There's an unspoken rule of DIY:

One project always leads to another, which leads to another. It's a never-ending cycle really. Whenever we start a project, it always snowballs in 5 more and Andrew hates it. I can't stop thinking about the next thing and he can't stand to think about the next thing until the current thing is finished.

So when we were updating our screened porch, we thought we were almost done. We had almost completed 5 projects without coming up with a single new project to do. Almost.

Then I looked at our fire pit table. It didn't match our new design and colors at all, but I didn't want to build a new one. I looked at the poor table that had already been stained, painted, and sealed three times and insisted that we refinish it.

Andrew didn't like the idea because stripping all that poly usually requires some pretty harsh chemicals. I looked around for natural removal methods and every time I thought I got close to finding one, I realized it really was too good to be true.

So I decided to modify a mild varnish remover that I found from Hunker, but I was going to take out the main ingredient: ammonia.

Did it work?

For us it did! We were able to get 3 coats of poly, paint, and stain off of our fire pit table and start fresh. Fair warning, you might be spending an hour (or several) sanding.

How to remove polyurethane from wood without chemicals

Wish you could build magazine-worthy furniture and decor without a workshop full of expensive tools? Get the Essential Tools Roadmap and find out which tools are essential to DIY and which 3 tools you should start with.

Step 1: create your varnish removal mixture

Boil 4 cups of water and remove it from the stove. Mix together 1/2 cup cold water and 1 cup cornstarch until it creates a thick paste. Pour your 4 cups of water into a bucket and add 3/4 cup baking soda and 1 tbsp of vinegar. Stir it all together and then add in your cold water and cornstarch.

Step 2: put the mixture on your furniture

Cover your furniture with the mixture using a cloth or paintbrush. Let it sit on your furniture for a few minutes.

Step 3: scrub

Scrub your furniture with 3M Heavy Duty Stripping Pads or wire brushes. Don't be afraid to apply some pressure!

When your furniture is no longer feeling slick, you've successfully removed the polyurethane and are ready to sand! Note: you can skip the scrubbing, but sanding is significantly quicker if you do complete step 3. I tried it both ways! If you do skip the scrubbing make sure the mixture is dry to the touch before sanding.

step 4: sand

Sand your furniture using 60 grit sandpaper until the majority of the color is gone and the natural wood is revealed.

Sand using 80 grit sandpaper to smooth your furniture back out. 60 grit will not leave your furniture feeling great, but you will spend a lot less time using the 80 grit than you had to spend on the 60 grit.

Sand using 120 grit sandpaper for a smoother finish. Continue sanding using higher grit sandpaper until you achieve your desired smoothness. We stopped at 120.

Step 5: wipe the surface

Wipe your surface to remove any remaining sawdust. Once the surface is wiped clean, you're ready to refinish your furniture!

Sure, using harsh chemicals probably could've gotten the job done faster, but at what risk? If something says it might burn your skin, I say no thank you!

I would rather put in a little more time and know that I'm not at risk of damaging my skin or breathing in toxic fumes. So there you have it, youcan remove polyurethane from wood without chemicals.
