Aluminum
Aluminum is a popular material for garden pieces because it is resistant to rust and corrosion.

Steel
Steel is prone to rust and requires regular maintenance. A rust stain can be easily cleaned, but rust may lead to further damage if not addressed.
Stainless steel is a corrosion-resistant metal commonly used in modern-style garden sets. It can be polished to a high shine or finished with a matte look.

Wrought iron is a popular material for patio furniture because of its classic look.
It is durable, strong, and can withstand various weather conditions. But it still needs regular maintenance and upkeep due to its tendency to rust.
Cast Iron
Cast iron is a heavy and durable metal commonly used in classic-style garden furniture. It is long-lasting and can have intricate and ornate designs.
Cast iron is also prone to rust and may require regular maintenance to keep it in good condition.

Painting Metal Patio Chairs and Tables
To paint metal patio chairs and tables, first clean the surface with a wire brush, scraper, or sandpaper to remove any rust or previous paint.
If you need to smooth rusted areas, you might need an orbital sander.
The sander helps smooth out the surface. You can start with a 60-grit sanding disc, then continue with 120 grit.
Before painting, wash down the pieces with a sponge and warm water. Be careful because if there is rust and dust, the paint won’t stick.
Let the piece dry completely before continuing to paint.
Then, apply a rust-inhibiting primer and let it dry.
Once the primer is dry, apply a coat of outdoor metal paint using a brush or spray can (you can also use paint and primer combination products).
Let the paint dry completely before applying a second coat if necessary.
You can also use a paint product that comes with a primer, like Rust-Oleum oil-rubbed spray paint with primer.

Cleaning Aluminum Furniture
Wash the frame with a sponge or soft bristle brush using a mild soap and water solution. Rinse with water and let dry.
Avoid abrasive cleaners, as many aluminum frames have a powder-coated finish. If abrasive cleaners are used, they can take off that protective outer finish.
If your aluminum pieces have a shiny, non-textured finish, use a fine automotive wax to maintain it.
You can apply mineral or baby oil on textured surfaces to prevent dirt build-up and restore the luster.
