Dive in to learn how to get rid of burned spots on a wood surface. 

How to Remove Burn Marks From Wood Fast

Here, we look at the basic requirements to get this job done. Of course, the tools may vary based on project or preference, so don’t worry if you have one or more items not included in this list. 

Materials to Help you Remove Burn Marks from Woodwork

  • A random orbital sander (for a wooden floor)
  • Protective face mask 
  • 150-grit, 180-grit sandpaper 
  • Tack cloth 
  • 220-grit sanding block 
  • Water-based polyurethane 
  • Clean rag or towel 
  • Paintbrush 
  • Steel wool 
  • Baking soda
  • Toothpaste 

How to Remove Burn Marks from Wood

If you are working on minor to moderate burn marks, you will simply need to sand out the burned area or scrub it with steel wool and then reapply the wood’s finishing to restore its original look.

Step 1: Clean the Entire Surface 

Cleaning is essential as it helps give you a better sense of the extent of the damage. Do not use any household cleaning products or water in this step. Simply dip a clean rag or towel in some warm water and wipe the surface with it. 

The other reason you want to clean the surface before starting to restore it is to remove any loose dirt, dust, and grime that might get in the way when repairing the burns.

Let the wood dry completely before moving to the next step. 

Step 2: Remove Superficial Burns with Toothpaste and Baking Soda 

After cleaning, you will see if it is a mere singe on the finish that has not reached the wood. 

To clear such a superficial burn mark, create a sticky paste by mixing a non-gel toothpaste and baking soda in a bowl. Then apply it over the mark in the direction of the grain. 

If you’re unsure if baking soda is essential, check our on “Can baking soda remove wood paint?”

Let the paste sit there for at least five minutes to fully set in, then wipe it away with a clean rag. 

Alternatively, you can use finely powdered pumice or rottenstone and linseed oil to create your paste if you are not satisfied with the results from the mixture above. Notice that these ingredients should create a thin paste, unlike the first one. 

Then, use a soft, clean rag to rub the paste on the affected area along the wood grain. Repeat this process until the mark disappears.

You can get all of these items on Amazon or hardware stores near you.

Once the mark is gone, skip the next step and refinish the surface (if necessary), as shown in the final step below. In most cases, your wood will be perfectly okay at this point, and no further action will be necessary. 

Step 3: Remove Moderate Burns with Fine Steel Wool or Sander  

For minor shallow burns that have just barely dug into the wood, you can use steel wool to get rid of the marks. 

Go for the finest steel wool you can find – usually, this should have a ranking of 0000 or 000.

Apply a bit of lemon oil, mineral oil, or any non-drying oil on the steel wool to dampen it and help lubricate its tendrils. The idea is to avoid scratching the wood and risk causing unsightly marks on its surface. 

Scrub the affected area of the wood with the damp steel wool, ensuring you follow the direction of the grain. Rubbing in a different direction other than the grain might cause some damage. 

Observe how the surface changes as you rub, and keep rubbing until the mark is gone.

Get rid of the oil by blotting it dry with a damp clean rag, preferably cotton. Wring out as much water as possible to ensure the cloth is only slightly damp and not soaking wet. 

Also, do not rub the oily surface back and forth as this may only spread it. Instead, gently press the cloth down onto the area and wipe it in a single motion to remove the oil. You may wash the cloth and repeat this process until all the oil is gone. 

The oil should be enough to provide some kind of finish to the affected area. However, if it looks visibly different from the rest of the surface, you will need to refinish it, as we will see in step 4. 

Use a Sander instead of Steel Wool for a Wooden Floor 

Suppose you are working on a floor; use a sander instead of steel wool. Using a sander is also the best way to get paint off of hardwood floors.

To protect yourself, wear a protective face mask before you start sanding. 

Start by sanding down the blemished area using a random orbital sander with 150-grit sandpaper attached – until the burn mark disappears. You don’t want to sand it too deeply; just feather it out until the bare wood is visible.

Ideally, the deeper the damage, the wider you should sand it. Repeat the sanding with 180-grit sandpaper, and then switch to a 220-grit sanding block to fine-tune the surface. 

Be sure to rub along the wood grain each time and not across it, so you do not risk damaging the wood further. 

Once done, use a tack cloth to remove all the sanding dust. We do not recommend using a damp rag in this case as it may raise the grain.

Step 4: Rematch the Finish.

Whether the original finish was paint or something else such as linseed oil or water-based polyurethane, you will want to apply the same product after sanding and cleaning the burned area. 

