Here are some methods and tips to remove polyurethane from wood without sanding.

Method 1: Using Denatured Alcohol and Lacquer Thinner

I explained this method of removing polyurethane at the beginning, so you can learn from above.

Still, I would like to tell you in short.

Requires: 

• Denatured alcohol
• Lacquer thinner
• Warm water
• Stirring stick
• Vacuum cleaner
• Fine steel wool 00 pad
• Regular paintbrush

Step 1: Prepare to start working

• Clean the surface of the wood and make sure your project should be done in a well-ventilated room.

Step 2: Make a remover by mixing denatured alcohol and lacquer thinner together.

Step 3: Apply the mixture on the surface of the wood to remove polyurethane.

Step 4: Remove the mixture from the wood surface.

Step 5: Clean the wood surface.

Method 2: Remove Poly from Wood with Paint Stripper

Requires:

• Citrus stripper gel
• Vacuum cleaner
• Regular paintbrush
• Plastic scraper
• Regular brush
• Chemical-resistant gloves 
• Chemical splash goggles

Step 1: Prepare the workspace before you start.

• Vacuum the work surface or wipe it down with a clean towel..

Step 2: Apply the stripper.

• Shake the stripper before applying
• Pour the paint stripper in a container.
• Then apply the paint stripper to the workpiece using a standard paintbrush.
• You can use a toothbrush to apply the stripper to the corners.

Step 3: let dry the paint stripper or sock the polyurethane.

• Allow the stripper to work effectively for 30 to 24 hours.
• If you are allowing the stripper to stay on the wood for a long time, then cover the wood with plastic.

Step 4: Scrape the stripper socked polyurethane.

• After 24 hours, scrape off the polyurethane using a scraper.
• Begin to scrape in the direction of the grain of the wood.
• Use a stripping pad if the corner is difficult to reach.

Step 5: Clean the wood’s surface.

• Use a paint stripper wash to get rid of any leftover paint on the wood surface. (Follow the cleaning guidelines.)

Method 3: Using baking soda and vinegar.

Requires: 

• Baking soda.
• Vinegar.
• Vacuum cleaner.
• Regular paintbrush
• Hot water.
• Stirring stick.
• Cornstarch.
• Wire brush or steel wool 00 pad.
• 60, 80, and 120 grit assorted sandpapers (Optional).

Step 1: Get the mixture ready.

Make sure your workspace is prepared and dust-free.

Mix baking soda, cornstarch, and cleaning vinegar together.

• Take an empty container.
• Pour 4 cups of hot water.
• Add 1 cup of cornstarch.
• 1/2 cup of cold water.

When you mix all these things a thick paste will be formed.

• Get another bowl, and fill it with 4 cups of water.
• After this, add half a cup of soda and a tablespoon of vinegar to it.
• Use a stirring stick to combine this substance.
• Then mix this mixture well in the initial mixture prepared by you.

Step 2: Using a standard paintbrush, apply the mixture.

• Apply the prepared mixture with a paintbrush to the workpiece.
• Let it rest for about 5 to 10 minutes to sit in the wood.
• Next, scrub the wood surface with a wire brush or plastic scraper. (Avoid applying excessive pressure because overpressure can damage your wood.)
• Let the surface dry.
  • You can use a hairdryer to dry quickly.

Step 3: The third step is to sand the surface of the wood 

• The purpose of sanding in this method is to prepare the wood for future refinishing, not to remove the polyurethane.
• You can start sanding with the 60-grit sandpaper to bring back its natural color.
  • One crucial point is that you ought to always sand in the direction of the grain.
• Then, sand the wood with 80-grit sandpaper with low pressure.
• For the best effect in the end, you’ll need to sand with 120-grit sandpaper.
• Now clean the wood
  • Then, clean the wood with a dry, clean rag.
  • However you can clean with a wood cleaner or a vacuum to clean.
