Roof Box Maintenance Tips: How to Keep Your Roof Box in Perfect Condition

Cleaning Tips for Roof Boxes

Proper maintenance and cleaning of your roof box can significantly extend its lifespan and maintain its aesthetic appeal. Here are some key tips for cleaning roof boxes without causing damage:

• Use Mild Soap and Water: A gentle solution of mild soap (like dish soap) and warm water is the safest option for cleaning your roof box. Avoid harsh chemicals or abrasive cleaners that can scratch or degrade the plastic.
• Non-Abrasive Cloths: Use a soft sponge or a microfiber cloth to clean the surface, as these materials won’t scratch the box. Avoid using scouring pads, which can create fine scratches that are visible over time.
• Avoid Alcohol and Solvent-Based Cleaners: Products containing alcohol, acetone, or other solvents can damage the plastic by breaking down its protective coating, causing it to become brittle over time. Always check cleaning product labels to ensure they are safe for use on plastics.
• Dry Thoroughly: After cleaning, ensure the roof box is completely dry before storing it. This helps prevent mould or mildew from developing inside.

Storage Guidance for Roof Boxes

Proper storage is essential to avoid unnecessary damage to your roof box. Here are some guidelines:

• Store Horizontally: Always store your roof box horizontally, ideally resting on its base. Storing the box upright or on its side can cause warping, damage to the hinges, and uneven pressure on the locking mechanisms. Using an item such as the Thule MultiLift can help with storage without sacrificing floor space.
• Use a Dry, Shaded Area: A garage or a shed is the best place to store a roof box. It’s important to avoid direct sunlight, as UV rays can weaken the plastic and cause fading. Prolonged exposure to high temperatures can lead to warping, while freezing temperatures can make the plastic brittle and prone to cracking.
• Avoid Outdoor Storage: If indoor storage isn’t an option, ensure the box is covered and protected from extreme weather conditions. Direct exposure to rain, snow, or extreme sun can drastically reduce the lifespan of the box. We have the following covers available depending on the size roof box you own:

Regular Inspections

Regular checks are essential to ensure your roof box remains functional and secure:

• Inspect Locking Mechanisms: Before each use, check that all locking mechanisms are working properly. Look for signs of wear, rust, or damage. A damaged lock could compromise the security of your roof box during travel.
• Check Hinges and Struts: Ensure that the hinges and struts that support the lid are in good condition. These components are crucial for the box to open and close smoothly and safely. If they become loose or damaged, it could lead to lid failure while on the road.
• Examine the roof box for any physical damage: If your roof box has weathered and become weak or brittle, inspect it for cracks or signs of wear. This will help keep the contents dry during rain. It is possible to repair hairline cracks using fibreglass with a competent individual, larger surface damage will be a lot harder to repair and will require a professional to repair it with fibreglass and car body filler, however this could be extremely costly where replacing the roof box would be a more practical solution.

By following these cleaning, storage, and inspection tips, you can ensure that your roof box remains in excellent condition for years to come.
