Written by Super Cubes | Mar 7, 2025 5:39:20 PM

Everyone loves a good spring cleaning! But spring is also a great time to give your shipping container some TLC. We've got the perfect spring maintenance checklist to get you inspired and started with best practices to keep your shipping container in top shape.

Why Seasonal Maintenance Matters For Your Shipping Container

Taking time for routine cleaning and care helps to prevent rust, corrosion, and long-term damage. Spring is an ideal time to assess your container. Depending on your location, spring can be a very wet time with snow melting or increased rainfall; this can give you an opportunity to identify potential leaks that need to be addressed. Additionally, you will want to assess your container's susceptibility to moisture because you want to ensure your container and what's inside is protected before warmer weather and increased humidity.

Exterior Shipping Container Inspection and Cleaning

✓ Spotting and Preventing Rust

One of the first things to do is to thoroughly inspect the exterior of your container. Go over the surface from top to bottom and check for any dents, scratches, and rust spots.

From here, you'll want to wash off dirt, salt, and debris from winter buildup. If needed, you'll want to apply rust treatment and protective coatings to any rust spots you've found. If you find bigger problem areas, you will want to address them with proper repair techniques

✓ Check Foundation and Placement

Springtime is ideal for checking that the container is on a stable, level surface. Walk around the container and inspect the ground to ensure there has been no shifting or drainage issues after winter. If you discover any problem areas, you may need to adjust support blocks.

✓ Roof and Door Maintenance

Hop on a ladder and thoroughly inspect the roof of your container. Check for any pooled water or weak spots that could cause future problems.

Next, you'll want to look over your container's doors. Check the seals for any cracks or gaps that could lead to drafts and leaks. For maintenance in this area, you'll want to lubricate hinges and locking mechanisms to keep things opening and closing smoothly. 

 

Interior Shipping Container Checkup

✓ Check for Leaks

After inspecting the outside of your container, hopefully, there were no problematic holes or concerns. Whether things are looking good on the surface or you've identified some questionable areas, next, it's time to look inside your shipping container for signs of leaks; check for water stains, damp spots, or rust streaks that may indicate leaks. Carefully look at the roof and corners of your container, as these are common leak points.

✓ Managing Ventilation and Moisture

After checking for leaks, you should have a good idea of whether your shipping container has had adequate ventilation and if moisture buildup is a concern. If you are experiencing issues with moisture and condensation, it may be time to add venting to your container. If you already have vents on your shipping container, ensure they are clear and functioning to reduce condensation. You may also consider adding moisture absorbers or dehumidifiers if humidity is an issue.

✓ Inspect Flooring

Now is also the time to check your container flooring and make sure things are secure and stable. Check for soft spots, warping, or any damage from heavy use.

Inspect and Clean Stored Items or Belongings

Lastly, you'll want to check on the contents inside your shipping container. Make sure items are dry and not showing any signs of mold or mildew. It's a good idea to reorganize the items inside as this can improve airflow and prevent any moisture buildup in tightly packed areas.

Next, it wouldn't be spring cleaning without some actual cleaning! Take a bit of time to tidy up the interior of your container with a good old-fashioned dusting and sweeping.
