Jacksonville’s humid summers and frequent rain showers can take a toll on outdoor furniture, especially if it’s not cared for regularly. Even furniture made from cast aluminum, a material known for being strong and weather-resistant, can start to show wear over time. Rust isn’t a common issue with aluminum like it is with iron or steel, but certain conditions can trigger it. When that happens, it can be more than just a visual problem. Over time, corrosion can slowly eat away at the surface, shortening the life of the furniture.
That’s why staying ahead of the problem is worth it. With the right upkeep, cast aluminum pieces can hold up beautifully throughout many Florida seasons. Whether you’re using them for weekend cookouts or just relaxing on the patio after work, keeping them clean and protected makes a big difference. Here’s a simple breakdown of why cast aluminum can still show signs of rust and what steps you can take to keep your outdoor space looking sharp and lasting longer.
Understanding Cast Aluminum and Rust
Cast aluminum is a popular go-to for outdoor furniture for a few good reasons. It’s lighter than iron, handles changing weather better, and doesn’t rust as easily. Still, some homeowners in Jacksonville notice rust-like spots on their aluminum tables or chairs, especially after long stretches of rainy weather. So what’s really happening?
Aluminum doesn’t rust the same way iron does. Technically, rust is iron oxide, and aluminum doesn’t have iron in it. Instead, aluminum develops its own version of surface oxidation called aluminum oxide. That layer actually protects the metal from further damage. But sometimes that protective layer breaks down.
Scratches on the surface, chemical exposure like pool water, or trapped moisture from repeated storms can damage that layer. Once it’s compromised, oxidation can spread quickly—especially in Jacksonville’s humid and coastal environment.
Furniture pieces that mix metals can also be a problem. If your chairs or table frames are joined using steel bolts or fasteners, those can introduce a reaction called galvanic corrosion. Add moisture to that mix, and it can cause rust stains on surrounding aluminum. These spots sometimes start underneath paint or a factory finish, so you may not see anything until the damage is advanced.
Knowing what’s actually happening under the surface is the first step in fixing and even preventing the issue altogether.
Routine Cleaning and Maintenance Tips
A regular care routine can go a long way in keeping cast aluminum looking good year after year. You don’t need professional tools or a lot of effort either. Just a handful of tasks done periodically can protect the finish and stop early corrosion from setting in.
Here’s an easy cleaning routine you can follow:
– Rinse off dirt and loose debris using a hose. This helps clear crevices where moisture and dirt collect.
– Mix warm water with mild dish soap. Skip harsh or acidic cleaners as they wear away the protective layer.
– Use a soft sponge or a brush with gentle bristles to scrub the entire surface. Focus on joints or small corners where water can pool.
– Rinse clean with fresh water and dry the furniture thoroughly using a soft cloth. Leaving water to evaporate naturally could leave spots or lines behind.
– Check for small surface cracks, bubbles in the paint, or places with scratched-off finishes. These are the areas most likely to start corroding.
In Jacksonville, this routine is especially important in spring and summer, when warm rainstorms and high humidity are common. Monthly cleaning is usually good, but during long stretches of storms, moving to bi-weekly might be smart if your furniture is continuously exposed.
Applying Protective Coatings
Once your furniture is clean and dry, applying a protective coating gives you another level of defense. Coatings keep out moisture, dirt, and oxidation. Depending on what look or level of protection you’re going for, there are several types to choose from.
1. Spray Wax: This one is easy and works well for regular upkeep. Just spray it onto the surface and buff it dry with a soft cloth. It creates a thin, water-resistant layer that helps protect the surface from dirt and rain.
2. Clear Lacquer: For longer-lasting results, consider clear lacquer. It gives a smooth, glossy finish that holds up well in rough weather. Apply it in thin, even coats and let each one dry completely. Doing this outdoors or with plenty of ventilation is best.
3. Polyurethane Sealant: If you want maximum protection, polyurethane is a heavy-duty sealant that forms a strong barrier over your furniture. It’s thicker and longer lasting, making it ideal for Jacksonville’s moist and salty air. Apply it with a brush, and let it dry fully before placing the furniture back outside.
Be sure to only apply coatings to a clean, dry surface. Otherwise, you’ll be trapping dirt and moisture beneath the top layer. Re-coat the furniture about once a year, or more frequently if you see the finish wearing thin. And don’t forget to inspect the seal every few months, especially after harsh weather.
Seasonal Storage Solutions
Jacksonville’s climate changes throughout the year, and giving your furniture proper storage during those shifts helps prevent long-term damage. Protecting your pieces from extreme moisture or bright sunlight adds years to their life.
Here’s how to adjust your storage depending on the season:
– Spring and Summer: These months are full of Florida sunshine, but UV rays can still fade finishes while rain brings surprise corrosion. Use a breathable furniture cover with UV protection when not in use. Make sure it’s not trapping moisture underneath.
– Autumn: Falling leaves and cooling nights aren’t too harmful on their own, but soaking wet leaves sitting on metal can trap water. Protect your furniture with waterproof covers and keep yard debris off.
– Winter: Though North Florida doesn’t freeze often, colder months still bring wet conditions. When possible, store outdoor furniture inside a shed or garage. If you don’t have the room, invest in durable winter weather covers that are made for moisture control.
Place rubber or plastic leg risers under the furniture if storing outdoors, so water doesn’t pool around the legs during rain. Periodic checks help too, just to make sure everything’s staying dry and intact.
