As a homeowner or business owner, you may have invested in a shipping container for storage or other purposes. These sturdy and reliable containers offer a cost-effective solution for various needs, but they do require regular maintenance to ensure they remain in good condition. Properly maintaining your shipping container is crucial for protecting your investment and extending its lifespan.

 

Here are 5 tips for properly maintaining your shipping container:

 

1. Keep it Clean

 

Shipping containers are exposed to various weather conditions and can accumulate dirt, dust, and debris over time. Regular cleaning is essential for maintaining the appearance and functionality of your container.

 

Start by removing any visible dirt or debris from the exterior of the container. Use a pressure washer or hose to rinse away stubborn dirt, and then scrub away any remaining grime with a soft brush or sponge.

 

If your container has compartments inside, be sure to clean the interior as well. This may include sweeping or vacuuming the floor and wiping down all surfaces with a mild detergent.

 

2. Prevent Rust

 

One of the biggest challenges facing shipping containers is rust. While these containers are made with weathering steel (Core-ten steel), which is designed to only develop surface rust, exposed metal is still susceptible to rust in damp environments. If you notice new deep scratches or dents that expose the metal, simply clean the area and apply a coat of exterior paint to the exposed section.

 

If rust has already formed on the container, you can remove it with a wire brush or sandpaper. After removing the rust, be sure to apply an exterior metal paint to prevent the rust from returning.

 

3. Repaint as Needed

 

To prevent rust, shipping containers are typically coated with a layer of exterior metal paint. However, over time, the paint will wear down, leaving the container vulnerable to rust and other damage.

 

To protect your container, repaint it as needed. This may involve pressure washing the container's surface to remove dirt, loose paint, or rust before applying a fresh coat of paint. Be sure to use paint specifically designed for shipping containers to provide the best protection.

 

4. Repair any damage

 

Shipping containers are designed to be robust and durable, but damage can still occur over time. If you find any holes or other damage to your container, be sure to repair it as soon as possible. Small holes can be easily repaired using ISO-certified repair patches, which are easy to use and provide a long-lasting solution.

If the damage is too extensive to repair yourself, you may need to hire a professional for repairs.

5. Prevent pest infestations

 

Containers are often used for storage and can attract pests such as rodents and insects. To prevent pests from making your container their home, be sure to keep the container clean and free of food and other items that attract pests.

 

If you find signs of pests, be sure to address the problem as soon as possible. This may include using traps or other pest control methods to eliminate the pests, and then taking steps to prevent them from returning.
