Wood glue provides a durable and robust bond. However, it can be challenging to remove from wood if necessary. But don’t worry about that; we have the solution for you. This article will discuss how to remove old wood glue from wood. So follow our guide if you want to do it without leaving any marks, stains, or damage to the wood.
Best Way to Remove Old Dried Wood Glue?
If you use unfinished wood, you can remove dried wood glue by sanding it, as the glue does not sit on the wood. It soaks into the wood. This makes the bond strong. However, if you are using finished wood, using a heat gun or a hair dryer will be the best choice.
Now, as the glue is not just sitting there, as it is soaked into the wood, it will look different in those spots, and the stain will not soak into the wood as deeply because of the glue when you apply wood stain.
You are removing the clogged pores when sanding the wood as you remove the top layer. And this is what you need to do to get an impressive result.
How to Sand Old Wood Glue
Step 1: Get the Sandpaper
Get 150 or 180-grit sandpaper. If you still need to paint the glue, then 180 grit sandpaper should work great. If you start sanding with something like 60, you have to do it again with sand with 80, 100, 120, 150, and 180. So skipping those and using 180 will be a better choice.
Step 2: Sand the Glue
Use an orbital sander to rub the sandpaper along the dried glue. Or vigorously rubbing your sandpaper along the glue with your hand will work too. Keep doing it until you don’t see the glue.
How to Remove Old Wood Glue From Different Types of Wood
Finished Wood
If your wood is already finished, you can heat the glue with a heat gun or a hair dryer to remove it. Follow these steps to do it:
- Use a hair dryer or a heat gun to apply heat to the glue. Make sure not to burn the wood. Just make the glue soft so it can be easy to remove.
- Scrape off the glue using a plastic putty knife. Do not use metal.
Hardwood
It can be a big problem if the Glue spills out onto your hardwood and if it dries in it. Follow these steps to solve it:
- Heat the Glue with a hair dryer or a heat gun.
- Scrape off the soft Glue using a spatula.
- Mix baking soda and hot water, apply them to the wood glue stain, and wait a few minutes.
- Wipe off the unwanted glue stain from the wood using a warm soapy cloth.
Waxed Wood
Removing Glue from waxed wood is quite different from other types of wood. Follow these steps to do it:
- Cover up the stain using an absorbent paper sheet.
- To soften the stain, run a hot iron over the paper. Keep it cool, or it will burn the paper.
Varnished Wood
Varnished wood has a layer that can be damaged easily. This is why you should use a gentle method to remove the glue stains. Here’s how to do that:
- With warm water and a cloth, dab at the glue stain.
- Use cooking oil or white spirits if this does not work. White spirits will be a better choice as they will not affect varnish.
Teak Wood
Because of its fantastic quality and beauty, people often choose teak wood. However, it can also be a victim of glue stains. If you want to remove it, follow these steps:
- With an abrasive sponge and water, wash over the wood glue
- To remove any remaining marks, rub over the stained area using a cotton ball dipped in methylated spirits
- Until the surface is smooth again, sand it with fine sandpaper if there is an uneven surface because of the glue\

Different Ways to Remove Dried Wood Glue From Unfinished Wood
There are many ways you can remove dried wood glue from unfinished wood. Here are some other methods you can use to do it.
Using Chisel
If you are unwilling to remove dried wood glue by sanding, the best choice is to use a chisel. Here’s how to do it:
- Face the bevel side of the chisel up. This way, the chisel will wedge itself underneath the Glue.
- Next, slowly rock the chisel up and down, attempting to wriggle it beneath the Glue. With this technique, you are more likely not to damage the wood.
- Tap the chisel end with the mallet to press it beneath the wood glue. Make sure not to make the chisel dig into the wood.
- Using a chisel will be the best option if you are unwilling to sand.
Scratching
Scratch the glue off with something such as your nails or anything. This is the simplest way to remove dried wood glue. However, it can make unwanted marks or scratches occur in the wood.
Baking Soda
Baking soda effectively removes more prominent glue stains on wood without much effort. To do it using baking soda, follow the steps below:

- Wash the surface with hot soapy water and let it completely dry.
Nail Polish Remover

How to Prevent Glue Messes
It would be better if you could prevent glue messes, so you don’t have to face this problem. Here are two effective ways to avoid glue messes.
Wipe Up The Glue Drips Once Noticing
Before the wood glue dries, wipe it up using a wet rag as soon as possible once you notice it. You may still need to sand the wood if some marks occur. Even if you see it a very a few moments later, there can be enough time for the spots to appear.
Prevent Spilling Out Wood Glue
When you join two planks of wood and it pushes the glue out, wood glue splotches happen. If this happens, it means you are applying too much glue. Apply less glue to prevent this.
