What is Azek Deck?

Azek decking is a synthetic decking material made from polyvinyl chloride (PVC). It is often used as an alternative to traditional wood decking due to its durability and low-maintenance nature. Azek decking comes in a variety of colors and styles, allowing homeowners to customize their outdoor space. Also, unlike wood decking, Azek does not require staining or sealing to maintain its appearance.

8 Things to Know Before You Start

1) Act Fast

The longer a rust stain sits on your Azek decking, the harder it will be to remove. As soon as you notice a rust stain, take action to prevent it from setting in. While it may still be possible to remove a set-in rust stain, it will require more effort and time.

2) Avoid Harsh Chemicals

When dealing with rust stains on Azek decking, avoid using harsh chemicals like bleach or ammonia. These can damage the surface of your decking and compromise its integrity. Instead, opt for gentler solutions like baking soda and vinegar.

3) Test an Inconspicuous Area First

Before applying any cleaning solution to your entire decking, it’s always a good idea to test it on a small, inconspicuous area first. This will ensure that the solution doesn’t cause any discoloration or damage to your decking.

4) Wear Rubber Gloves

If you have sensitive skin, it’s a good idea to wear rubber gloves while cleaning rust stains from your Azek decking. This will protect your hands from any potential irritation or harsh chemicals. Even if you don’t have sensitive skin, it’s still a good idea to wear gloves as a precaution.

5) Don’t Use Abrasive Tools

Avoid using abrasive tools like steel wool or wire brushes on your Azek decking, as they can scratch and damage the surface. Instead, opt for soft-bristled brushes or sponges to gently scrub away rust stains.

6) Work in Small Sections

To ensure even cleaning and prevent the solution from drying out, work in small sections at a time. This will also help you to keep track of which areas you have already cleaned and which still need attention.

7) Rinse Thoroughly

After scrubbing away the rust stains, make sure to rinse your Azek decking thoroughly with clean water. This will remove any remaining cleaning solution and prevent it from drying on the surface.

8) Repeat if Necessary

If the rust stains are stubborn, you may need to repeat the cleaning process a few times. Be patient and persistent, and eventually, your Azek decking will be free of unsightly rust stains. As always, remember to rinse thoroughly after each round of cleaning.

12 Steps on How to Remove Rust Stains From Azek Deck

Step 1: Mix Baking Soda and White Vinegar

In a small bowl, mix equal parts baking soda and white vinegar to create a paste. This will be your cleaning solution. Also, make sure to put on your rubber gloves at this point if you will be using them. And be sure to have a bucket of water or water hose nearby for rinsing.

Step 2: Wet the Affected Area

Using a water hose or bucket of water, wet the area where the rust stain is located. This will help loosen the stain and make it easier to remove. As an alternative, you can also spray the area with a water bottle.

Step 3: Apply the Cleaning Solution

Using your fingers or a soft-bristled brush, apply the baking soda and vinegar paste to the rust stain. Make sure to cover the entire stain with a thick layer of paste. If using gloves, be sure to work carefully so as not to damage or scratch the surface of your decking.

Step 4: Let It Sit

Allow the cleaning solution to sit on the rust stain for at least 15 minutes. This will give it time to work its magic and loosen the stain from the surface. Then, proceed to the next step while waiting.

Step 5: Scrub Gently

Using your soft-bristled brush or sponge, gently scrub the affected area in a circular motion. This will help to break up the rust stain and lift it from the surface. Be sure not to use too much pressure, as this can damage your decking.

Step 6: Rinse Thoroughly

Once you have scrubbed the area, rinse it thoroughly with clean water. Use a water hose or bucket of water to remove all traces of the cleaning solution and loosen the rust stain. For smaller areas, you can also use a spray bottle to rinse.

Step 7: Check for Remaining Stains

After rinsing, check if the rust stain is completely removed. If not, repeat the cleaning process until it is gone. Depending on the severity of the stain, this may take a few rounds of cleaning and scrubbing.

Step 8: Move on to the Next Section

If the rust stain is completely removed, move on to the next section and repeat steps 2-7 until you have cleaned all affected areas. If not, continue repeating steps 3-6 on the remaining stains. When all areas are completed, proceed to the next step.

Step 9: Rinse Entire Decking

With all the rust stains removed, rinse your entire Azek decking thoroughly with clean water. This will ensure that any traces of cleaning solution or loosened rust stain are completely removed from the surface.

Step 10: Dry and Inspect

Using a clean cloth or towel, dry your decking and inspect for any remaining rust stains. If you notice any, repeat the cleaning process on those areas until they are completely gone. Very stubborn stains may require the use of a specialized rust remover.

Step 11: Clean and Rinse Tools

After you have finished cleaning your Azek decking, make sure to clean and rinse your tools thoroughly as well. This will prevent any residual solution or rust stain from transferring onto other surfaces in the future.

Step 12: Regularly Maintain and Protect Your Decking

To prevent rust stains from occurring in the future, make sure to clean and maintain your Azek decking regularly. Sweep away debris and dirt, and promptly clean up any spills or stains. You can also apply a protective sealant to your decking to help prevent rust and other stains. With proper maintenance, your decking will stay beautiful for years to come. 

So remember to plan ahead, follow these steps on how to remove rust stains from Azek deck carefully, and enjoy your rust-free Azek decking!  Keep in mind that prevention is always better than cure when it comes to maintaining the beauty of your outdoor space. Regularly cleaning and protecting your decking will not only prevent unsightly stains but also extend its lifespan.
