How to Clean Azek Deck

Can I Use Vinegar on Azek Decking?

No, you should not use vinegar to clean Azek decking. Vinegar is acidic and can cause damage to the material of the decking. Also, using vinegar may leave behind a residue that will attract dirt and grime over time. It is recommended that you only use cleaning products specifically designed for use on synthetic decking materials like Azek.

These cleaners are formulated to be safe for use on the material and will leave your deck looking like new. If you want to avoid using harsh chemicals, a mixture of mild soap and water should also do the trick. Make sure to rinse away any soap residue with clear water after cleaning. Regular sweeping and hosing off of the deck will help keep it looking great and extend its life.

Be sure to check with your Azek deck’s manufacturer for any specific cleaning instructions they may have. Different manufacturers may have slightly different recommendations, so it is best to stick with their instructions when attempting to clean your Azek decking. Additionally, always be sure to test any cleaner on a small area of the deck before applying it over the entire surface.

And finally, never power wash an Azek deck as this can cause severe damage to the material and void any warranties associated with the product.  With proper care and maintenance, your beautiful Azek deck will look great for many years to come! 

9 Methods How to Clean Azek Deck

1. Use a Soft Brush:

The first step is to use a soft brush to remove any loose dirt or debris from your deck. Make sure to use a brush with synthetic bristles, as natural fibers may scratch the deck’s surface. You can also use a bucket of soapy water and a soft sponge to help remove any stubborn dirt. If you don’t have a soft brush, you can use a broom with synthetic bristles. Although not ideal, it’s better than using a natural fiber broom. Make sure to use sweeping motions so you don’t damage the deck’s surface.

2. Make a Cleaning Solution:

Once you have removed all the loose dirt and debris, you will need to make a cleaning solution. You can either use a commercial deck cleaner or make your own using water and dish soap. For the latter, mix one gallon of warm water with one-quarter teaspoon of mild liquid dish soap. Make sure to use a soap that is not overly harsh, as it can damage the surface of your Azek decking. Try to avoid any soap that contains bleach, as this can also damage the decking.

Once the solution is mixed, use a garden sprayer to apply it across the surface of your deck. Make sure to get into all the nooks and crannies to ensure that all dirt and debris is removed. Let the solution sit for about 10 minutes, then scrub with a medium bristle brush to work the dirt out of the grooves.

3. Apply the Cleaning Solution:

Once you have made your cleaning solution, you will need to apply it to your deck using a garden hose or pressure washer. Start from the top of your deck and work your way down using a steady stream of water. Make sure to cover all areas of the deck, including. Any crevices or tight corners.

Apply It to Your Deck

If using a pressure washer, use low to medium pressure and keep the nozzle at least 12 inches away from the deck surface. Be sure not to use a pressure setting that is too high, as it could damage the decking material. Allow the cleaning solution to sit on the deck for 5-10 minutes before rinsing it off.

4. Scrub the Surface:

Once you have applied the cleaning solution, you will need to scrub the surface of your deck with a stiff brush. This will help to loosen dirt, mold, and grime that has built up over time. Be sure to scrub hard enough to get into the grain of the material. If necessary, you can use a pressure washer to help remove stubborn dirt and grime.

Just be sure to keep the nozzle of the pressure washer at least 12 inches away from the surface of your deck. This will help prevent any unnecessary damage to the material. Once you have finished scrubbing the deck, rinse it off with a garden hose or pressure washer to remove any residue.

5. Rinse the Surface:

Once you have scrubbed the surface of your deck, you will need to rinse it off with clean water. This will help to remove any dirt or debris that was loosened during the cleaning process. You can use a garden hose with a nozzle or a bucket and sponge to rinse off the surface. Be sure to get into all of the nooks and crannies as well so that no dirt is left behind.

Allow the surface to dry completely before continuing on with the next step. Additionally, you may want to consider using a pressure washer for large-scale jobs. This will help to break apart any stuck-on dirt and grime with minimal effort.

6. Remove Any Stubborn Stains:

If there are any stubborn stains on your deck, you may need to use a commercial deck cleaner or bleach to remove them. It is important to follow the instructions on the product label, as well as any safety precautions. For example, bleach should always be used with caution and in a well-ventilated area.

Make sure to rinse the deck thoroughly after you have used any cleaning products, as they can be damaging if left on for too long. To avoid damaging any plants or grass near the deck, cover them with a drop cloth before using any chemicals. Once the stain has been removed, use a garden hose to rinse the deck once again and make sure that any remnants of the cleaning products are gone.

7. Allow Your Deck to Dry:

Once you have cleaned and rinsed your deck, you will need to allow it to dry completely before applying any sealers or stains. This can take anywhere from 24 hours to several days, depending on the weather conditions. Make sure your deck is completely dry before moving on to the next step. Additionally, if you plan to use a sealer or stain, make sure you do it on a dry day with no rain in the forecast. This will help ensure that the sealer or stain adheres properly.

Allow It to Dry Completely

8. Apply a Sealer:

Once your deck is completely dry, you may want to apply a sealer to help protect it from future damage. There are many types of sealants available, so do your research to find the one that best suits your needs. After you select a sealant, apply it according to the manufacturer’s instructions.

Depending on the sealant you choose, you may have to reapply every few years or so to keep your deck looking its best. With proper care and maintenance, your Azek Deck can remain beautiful for years to come!

9. Apply a Stain:

If you want, you can also apply a stain to your newly cleaned and sealed deck. There are many different colors and types of stains available on the market, so you can choose the one that best suits the look you’re trying to achieve. Before applying any stain, make sure to read and follow all of the instructions provided by the manufacturer. Once you have applied the stain, let it dry for a few hours or overnight before walking on your deck.

You Can Also Apply a Stain

If you’re staining the railings, be sure to use a brush that is made specifically for applying deck stain and sealer. This will ensure that the railing looks even and professional after being stained. When applying any product to your Azek deck, be sure to wear protective gloves and eyewear to prevent any harm from coming to your body.


By following the correct procedure and using the necessary materials, you can easily clean your Azek deck and enjoy it for years to come.
