If you’re an outdoor enthusiast, a family with children and pets, or a business owner, a roof box can provide a plethora of benefits for your travels. It can give you extra storage space, keep your belongings secure, and improve your car’s aerodynamic design. However, like any other item, a roof box requires maintenance and cleaning to prolong its lifespan. In this article, we’ll guide you through the steps you need to take to keep your roof box in top condition.

Types of Roof Boxes and Materials

Before we delve into the cleaning and maintenance process, let’s first understand the different types of roof boxes and the materials used to make them. There are two main types of roof boxes: hard shell and soft shell.

A hard shell roof box is made of durable materials such as ABS plastic or fiberglass. It’s a sturdy and heavy option that can withstand harsh weather conditions, making it ideal for long trips.

On the other hand, a soft shell roof box is made of lightweight and flexible materials such as nylon or polyester. It’s a great option if you need to pack it up and store it away when not in use, but it may not be as durable as a hard shell roof box.

Maintenance and Cleaning Process

Step 1: Removal and Storage

Before you begin cleaning your roof box, you need to remove it from your car and store it safely on a flat surface. If you have a hard shell roof box, you may need someone to help you lift it off your car. If you have a soft shell roof box, you can easily fold it and store it away.

Step 2: Measuring for Fit and Weight Limit

Before you start cleaning, make sure you measure your roof box to ensure it fits your car’s roof and doesn’t exceed the weight limit. You can find the weight limit in your car’s manual or on the roof box itself. Overloading your roof box can damage both the box and your car’s roof.

Step 3: Cleaning the Exterior

To clean the exterior of your roof box, use a mild detergent and warm water. Avoid using harsh chemicals that can damage the surface or strip the paint off. Gently scrub the surface with a soft brush or cloth, then rinse with water and let it air dry.

Step 4: Cleaning the Interior

To clean the interior of your roof box, remove any dirt or debris with a soft brush or cloth. If you have a hard shell roof box, you can use a vacuum cleaner to remove any dust or sand particles. If you have a soft shell roof box, you can hand wash the interior with a mild detergent and warm water.

Step 5: Securing Belongings and Weight Distribution

After cleaning the interior, make sure you secure your belongings properly and distribute the weight evenly. You can use packing cubes or dividers to keep your items organized and prevent them from shifting during transit.

Step 6: Installation and Noise Level

When installing your roof box back onto your car, make sure you follow the manufacturer’s instructions and use the proper mounting system. A roof box that’s not installed properly can create noise and drag during transit.

Step 7: Repair and Replacement

If your roof box has any cracks or damages, it’s important to repair or replace it immediately. A damaged roof box can compromise your safety and the safety of others on the road.


Maintaining and cleaning your roof box is crucial to prolong its lifespan and ensure your safety on the road. By following these simple steps, you can keep your roof box in top condition and enjoy all the benefits it provides.
