1. DEFY Exterior Wood Stain Stripper – Easy to Use

This one is a little more convenient, and it offers good performance at a price that is hard to beat. While it may not be the strongest on my list, it is a great choice for most jobs.

Made For Convenience

The main selling point of this product is the fact that it’s easy to use. There’s no mixing or measuring, you just put it into a pump sprayer and go to work. It only takes about 30 minutes for this cleaner to do its work, so there will be less delay.

The Problems

This one doesn’t work on paint, and it won’t remove certain film-type finishes, either. That’s kind of surprising because the warnings on the label indicate toxicity. With such harsh chemicals, you would expect this one to be a little stronger.

Pros
Cons
  • Somewhat toxic
  • Doesn’t remove paint or certain coatings

2. Florida Laboratories Oxalic Acid Crystals – The Hardcore Stripper

If you want to skip all the fillers, you can always just buy pure laboratory-grade oxalic acid. Florida laboratories makes some of the best, and each bag is guaranteed to be 99.6% pure.

Value And Versatility

When you are mixing the solution yourself, you can customize its strength to fit the job. For jobs that don’t require all that much power, you can save some material by mixing it weak. For harsh jobs, you can make it extra-strong (within reason, of course).

The other big advantage of this product is value. On a cost-per-gallon basis, this is one of the cheapest products on the list. So, it may be a little more difficult to use, but it will definitely save you some money.

The Problems

There is only one problem here: Pure oxalic acid is pretty corrosive. It’s not as bad as sulfuric acid or nitric acid, but it can do some serious damage if handled improperly. Always use gloves, goggles, and breathing protection when using this stuff. Very important point: Make sure to keep it away from your children and pets!

Pros
  • Cheap stain remover
  • Lab-grade purity
  • Mixing allows an opportunity for customization
  • Removes any kind of stain
Cons
  • Somewhat dangerous to use
  • Hazardous to pets and small children

3. Woodrich Extreme Solutions EFC-38 Wood Cleaner – Top Stain Remover for Difficult Jobs

As the name of this stripper implies, it is meant for the toughest of jobs. This is the “big gun” that you can break out for those occasions when nothing less will do. It is strong enough to get rid of mold, mildew, old paint, rotted wood, and most other problems.

Strength And Safety

The best thing about this stain remover is the fact that it provides plenty of cleaning power without the use of overly dangerous chemicals. Of course, you don’t want to get too careless because there are still a few warnings on the package. Still, this product has a rare combination of strength and safety.

The Problems

This one is sold as a powder, which means that it has to be mixed. This adds an extra step, but the price is a bigger problem. This is the most expensive product on our list by a significant margin.

Pros
  • Very strong cleaner
  • Mixing allows you to customize the results
  • Environmentally friendly
  • Works well on grayed wood
Cons
  • One of the most expensive removers on the list

4. Restore-A-Deck Wood Stain Stripper – The All-Around Choice

This product offers a mix of versatility, strength, affordability and safety. If you aren’t sure what you need, a product like this is your best bet. With a little experimentation, it should be able to handle any deck stripping job.

Cheapest Per Gallon

On a cost-per-gallon basis, this one offers the lowest price. Of course, your cost will vary depending on how strong you mix your cleaning solution. This product gets pretty good coverage, so you shouldn’t have to mix too much at one time.

The Problems

The only problem I see here is the fact that this product might be a little more dangerous than advertised. It is “eco-safe” in the sense that sodium carbonate (its main ingredient) is found in nature. Thus, it doesn’t pose a huge threat to the environment. However, the crystals and the solution can still pose a threat to you.

Pros
  • Very cost-effective
  • Relatively eco-friendly
  • Strong enough for any job
  • Won’t interfere with staining when wet
Cons
  • Not as safe as advertised

5. #1 Deck Wood Stain Stripper – Very Convenient

This one is probably the most convenient option we’ve seen. It’s a simple and ready-mixed product much like the “Defy” stripper we looked at before.

Specialized For Deck Staining

This product is meant for those who are planning to stain their deck, and it does a great job in that department. It brings out the color and grain of the natural wood while removing that ugly old finish. Best of all, it will help the stain to adhere a little better to the surface.

The Problems

Like many of the cheaper choices, this product isn’t all that strong. It won’t remove paint, and certain coatings can also give it a hard time. On top of that, the coverage is only about 100-150 square feet per gallon, which isn’t that great.

Pros
  • No fancy gimmicks, just an effective product
  • Helps wood stain to “stick” better
  • Brings out the woodgrain
  • Very low cost
Cons
  • Coverage isn’t great
  • Will not remove paint

Buyer’s Guide

Now let’s go a little deeper into the subject and educate you about these products. Only in this way can I help you to choose the best one.

Why Use A Wood Stain Remover?

At this point, you might be wondering why you would choose to use a wood stripper. The obvious answer is convenience. You could use some other method, but this really is the easiest way to go.

Scrapers are too slow and too much work, so they are clearly inferior. Even with the use of a heat gun, you are looking at hours of work. You could use a power sander or some other rotary grinder, which is also pretty fast. However, you are going to have dust and paint chips flying everywhere. This creates a breathing hazard and makes cleanup more of a pain.