Most floors have a water-based polyurethane which you can apply by pouring some amount into a bowl or paint bucket and gently applying to the area using a roller or a paintbrush. In any case, the container should have a label with instructions to guide you if it is a different product. 

Whatever it is, be sure to start applying it in the middle as you work it out toward the edges of the area you have sanded.

When refinishing a discolored area, the other thing to keep in mind is to start light and gradually increase the product to match the original color. 

It is way more difficult to lighten an area if you made it too dark. Darken an area should not be nearly as hard.   

To achieve an even sheen, wait for the paint to dry, then spray the area with at least two layers of lacquer. You will need to wait at least an hour for one layer to dry before applying another.

How to Remove Deeper Wood Burn Marks 

Where the wood has sustained much deeper burns, the steps and things you will need for the task will vary slightly from the ones above. 

Here is the list of items you will need: 

  • Epoxy 
  • Hand gloves 
  • Paintbrush 
  • Work cloth or rag 
  • Tung oil
  • Utility knife 
  • Spatula 
  • 120-grit sanding block 
  • 220-grit sanding sponge
  • 80-grit sandpaper 

How to Get Rid of Black Burn Marks on Wood

In this case, you will need to do more than just sand out the weathered area. Restoring the wood will require scraping out the burned wood and then patching up the spot with epoxy. Here are the steps to follow. 

Step 1: Scrape off the Charred Wood Area With a Utility Knife.

The idea here is to remove the deeply burnt area to remain with bare wood. To do so, you will need to gently drag the edge of your utility knife over it in short strokes until the damaged wood has come out. 

Be sure to follow the wood grain, brushing away the scraped debris with a paintbrush as you go. 

Step 2: Sand it with a Fine-Grained Sandpaper

Use a 220-grit sanding sponge to smooth out the groove. Remember to work along the grain so that you do not spread out the damage. 

Again, use a dry paintbrush to clear out the sanding dust. Next, wet a clean rag with clean water, wring it to ensure it is only slightly damp, and use it to soak up and remove the remaining sanding dust in the damaged area. 

Step 3: Restore the Wood’s Color with Tung Oil. 

Allow it to dry, and then use a piece of clean cloth to apply a layer of Tung oil to help restore the wood’s color. If you do not have the oil at home, you can purchase it on Amazon at any home-improvement store in your location. 

You will need to allow the oil to stay overnight so it can soak into the wood. The label on the container should provide you with directions regarding how much oil you should apply. Whatever the case, you should always rub it in along the wood grain. 

Step 4: Fill up the Groove with Wood Epoxy 

Once the wood has absorbed the oil, use a damp rag to wipe away the excess product. 

While the wood is drying, prepare your wood epoxy resin based on the manufacturer’s directions often provided on the label. Consider wearing hand gloves to protect your hands during this exercise. 

Then, use a spatula to feed the epoxy into the furrowed area until it is flush with the rest of the wood surface. 

The label should indicate how long the epoxy takes to dry. Ideally, this should be about 24 to 48 hours. We recommend letting it dry overnight or for more hours but not less before sanding. 

If you have kids or pets, you will want to keep them off the wet item. Otherwise, they might damage the surface before it dries off, and you would have to go over the entire process afresh. 

Step 5: Give it a Final Sanding.

The epoxy cures into a rigid material, so you will require coarse-grained sandpaper to even it out. A disposable 80-grit sandpaper sheet should get the job done. 

Sometimes you may need more than one of these; the abrasive paper can get dull pretty fast due to the hardness of the dry epoxy. 

And, you may have to give the surface several thorough but gentle strokes before achieving the desired smoothness. 

While sanding, take care not to scrape the healthy wood surface around the area that you are repairing. This is where the gentleness aspect comes in.

Once done, consider giving the sanded area a quick once-over with a 120-grit sanding block to make it nice and smooth. 

Step 6: Apply the Same Finishing as before the Burn 

As a final step in this restoration process, you will need to paint or stain the filled burn mark with a matching color and material. This means if it was painted, you would have to find the same paint. If it had a polyurethane layer on, then that is what you will look for.

If you are uncertain how to refinish the part, you may want to have an expert help you figure it out. It is better to pay a bit of cash for the right outcome than spoil what you have created with the wrong finish. 

If you opt to do it yourself, ensure you apply the product from the middle of the repaired area and work it outward – toward the edges of the area you have epoxied.

Also, you will need to start light and gradually increase the product to match the original color. 

If you want a lustrous sheen, you may want to give the surface at least four to five hours to dry, then spray it with two to three layers of lacquer – waiting at least an hour between each layer application for proper dryness.
