How To Prevent Hardwood Floor Stains

While removing black stains from hardwood is not all that complex, it can be a time-consuming process. If you want to avoid it, ensure you’re carrying out regular cleans of your flooring.

Types Of Cleaning Products

Hydrogen Peroxide

Hydrogen peroxide is a powerful stain remover. It has excellent bleaching properties. You can use this quick and easy solution to tackle surface-level and massive stains alike. This ingredient is ideal for combating odours, like potty messes from pets or children. Plus, hydrogen peroxide is safe to use around kids and pets if you’re cautious.

Soak a cloth in hydrogen peroxide, then use it to dab the dark stains. Leave the hydrogen peroxide to dry overnight. For a prominent spot, use a towel and leave the soaked towel on the area for up to eight hours. After you remove the cloth and allow the spot to dry, the stains should disappear. Repeat the process as needed. Alternatively, you could spray or pour hydrogen peroxide on the affected area. Make sure to use a generous amount. However, you want to avoid applying it to areas of the wood where there’s no staining. Clean any spills or excess, or it may lighten wood that you didn’t want to bleach.


Chlorine is excellent at removing blood, tea, juice and food stains. It acts as a weak bleach or floor cleaner. It’s important to make sure you have a well-ventilated area before you get started. You’ll also want to wear gloves and eye protection.

White Vinegar

White vinegar is a great natural cleaning agent that’s great on stains. It’s also a powerful odour remover. The acidic nature of vinegar helps it break down grime so that you can remove it much more easily. To use it, add a cup of white vinegar to a bucket of warm water. Use a clean cloth to soak in the mixture, then rub the spot gently. Let the vinegar sit on the stain for a while. Then rub the spot one more time using a little more pressure. You should notice an instant and significant reduction in the stain.

Baking Soda

When you turn baking soda into a paste, it acts as an amazing cleaning agent. Baking soda is an excellent go-to when you’re dealing with stains caused by vomit, faeces, urine, or mould. Put on rubber cleaning gloves before you start making the paste. Mix the baking soda with vinegar or water to create a paste, then apply it to the stained area. Allow the paste to dry in the area. A few hours later, clean the spot with a soft, dry cloth. The baking soda removes the smell as well.

Oxalic Acid

Oxalic acid is great for black stains, rust or water spots. Using the acid is one of the strongest options to remove spots. You can purchase it from any hardware or home improvement store.

Mix with water to make a paste, then brush the mixture onto the stain. Leave it to soak into the area for a few hours and wipe it away. Repeat the process until the stain is gone. When working with oxalic acid, make sure to offer plenty of ventilation and wear protective gear.
