Ways To Protect Your Aluminum Park Bench From Rusting

Cast aluminum benches are great for creating a sitting space in your garden. They are sturdy and offer a comfortable sitting experience to read a book or enjoy a sandwich. However, aluminum is prone to rust so maintenance is required to retain quality.

Aluminum outdoor furniture rusts because of oxidation. The combination of moisture exposure and oxygen leads to rust. The ugly-looking brown color gets increasingly worse when left untreated. Therefore, you need to control the spread of rust before it’s too late. In this article, we will share the top methods for combating rust so your aluminum park bench continues to look amazing.

Store away

Don’t leave the aluminum furniture outdoors longer than required. If you sit outdoors daily, then transferring to storage space is not practical. Choose an occasion when it makes sense to place the bench in storage. Here are 3 times of the year when you should place the aluminum bench in storage:

1.   Cold weather

You may not need to use the aluminum park bench for multiple months during the cold seasons. During those periods consider storing it in a designated shed or garage for protection from weathering effects. There is no point in keeping the park bench outdoors when it’s not going to be used.

2.   Vacation

When taking a long vacation it makes sense to store the bench in a garage. It’s not going to be used and heavy rainfall could result in wearing away at the paintwork. However, it depends on the length of your vacation. When going away for a weekend it’s not worth the hassle. 

3.   Rainy months

It’s hard to predict the weather but in some climates, it tends to rain more. For example, if April is typically a wet month, then consider hiding the park bench until May. You are unlikely to use the bench for significant periods when there is too much rain.

It’s easier to store away the park bench when there is a nearby storage unit. You can invest in an inexpensive plastic shed that does a great job of protecting the bench from weathering effects. 

Protective covering

When storage isn’t an option then protective coverings are the next best thing. It can be quicker to cover a park bench than move it into storage. The material type is typically plastic and it protects the bench from rainfall.

Make sure to secure the covering to avoid wind ruining the protection. People are regularly disappointed to find that coverings are blown away from strong wind. Use heavy weights and rope to secure the covering tightly so the wind can’t get an angle to dislodge the unit.

Before covering your furniture it’s important to dry the surface. If it’s raining when you want to apply the covering, then wait until it stops. Make sure the furniture can dry off to prevent moisture from building under the covering. Apart from rust, it can also lead to mold.

Finally, you can use a garden umbrella to provide a roof for the bench. It will come in handy when sitting during rainy days. Also, when the sun is too hot the umbrella can provide protection.

Paste wax

Don’t want the hassle of using coverings? Then paste wax is a viable option that offers water-resistant qualities. It’s commonly used for protecting various metal types against negative weathering effects.

Here is a 3 step process for applying paste wax

  1.   Remove dust: Start by wiping away dust because it will cause issues when applying the paste wax.
  2.     Cloth: Next, use a moist cloth to clean residue that won’t go away with dry options. You may need to scrub hard, but be careful not to damage the paint.
  3.     Apply: Finally, use a paintbrush to apply the paste wax. Wide brushes with fine hairs ensure you can do a good job with just a single stroke in each area. Be thorough so you don’t leave areas prone to rust – especially the corners.

Remove rust

Do you see a buildup of rust on your aluminum park bench? It’s not too late to restore the furniture to its original condition, or something close to it. There is no need to discard your bench before attempting to remove the rust.

Start by scrapping the rust off with a wire grill brush or steel wool. These tools have an abrasive nature that helps remove the rust and expose the layer underneath. However, the coat underneath will not look visually pleasing. You’ll need to apply a fresh coat of paint to restore the visuals of the original.

Consider adding paint to the entire bench to avoid a single spot standing out. It’s more work but the end result will have a better look. In some cases, the rust is so bad that restoration isn’t possible. Then you’ll need to replace the bench with a new one.


Washing your park bench won’t remove rust but it’s a useful prevention method. Over time mildew and grime accumulates on the bench, which can hold moisture. That’s a recipe for rust so you need to clean the bench regularly to remove the dirt.

There is no special method to clean a cast aluminum bench. Using water and soap should do the trick. However, make sure you are thorough by cleaning all the corners where dirt could accumulate.

Avoid using chemicals and metallic brushes that will damage the paint. You can do a lot of damage to the look of the bench with the wrong equipment. Keep it simple by using everyday household cleaning products.  

Final Thoughts

Keeping your outdoor metal furniture from rusting is simple with the right strategies. You don’t have to deal with the hassle of rusty furniture. Using a combination of protective coatings and storage can prevent aluminum furniture from accumulating rust.

The goal is to maintain the durability and visual aesthetic of newly bought outdoor aluminum benches. With the right approach, you can avoid rust for years and enjoy a problem-free sitting experience.
