Use a chemical paint stripper
Using a chemical paint stripper is an effective way to remove paint from carvings and crevices. Chemical strippers break down old paint or varnish, allowing for easy removal without damaging the underlying surface. They are particularly useful for intricate details and carvings, which often hold stubborn paint and can be challenging to clean.
There are several types of chemical paint strippers available, including soy-based, citrus-based, and methylene chloride-based strippers. Soy-based strippers, such as Soy-Gel and Star 10, are safe and effective options that are derived from soybeans. Citrus-based strippers, such as citristrip, are biodegradable and safe to use on any surface, although they work more slowly than stronger chemicals. Methylene chloride-based strippers are the fastest-acting option but are also the most toxic and should be used with caution. They require proper ventilation and personal protective equipment, including chemical-resistant gloves and an organic vapour respirator.
When using a chemical paint stripper, it is important to follow the correct procedure to ensure effectiveness and safety. First, prepare your workspace by covering the surface with newspaper and ensuring adequate ventilation. Then, apply the stripper liberally with a brush, putty knife, or roller, ensuring that it is thick enough to thoroughly coat the surface. You can also use a layer of wax paper or plastic wrap over the stripper to keep it wet and working longer.
Allow the stripper to work through the layers of paint, which may take about 15 minutes for a few layers and longer for more layers or applications. You will see the paint start to bubble, and after a couple of minutes, you can begin scraping with a metal or plastic scraper to remove the bulk of the paint. Repeat this process as needed, and for detailed areas, use a wire brush or flat-head screwdriver to get into the crevices. Finally, remove any remaining residue by wiping with a damp lint-free rag.
After removing the paint, use a stripper rinse or denatured alcohol to clean the surface and remove any remaining chemical residue. Allow the piece to dry thoroughly before proceeding with any sanding or refinishing.

Try a wire brush
Stripping paint out of carvings and crevices can be a challenging task, but a wire brush can be an effective tool to help you get the job done. Here are some tips on how to use a wire brush to strip paint out of carvings and crevices:
Choose the Right Wire Brush
When selecting a wire brush, consider the type of wire and brush design. The wire type should match the surface material you're working on. For wooden carvings and crevices, brass or nylon wire brushes are ideal because they are adaptable and work well with wood. You can also find wire brushes with different bristle thicknesses. Fine or thin bristles are suitable for light-duty tasks, while medium to coarse bristles are better for extensive external work.
Prepare the Surface
Before using the wire brush, prepare the surface by applying a chemical paint remover or stripper. Look for a product designed for intricate details and cracks, such as a detail stripper. Apply the stripper with a brush, following the manufacturer's instructions. Let it sit for the recommended time, usually around 20 minutes to an hour, until it softens the paint.
Use the Wire Brush
Once the paint softens, it's time to use your wire brush. Work the brush with firm but not harsh strokes, following the direction of the wood grain to avoid scarring the surface. Be cautious when working around delicate areas to avoid damage. If the wire brush seems too stiff, consider using a toothbrush for more sensitive spots. You can also adjust the pressure and opt for a wire brush with softer bristles to minimise the risk of damaging the wood.
Remove Remaining Paint
After the initial wire brushing, there may still be some residual paint in the crevices. Use a toothbrush and water to wash away any remaining paint and stripper from the grooves. Alternatively, you can use a flat-head screwdriver to reach tight spots that the brush can't access. Remember that paint removal can be a tedious process, and some paint may be stubborn.
Finish the Surface
After removing the paint, you can finish the surface by sanding it down to create a smooth base for the next steps. You may also need to stain or refinish the surface, depending on your project's requirements. Don't forget to wear safety goggles and gloves when using the wire brush and other tools to protect yourself from any flying debris or chemicals.

Heat the paint to soften it
Heat guns are an effective way to remove paint from wood. They use heat to soften the paint, causing it to loosen, blister, and bubble, making it easy to remove with a scraper. When using a heat gun, it is important to keep the nozzle about 2 inches away from the surface and move it back and forth until the paint begins to bubble. Stop immediately if the finish begins to smoke. With your other hand, use a paint scraper held at a 30-degree angle to the surface to remove the softened paint.
It is important to note that heat guns generate high temperatures, so it is crucial to keep a fire extinguisher nearby and never leave the heat gun unattended. Additionally, always wear safety goggles and a face mask to protect yourself from the dust generated during the paint removal process.
While heat guns are effective for removing paint from flat surfaces, they may not be ideal for intricate carvings and crevices. In such cases, a combination of methods may be more suitable, such as using a chemical stripper or sandpaper for detailed areas and a heat gun for flat surfaces.
If you are looking for a more environmentally friendly alternative, steam strippers use water vapor to soften the paint without reaching high temperatures, eliminating fire risks. However, this method can generate a lot of moisture and saturate the wood.

Sand the carvings
Sanding is one of the three common ways to strip paint from wood, the other two being heating and chemical stripping. It is important to note that sanding is not always the best option, as it can result in a loss of detail in the carvings.
If you do decide to sand the carvings, there are a few things to keep in mind. First, always wear safety gear, such as eye protection and a respirator, to protect yourself from the dust created during the sanding process.
There are different types of sanders available, such as power sanding disks and clapboard sanders. These are great for large, flat exterior surfaces but may not be ideal for intricate carvings. For smaller areas and corners, you can use a utility knife blade without the handle to carefully scrape the paint away. This method allows you to use the blade at different angles to access tight spaces.
Another option is to use a sanding brush or sandblaster, which can be effective in removing paint without damaging the wood. If you are concerned about losing detail, you can also try using dental picks or sanding cords to carefully remove paint from crevices and tight spaces.
It is important to be cautious and patient during the sanding process, as it can be easy to damage the wood or lose the intricate details of the carvings if you are not careful. Take your time and work in small sections to ensure the best results.

Cleaning the Surface
After removing the majority of the paint with the utility knife, it's important to clean the surface to eliminate any remaining paint residue. Use a stiff-bristle brush or an old toothbrush to scrub the carvings and crevices, removing any leftover paint stripper and paint particles. You can also use a wire brush for more stubborn areas, but be mindful of the pressure applied to avoid scratching the surface.
Finishing Touches
Finally, once the surface is thoroughly cleaned and dried, inspect it for any remaining paint residue in the crevices. If necessary, use the utility knife again to carefully pick out any remaining bits of paint. After ensuring that all the paint has been removed, you can proceed with refinishing the surface as desired.
Using a utility knife to strip paint out of carvings and crevices requires patience and a delicate touch. Always prioritize safety by wearing protective gear, such as gloves and safety goggles, to prevent injuries. Additionally, be cautious of the blade's sharpness and handle the knife with care to avoid accidental cuts. With practice and precision, you can effectively use a utility knife to strip paint from intricate surfaces.
