First, use plastic sheeting to seal off everything you don’t want to strip. Next, apply a thick coat of deck strippers to the stained deck boards. After about 30 minutes, remove the old stain and stripper residues off your wood using either a firm-bristled brush or pressure washer.
How To Remove Solid Stain From Wood Deck – The Methods
By the time you are done reading this post, you will have learned the three simple removals of solid stains from your wooden deck.
With age comes the need to refurbish wooden decks. Even the most maintained surfaces will eventually need a total overhaul or a repaint at some point.
An old stain needs to be removed instead of coating it with another layer of stain. If you ignore the stripping stage, the new stain will develop bubbles and blisters since the protective stain film no longer keeps the molds and moisture at bay.

- Stain stripper ( here are the best wood stain removers that I recommend)
- Wood deck brightener
- Paintbrush or roller or sprayer (best applicator for stain)
- Tarps or plastic sheeting
- Protective gloves
- Protective boots

Removing Solid Deck Stains Using A Pressure Washer
A pressure washer, also referred to as a power washer, is a powerful tool you can use to remove solid stains from your wood deck. However, keep in mind, a pressure washer can damage your wood or even masonry if mishandled.
Remove all the movable deck furniture from the deck—tape and seal off flowers or grass on the deck sides. Also, cover the siding using a plastic sheet to minimize accidental damage to it.
Ensure you are wearing your protective boots to protect your feet from the water pressure and avoid slipping. Keep away pets and children from your deck when the power washer is on.
Try and maintain a steady position and distance between the washer nozzle and the wood surface. Then, proceed following the outlined steps below.

Step 1: Begin determining the type of wood on your deck, whether softwood (Pine or Cedar) or hardwood (Oak or Mahogany).
Step 2: Once you have that part figured out, you need to know the correct water pressure to use. Use a water pressure range between 500 to 600 psi (pounds per inch square) for softwood. For hardwood, a pressure of 1200 psi is sustainable.
Step 3: Ensure your pressure washer nozzle has a rotating fan covering a 40-60 degree stretch. This will cover a large surface at a time while you pressure wash your deck boards.
Adjust the water pressure to more or less depending on how effective it is at removing the stains.
Step 4: Hold the pressure washer wand about 12 inches away from the surface, release the trigger and use sweeping motions to sweep away the old and flaking stains from your deck. Sweep along the direction of the wood grain.
Step 5: Gradually work on a section until you manage to remove all the solid stains from the deck.
If they’re stubborn stains, don’t overspray the part in an attempt to fluff them out. You might end up damaging the wood.
Step 6: Allow your wood deck enough time to dry and expose any stubborn stains. Here’s a guide on how long does deck stain take to dry.
Proceed to use a deck stain stripper once the wood has had adequate time to dry up. Then, use the steps in the next section.
Removing Solid Stains Using A Deck Stain Stripper
A stain stripper is most likely going to lift off any stubborn stains from your wood deck. It is a chemical product you can use when pressure washing alone isn’t enough to strip wood deck stains.
You have to remember to wear your gloves before handling this chemical product. However, it is good enough you are working on an outdoor project.
Also, seal off everything you wouldn’t want to come into contact with this stripper. A plastic sheet and tape will do the job well.
Topmost important rule: read and follow the manufacturer’s instructions to the letter for best results.

Step 1: Apply a thick coat of the stripper onto the stained deck. You can use either a paintbrush, a roller, or a pump sprayer. Whichever tool you use, ensure you cover the stains sufficiently.
Step 2: Allow the deck stripper to sit on the surface for bout 20 -30 minutes (or more) based on what the specific product you use states. If the stripper dries up fast, moisten it using a spray bottle.
Step 3: Scrub away the softened stain from the wood using a firm-bristled brush with a bucket of water. This method can be messy and have your brush clogged with stains and strippers. Have plenty of water to rinse out the brush as you go.
Step 4: If you don’t enjoy the tedious work in step three, then go ahead and use a pressure washer. Hold the pressure washer wand at 12-inches above the wood surface, release the trigger and wash away the loose stains from the surface.
Step 5: Use sweeping motions following the wood grain for best results. Don’t concentrate the washer on the stain if you have any stubborn stain because you risk damaging the deck boards.
Step 6: Mop away the excess water to speed up the drying process.
Step 7: If you have stubborn solid stains left, you can repeat the steps above once the wood fully dries.
You can also use a random orbital sander to eliminate every lingering stain from your wood. Set up your sander for painting and begin sanding using a coarse-grit sandpaper. Finish with fine-grit sandpaper to buff the wood once you no longer have any stains left on the wood.
If you have handheld sandpaper, the method is the same. Wipe the wood surface with a damp cloth to eliminate the dust particles.
Let the wood dry well, then finish it with your choice of deck stain. For recommendations, see our best stain for pressure treated wood deck guide.
Removing Solid Stains Using Wood Deck Brightener
Expect your wood deck to look a bit aged and rustic after stripping the stains using a stain stripper and pressure washer. It is normal and can be fixed; you don’t need to panic.
You may ask why your wood looks dull and old after stripping. This is because the deck stain stripper contains a chemical that raises the PH level of the wood, thus making it darker.
A wood deck brightener is meant to correct that PH imbalance and restore the initial wood color. Its main component being oxalic acid and oxygen-rich formulas, which neutralize and maintain the PH levels of the wood.
Wood deck brightener might come in mixed formula or powder form, requiring you to mix it with water. Whatever the form in which they come in, follow the specific instructions of using it.
Remember to wear your heavy-duty gloves, goggles, and protective boots before you begin the heavy-duty task at hand.
You can use a pump sprayer to cover a large surface within a short time. You can get the same results if you use a paintbrush to apply the deck brightener.
The following section is a step-by-step guide on restoring your wood’s natural tones using a deck brightener.

Step 1: Apply a coat of the deck brightener to your wood. It opens the wood pores, making it ready to soak in a new coat of stain.
Step 2: Rinse your deck with water.
Step 3: Allow your deck to air dry completely for a minimum of 48 hours before you proceed to re-stain it. Your wood will look as you pictured it, brightened.
If you stain your wood before it completely dries, you will have color and stain strength inconsistencies.
Here’s a trick to test if the wood is sufficiently dry: spray a little bit of water to an inconspicuous part. If it seeps into the wood, it is dry, and you can proceed and stain it. However, if it forms a puddle and takes a while before soaking into the wood, give it more time to dry.
