For tire cargo stains, the recommended cleaning method is?

The recommended cleaning method for tire cargo stains is power grind/paint. This approach is effective because tire marks can be deeply embedded in the container's surface and sometimes require a more aggressive method to completely remove the residue. The grinding or painting process allows for the effective elimination of these stains by removing the top layers of the affected surface, which may contain the deeper penetrated tire material.

Utilizing power grinding not only addresses the remaining stains but can also help restore the container to its original appearance, ensuring that it is suitable for future cargo. Furthermore, this method can be essential in instances where aesthetic concerns are paramount, as well as addressing any potential contaminants that may arise from the tire materials.

While other methods, such as hot high-pressure washing or spot cleaning, can be beneficial for various types of stains, they may not be sufficiently effective for the more stubborn tire stains that power grinding can remove.
