalic acid)
  • Sander or sandpaper (80-grit and 12-grit)
  • Chemical stripping agent (optional)
  • Lacquer (optional)
  • Baking soda
  • Paint remover (optional)
  • Varnish remover (optional)
  • Dust mop
  • Hot water
  • Stiff brush (or scrub brush)
  • White vinegar (optional)
  • Floor finish

Step 1: Clean The Floor

Whatever you want to do on the hardwood floor, clean it first. Use a dust mop to clean all of the dust and dirt.

Step 2: Remove The Current Finish

The next task is to strip the existing finish using a sander or a chemical stripping agent. It is best to use a sander rather than a chemical stripper because it is simple to use and not toxic like the stripper.

Another way is to use paint remover, varnish remover, or lacquer thinners, depending on what is available to use. Place some rags or paper towels all over the floor. Create a thick layer. Next, pour your chosen product on it until all of the rags or papers are damp.

When the old finish is softened, get a wood scraper or plastic spatula to remove it. Make sure you do not gouge the hardwood floor.

After you strip the floor, use sandpaper to make the hardwood floor smoother. Use 80-grit sandpaper first, then switch to 120-grit sandpaper.

Step 3: Test The Bleach On Hardwood Floor

Choose an unnoticeable area to test the effect of bleach on your hardwood floor, if no damage appears, you can proceed to the next step.

Step 4: Bleach The Hardwood Floor

If you wish to apply bleach on the entire hardwood floor. I recommend that you use oxalic acid because it is the most gentle one and can be safe for the hardwood floor.

Add 12 ounces of oxalic acid powder to 1 gallon of hot water. Apply the bleach solution all over the floor using a scrub brush, soft-bristle brush, or stiff brush and gently scrub the floor. Make sure the solution is always warm. Reheat it when necessary. Let the bleach sit for 10 minutes.

Note:

  • Prepare yourself with eye protection when working with oxalic acid because it can be harmful to your eye.
  • Wear gloves when making the oxalic acid solution. Use your hand or a wood stick to stir it.
  • Do not use natural bristles. Avoid metal tools as well.

Step 5: Rinse The Hardwood Floor

Rinse the floor completely with clean distilled water. Using distilled water is very important because it helps to avoid iron stains.

Step 6: Neutralize The Hardwood Floor

There are two ways that you can decrease the effect of bleach on your hardwood floor. Since you’re using oxalic, mix 2 tablespoons of baking soda and 1 quart of hot water. White vinegar is also an option.

Step 7: Sand The Floor Again

After you neutralize the floor, let it dry for at least 1 day. Then sand it one more time with 120-grit sandpaper. This will help the floor to be smoother. You can apply a thin layer of lacquer on the floor before sanding.

Step 8: Refinish The Hardwood Floor

The final step is to reapply the floor finish to protect it from future damage. Choose a suitable sealer for your hardwood floor and apply it following the manufacturer’s directions.

Lastly, you should repeat the bleaching process as many times as necessary until the hardwood floor looks perfect.
