How to Clean a Shipping Container: 4 Easy Steps to Follow

Proper cleaning and maintenance can keep a shipping container in great shape for decades, whether it’s being used for storage, a man cave, or a workspace. Just like a car or home, taking care of your container will prevent rust, corrosion, and other issues, ensuring it stands the test of time. Here’s an easy, step-by-step guide to cleaning and maintaining your shipping container.

Why Clean Your Shipping Container?

Cleaning a shipping container, especially if it’s used, removes any dirt, dust, and contaminants it may have accumulated during transport or while sitting idle. Over time, weather exposure can lead to rust, and without maintenance, even a small patch of rust can expand and damage the container. Regular cleaning and inspection can help avoid costly repairs down the line.

4 Simple Steps to Clean Your Shipping Container

1. Sweep Out the Interior

Begin by sweeping the inside of the container to remove dirt, dust, and debris. Wear a dust mask to protect yourself from any airborne particles. Clearing out the dirt first makes the washing step more effective.

2. Wash Inside and Out

For a thorough clean, wash both the interior and exterior with water and mild detergent. A pressure washer can make this job faster, but be sure to wear eye protection. Start from the top, washing the roof first to ensure dirt flows down and off the container. For the interior, you might also consider a dry ice blast, which removes chemicals and grime without excessive water use.

3. Remove and Treat Rust Spots

Regular rust inspections are essential. Small rust spots can be cleaned with a wire brush and treated with vinegar, which helps stop the spread of rust. Then, paint over the affected area to protect it. For larger rust patches or holes, apply heavy-duty sealant or have a piece of steel welded over the area. Check for daylight shining through any part of the container other than vents, as these areas need immediate attention.

4. Inspect and Remove Other Substances

Look out for any sticky substances, sap, pollen, or insect residue that may have settled on the container. Be vigilant for water seepage, as moisture can lead to mold and mildew. For containers going through U.S. Customs, contaminants like seeds, bugs, and liquids can cause delays, so make sure to thoroughly check and clean.
