Driving around with a roof box gives extra storage, but when it comes to washing the car, things can get tricky. Some people don’t think twice, while others panic about damaging their roof box or the car. If you’ve ever wondered whether it’s safe to take your vehicle through a car wash with a roof box attached, let’s go over what you need to know.
Is It Safe to Take a Roof Box Through a Car Wash?
The short answer: No, in most cases. You need to know how tall your car is with the roof box on top. Automatic car washes often have a height restriction, and most won’t accommodate vehicles over 7 feet. A typical roof box adds at least 12 to 18 inches to your vehicle’s height, depending on the model.
Even if your car fits under the limit, automatic car washes with spinning brushes or high-pressure sprays can cause problems. The brushes can damage the surface of the roof box, and the fast movement might knock it off if it isn’t secured well. It can also mess with the roof bars and other attachments. You risk having the wash equipment tear at your roof box or even breaking it.
Automatic touchless washes, which use water jets instead of brushes, are a bit safer. But even here, you have to be cautious. The high-pressure jets can still cause issues. It’s also worth noting that some car wash companies explicitly state that they aren’t responsible for damage to external attachments like roof boxes. Always read the car wash’s height restrictions and safety policies beforehand.
Manual Washing: A Better Option?
Washing your vehicle by hand is by far the safest route. This way, you have full control over the process. It’s time-consuming, yes, but it reduces the risk of damaging both the car and the roof box. A lot of roof boxes are made of materials like ABS plastic, which can scratch easily if scrubbed with rough brushes or sponges. Use a soft microfiber cloth instead, along with gentle cleaning agents.
Hand washing is more thorough, and you can easily reach all the nooks and crannies of the roof box and the roof bars. Plus, you can inspect everything up there to make sure it’s all still secure after a long trip.
Are There Any Alternatives?
If you still want to use a car wash but worry about the risks, some places offer self-service bays where you can use a high-pressure washer yourself. That way, you control the distance and pressure of the water. Just be careful not to get too close to the roof box with the water jet, as that can damage the box or loosen its mounts.
Another option is to remove the roof box before washing your car. It’s extra work, especially if you’re in a rush, but it’s worth considering if you’re looking for peace of mind. Be sure to store the roof box in a clean, dry area when it’s off your car, and check it for any wear or damage before reattaching it.
To Wash or Not to Wash?
In most cases, taking your car through a car wash with a roof box attached is risky and not worth the potential damage. Automatic washes can be too rough, and the height restrictions might make it impossible to go through anyway. Your best bet is to remove the roof box before heading to the wash, or opt for hand washing instead.
