Yes, cars with roof racks can go through a carwash, but it's generally not recommended due to the high risk of damage. The safety depends on the type of roof rack (e.g., fixed or removable) and the carwash (e.g., touchless or automatic with brushes). Roof racks are accessories mounted on the vehicle's roof for carrying extra cargo, like bikes or luggage. However, the moving parts and pressure in carwashes can loosen or break the rack, scratch the car's paint, or even harm the carwash machinery.
Why it's risky: Automatic carwashes with rotating brushes or cloths can snag on roof rack components, leading to bends or detachment. Even touchless carwashes use high-pressure jets that might force water into seals, causing leaks or corrosion. For example, manufacturers like Thule and Yakima often advise against it in their manuals to prevent voiding warranties. If you must use a carwash, opt for a touchless one and ensure the rack is securely installed and empty.
Tips to minimize risk: Always remove any attachments like bike racks or cargo boxes before washing. Check that all bolts and clamps are tight. Hand washing is the safest alternative, as it gives you control over pressure and contact. Below is a table summarizing compatibility based on common scenarios:
| Carwash Type | Roof Rack Type | Risk Level | Recommended Action |
|---|
| Touchless | Fixed | Medium | Possible if rack is secure; avoid frequently |
| Automatic with brushes | Removable | High | Not recommended; remove rack first |
| Self-service | Any | Low | Safe if you control the wand |
| Hand wash | Any | Low | Safest option; inspect rack after |
Ultimately, to protect your investment, always refer to your vehicle and roof rack manufacturer guidelines. Regular maintenance checks can prevent unexpected issues.
