Outdoor metal furniture is a stylish and durable addition to any garden, patio, or backyard. However, exposure to weather elements can cause metal furniture to rust, deteriorate, and lose its aesthetic appeal. Rust not only wreaks havoc on metal furniture but also poses a health risk to users. Inhaled rust particles can cause respiratory issues, and cut injuries from rusted metal can lead to tetanus. Therefore, it is essential to protect your outdoor metal furniture from rust and maintain its integrity and beauty.

Prevention measures

Prevention is the most effective way to keep metal furniture from rusting. Before exposing your metal furniture to the outdoors, consider applying a rust-resistant coating such as oil, paint, or varnish. These coatings create a barrier between the metal and moisture, air, and other rust-causing elements. Moreover, avoid placing metal furniture in areas with high humidity, near the sea or pool, or under trees and shrubs. High humidity and saltwater can accelerate rusting, while trees and shrubs can hold moisture against the metal surface.

Cleaning and maintenance

Even with preventative measures in place, some metal furniture will inevitably get damaged and rust over time. Hence, it is essential to clean and maintain your metal furniture regularly to prevent further rusting. Begin by using a stiff-bristled brush to remove any rust on the furniture's surface. Avoid using wire brushes or sandpaper as these can scrape off powder finishes or coatings. Once free of rust, wash the furniture with soapy water and rinse with clean water. Dry the furniture thoroughly to prevent moisture from accumulating on the surface. Additionally, apply a coating of rust inhibitor to the furniture to prevent further rusting.


If you have space, it is best to store your metal furniture indoors during the rainy and winter seasons. However, if indoor storage is not an option, you should cover the furniture with a waterproof cover specifically designed for outdoor furniture. The cover will protect the furniture from snow, rain, and moisture, which can cause rust.


Outdoor metal furniture can last for years with proper care and maintenance. Prevention measures such as rust-resistant coatings, proper placement, and regular upkeep, can significantly extend your furniture's lifespan. Remember to clean the furniture regularly, store it indoors or cover it during harsh weather conditions, and apply a rust inhibitor to prevent further rusting. By taking these measures, you will not only protect your furniture but also prolong its beauty and function.
