How to Remove Stains From Wood Furniture
Wood stains are of many types, from food and alcohol stains to pet and water stains. Removing these is possible through different measures, ranging from home remedies like baking soda and mayonnaise to commercial oil-based stain removers.
While social gatherings are great, they open up your precious wood furniture to a range of threats, from alcohol stains to your overexcited pet choosing to remind guests of his or her territory!
Don’t let those stains get you down, though—here’s everything you need to know about how to remove wood stains.
Removing Different Types of Wood Stains
Unfortunately, not all stains are made equal—some require more work to get off than others. Here’s how to tackle different types of stains on your wood furniture.
Stubborn stains usually arise from old, unattended water stains that have penetrated deeply into the wood. For such stains, wood bleach or oxalic acid can help. Dip a brush into whichever liquid you’re using and scrub the stained area. Let the bleach or acid sit until you notice the wood returning to its original color (this may take a few hours).
When this happens, wipe the bleach or acid away with a sponge or damp cloth and seal it with vinegar to stop any further discoloring.
For some extremely stubborn stains, you may need to turn to commercial heavy-duty, chemical-based stain removers. If you’re using these, use gloves and masks to prevent the chemical and its fumes from harming you.
Always follow the manufacturer’s recommendations for the amount and instructions for use.
As pet urine and feces contains a lot of bacteria, bacteria-killing solutions are necessary, such as hydrogen peroxide or vinegar.
For the former, soak a damp cloth with the solution and thoroughly scrub the affected area. If the stain doesn’t fade, leave a hydrogen-peroxide-soaked paper towel on the stained spots for a few minutes. However, this could further discolor the wood, so be careful.
If you’re using the latter, mix a cup of vinegar with a bucket of warm water and a few drops of grapefruit oil (for the odor). Scrub with this solution until the stains disappear.
Alcohol stains are identifiable by white discoloration. Luckily, this indicates damage to the sealer and not the wood itself. Rub the stain with a small rag dampened with a few drops of cooking oil. Add more oil if the stain doesn’t disappear.
Once the stain disappears, wipe the area clean with a dry cloth.
Blot any food left on the wood with paper towels. Use a soft towel dipped in a mixture of one part vinegar diluted in two parts water to remove the stain. You could also add a teaspoon of dishwashing liquid to the mix. Wipe clean with a dry cloth after the stain disappears, and let the table air dry sufficiently.
Such stains are best tackled with a mixture of warm water and a little bit of dishwashing liquid. Apply this mixture to the affected area with a rag, scrub lightly if necessary, and wipe clean with a damp cloth. You can let this air dry or wipe it once again with a dry cloth to dry it.
Strong, greasy stains need to be fought with a strong chemical. Ammonia is superb at breaking down fats and oils and hence, should be used for such stains. Mix cold water and ammonia and apply this to the affected area with a soft rag.
Water stains are the most common and problematic wood stains to deal with. You can tackle water stains in the following ways:
- Use a hairdryer on the maximum power and heat setting to dry the stain. Or if you have a heat gun, use that on a lower setting.
- Use oil-based solutions like mayonnaise and Vaseline. Just spread it across the stained area and let it sit for a few hours.
- Apply a small bit of non-gel toothpaste to the stained area with a clean cloth, wiping until the stain disappears. Wipe off any excess toothpaste with another clean, dry cloth.
Hot objects can leave behind a mark on wood in the form of white discoloration. Such stains, like alcohol stains, are indicative of damage to the sealant and not the wood—moisture gets trapped under the varnish because of the heat.
These stains can be removed by applying a mixture of equal parts baking soda and non-gel toothpaste to the area with a damp cloth and wiping it off once the stain is gone.
Homemade Wood Stain Removers for Grease & Water Stains
Often, you don’t need to look further than your kitchen or dressing table for the most effective stain-removal solutions! Here are a few of them.
A common skincare product, petroleum jelly can penetrate wood without causing any damage to it, just as it penetrates the skin. Petroleum jelly products like Vaseline can not only enrich the wood from the inside but also displace any water molecules inside.
Vinegar and Olive Oil
Olive oil is a superb conditioner that can deepen the color of the wood and nourish its fibers. Vinegar is an excellent cleaner; its acetic acid content is especially safe and effective for wood as it is used for the pretreatment of wood chips.
A mixture of one part vinegar and three parts olive oil, with a few drops of essential oil, can help get rid of minor, light stains.
Like petroleum jelly, mayonnaise displaces the water inside the wood and gets rid of any cloudiness on the wood’s surface. Just smear across the stained surface, let sit for a few hours, and wipe off with a paper towel. You can follow this up with polishing.
Hydrogen peroxide is a natural whitener and cleaner that can get rid of stubborn, dark wood stains. However, beware of any discoloration.
From cloth to closets, baking soda can get rid of stains on a range of surfaces. Form a paste with water and rub it onto the affected area. Let this dry, and then wipe it off with a clean cloth.
How to Remove Oil-Based Wood Stain From Wood?
Follow these steps to prep your surface for oil-based stain removers.
Step 1: Prepare Your Work Area
Use a drop cloth or tarp, and make sure all sharp, hard edges are padded or covered. If the stain is on the floor, tape the seams where the floor and the wall meet with painter’s tape.
Ensure that you’re in a well-ventilated area so that the fumes of chemical removers don’t affect you. Outdoors is great, but make sure there is no direct sunlight or strong winds. Also, ensure that you’re wearing gloves, goggles, long-sleeved clothes, and a mask to protect your skin, eyes, and lungs.
Step 2: Wipe and Clean the Wood
Clean the wood surface with soap and water if necessary, and ensure that it’s free of any dust or dirt. An easy solution to use is some dishwashing liquid in a bucket of lukewarm water with a soft cloth.
Step 3: Administer the Stain Remover
Follow the manufacturer’s instructions and apply the stain remover on the affected area as recommended. Use a paintbrush to apply the stain remover. Let this remover sit on the area for up to 20 minutes, and if necessary, reapply the stain remover.
Step 4: Break Out the Scraper
When your stain remover bubbles up or swells is when you know that it can be removed from the surface. Before it dries completely, scrape off the remover with a putty knife or plastic scrape. Be gentle.
If the remover is stubborn, a steel wool pad may be used. Make sure you scrub in the grain’s direction to prevent damage to the wood. Wipe clean with a damp cloth.
Step 5: Sand the Wood’s Surface
If you want to sand your wood surface, give it 24 hours after applying the remover to dry. Ensure that you’re well-protected, with a mask, goggles, and gloves, before you start sanding.
Start with medium grit sandpaper and exert just enough pressure for the stain to be removed. When you’re satisfied with the result, wipe off all dust and debris and sand with a fine grit to remove any sanding marks and smoothen the surface.
What Should I Look for in Wood Stain Remover?
Wood stain removers can come in different types, so knowing these types and how they work will help you pick out the ideal one for the task at hand:
- Caustic Strippers: Caustic strippers will dissolve the finish and are popularly used for wood stripping. These are strong bases or acids and are corrosive, more often than not. As the name suggests, these are caustic and quite harsh, which makes them great for stubborn stains.
- Solvents: Solvents like alcohol, toluene, and methylene chloride dissolve the existing wood finish and clean it efficiently. If you’ve got a painted surface that needs cleaning, these are the products for the job. However, they can be quite toxic.
- Biochemical Stain Removers: Though these are chemicals, they’re not as intense or harmful to humans, animals, and the environment as traditional stain removers. Chemicals like soy oil, terpenes, and citric acid are examples of biochemical stain removers.
