Can Tonneau Covers Go Through A Carwash?

Yes, tonneau covers can go through a carwash, but it depends on the type. Soft covers (vinyl or canvas) may get damaged. Hard covers (aluminum or fiberglass) can usually handle it. Check manufacturer guidelines for specifics.

Factors To Consider Before Taking A Tonneau Cover Through A Carwash

Evaluate the Carwash Type:

Not all carwashes are created equal, and their design can significantly impact the compatibility with tonneau covers.

There are primarily two types of carwashes: touchless and friction-based. 

Touchless car washes use high-pressure water and cleaning agents, while friction-based carwashes employ rotating brushes or cloth to clean the vehicle.

Determine the type of carwash you plan to use and assess how it might interact with your tonneau cover.

Verify Water Resistance Features:

Different tonneau covers have varying degrees of water resistance.

Verify whether your tonneau cover has adequate water resistance features such as overlapping seams, weather seals, or integrated drainage systems. 

These features help prevent water from seeping into the truck bed and damaging any cargo or equipment.

Understanding your tonneau cover’s water resistance capabilities will allow you to assess its compatibility with the carwash environment.
