Oil stains on hardwood floors can be a nightmare to treat, especially when trying to maintain or sell a property. Whether it’s from a mishap with machinery oil, cooking oil, or any other greasy substance, homeowners need to clean up oil stains as fast as possible for the best results. This guide walks you through the steps to remove oil stains from hardwood floors and provides advice on protecting your floors in the future.
All About Oil Stains on Hardwood Floors
The porous nature of hardwood makes it susceptible to absorbing oils, which results in a dark oil stain. The severity of the mark depends on factors such as the type of oil, the finish on the floor, the type of hardwood flooring, and how quickly the spill is addressed. Common culprits of floor stains include motor oils and lubricants, essential oils, cooking oils, furniture polish, cosmetics, and liquid from office equipment, such as paper shredders.
Some hardwood floor finishes, including polyurethane, are more resistant to staining. Floors with a wax surface can absorb oils, but the damage won’t be as extensive as those with oil-based finishes, which are very vulnerable to staining.
Homeowners should take preventative measures to prevent oil stains on their hardwood floors. Place mats and rugs in high-risk areas, such as kitchen and entryways. Wipe up any spills, oil or otherwise, right away. Clean hardwood floors regularly and reapply floor finishes as needed, especially in rooms prone to spills, such as the kitchen.
Immediate Steps To Take After an Oil Spill
If you spill oil on your hardwood floors, quick action can prevent deep staining. Follow these steps right away:
- Blot the excess oil with paper towels or a clean cloth. Avoid rubbing the oil, which can spread it further.
- Sprinkle an absorbent material, such as cornstarch or baking soda, on the spill.
- Let the absorbent sit for 15 to 20 minutes to draw out the oil.
- Gently sweep or vacuum the powder.
If there’s still a stain after taking these measures, you’ll have to use one of the methods described below.
How To Remove Old Oil Stains From Wood Floors
Homeowners have several options when it comes to removing fresh or old oil stains from their wood floors. This list starts with solutions ideal for fresh or light stains and ends with suggestions for more stubborn marks. In some situations, you may have to attempt several of these tactics to completely clean the stain.
Dish Soap and Water
For fresh or light stains, mix a few drops of dish soap with warm water. Dampen a soft cloth with the mixture and gently blot the stained area. Rinse with a clean, damp cloth, then dry the area.
Vinegar and Water
This method is better for older or more stubborn stains. Mix equal parts water and vinegar, applying it to the stain with a soft cloth. Let the liquid sit for five to 10 minutes, before wiping it up with a clean, damp cloth. Allow the space to dry.
Commercial Hardwood Floor Cleaners
If other methods haven’t worked, there are commercial cleaners designed for removing oil stains. Choose a cleaner that is compatible with the floor’s finish, testing it on a small, hidden part of the floor to be sure it won’t stain. Follow the manufacturer’s instructions for the best results.
Mineral Spirits
While this remedy can be effective on tough oil stains, take extra care to avoid damaging the floor’s finish and wood. Apply a small amount of mineral spirits to a clean cloth and gently rub the stained area. Wipe away any excess with another dry cloth. Rinse the floor with water and allow it to dry.
Sand and Refinish
In extreme cases, homeowners may need to sand the stained area lightly with a fine-grit sandpaper. After clearing the sanded area, apply a matching wood stain and refinish the space to match the surrounding floor.
If the oil stain remains even after trying multiple removal methods, the floor’s finish is significantly damaged, or you’re concerned about causing further damage to the wood, it’s time to call a professional. Professional floor refinishers have access to specialized equipment and products that can often salvage even severely stained hardwood floors.
Final Thoughts About Oil Stains on Hardwood Floors
Dealing with oil stains on hardwood floors can be a challenging but manageable task for homeowners. Clean up any spills as soon as possible to help prevent the liquid from setting. If you’re faced with a particularly stubborn oil stain and you’re afraid of damaging the finish or wood, call a professional for advice.