Types Of Wood Stain Remover

There are many different ingredients that can be used in these products, so this isn’t a simple subject. While many different things are used, all wood stain remover/stripper products will work in one of the following ways.

Solvent

Solvents work by chemically dissolving the old finish. Examples of solvents used in wood strippers would include methylene chloride, alcohol, acetone, and toluene. One of the main advantages of this type of product is extreme cleaning power. These are some of the only wood stain removers that can dissolve old paint. However, these also tend to be the most toxic products as well.

Caustic

Caustic strippers work by dissolving the finish and converting it into some other substance. Strong caustic cleaners are very popular for wood stripping, even though they require a little more care. These are usually strong acids or bases, both of which tend to be corrosive. Examples of caustic agents used in wood strippers would include oxalic acid and lye (sodium or potassium hydroxide). These substances are the harshest option, but sometimes that is what you need.

Biochemical

These products attempt to get the best of both worlds by using chemical substances that are less refined. By using more natural ingredients, manufacturers attempt to create alternative wood strippers that will be safer to use and easier on the environment. Examples of biochemical agents used in these products would include citric acid, soy oil, lactic acid, wood-pulp extract, and various terpenes.

Conclusion

After buying your wood stain, you might be in a rush to get started. However, I would advise you to take your time and remove the old finish thoroughly. Whichever of these products you choose, you will probably get good results. The extra time and care will result in a level of beauty that pleases both the eye and the soul. I hope you have enjoyed this article and that you will come back to enjoy more of our work.

    • Yes, wood stain remover should work to remove wood stain gel. If not you can always use paint stripper. To help it come off even easier I would use a stiff-bristled scrub brush and wipe off the softened stain with a rag.

  1. I recently stained my new pressure treated cedar deck. In a rush to “get things done” I did not test a small area but instead just went for it. I used a semi-transparent timber oil stain hoping for a deep walnut color. The next morning I have a bright red deck. Is there a waiting time between staining and stripping? I think of coloring my hair and know to many chemicals in a short amount of time can cause damage which I would like to avoid here. The railings have not yet been stained, is there a way to get the wood back to natural so that when I stain again there is not an obvious different between pre-stained areas?

    • I would wait for the stain to dry before stripping it but it might be easier to do it while it is still somewhat wet. I would test it in a small area before doing the whole deck. If you are looking for a good stain stripper, I would recommend this stripper by SaverSystems on Amazon.

  2. Hi William,

    We just had a new cedar fence installed and the grass company sprayed our grass before we could seal it. Now there green spray stains all along the fence. What product would you recommend to remove the stains before sealing? Thank you.

  4. I just had someone apply a solid stain to my porch and the color is atrocious. The porch had been previously stained with semi transparent which had worn off, and was sanded and washed in preperation. What’s the best product to remove the two coats of fresh, solid stain so that i can start over?

  5. I just applied a Perma-chink lifeline acrylic finish to the interior of my log home and now my wife decided to have me remove it for a different color. I began sanding with 60 grit sand paper and an orbital sander but it took almost 2 hours and 3 sanding disks to do a 8″ by 32″ area. What is the best remover for freshly stained yellow pine with an acrylic finish?
    (I know this would be easier than talking my wife into keeping the color)

    • Hi Russell,
      To have a happy relationship listen to your wife (especially when it comes to home) 🙂
      The problem with removing varnish or paint is that the paper fills with sandpaper very quickly, especially when the paper is new or soft in nature.
      You have several options for action: Paint and varnish remover such as this one by Dumond.
      Once you remove 80-90% of the coating, your wounding will become much easier.
      Follow the manufacturer’s instructions and remove the grass chats with the spatula without damaging the wood.
      The staining of the wood (which has soaked into the wood) will not be removed from the preparation, only with sandpaper.
      There are special angle grinder discs that have a porous structure and are harder to fill (here’s a recommended disc).
      Be careful to use it only on straight areas (the edges can be easily rubbed), keep the disc parallel to the surface to avoid unwanted distortions on the surface.
      There is another old trick, but here, too, you must be careful not to overdo it. You put an acetone-soaked cloth on the surface and then cover it with stretch or nylon for a few hours.
      The procedure is similar to the paint remover.

  6. I was curious, why everything else is suggested for use, except for the product that is recommended as #2, the Oxalic Acid. I was wanting to purchase that product for removing the stain on my deck, but lack confidence since it is not mentioned when people are requesting opinion of what to use for removing stain on their decks.

  7. I am trying to strip the strain from wood panels in my home but having no luck with the stripper I used for the paint.
    It has to stick to the wall to remove it properly but not sure what to use

  8. Hi William!
    Thanks for this great article. I have been trying to strip a vintage wood chair that was covered in very dark stain. I have been using oxalis acid and it is working…. but I think I’m on the 5th or 6th application and there is still faint staining. Am I doing something wrong? Do you have any tips for better application? I have tried increasing the strength of my mixture but I’m having weak results even with the increased dosage.

    Please help!

  9. Any suggested brands to remove the staining on 80 year old living room flooring? My dogs recently spilt a container of white paint primer on my floor. So I need something with stain and paint power. There are so many choices and they are all so confusing.

    This house was built by my great grandfather so I don’t want to ruin the condition of the floor itself. Thanks.
