What must be done with tape that remains on walls and is unacceptable for cargo shipment?

When tape remains on the walls of a shipping container and is deemed unacceptable for cargo shipment, the proper action is to scrape or spot clean the area. This method effectively removes the adhesive residue and any associated contaminants that could interfere with the cargo. Scraping or spot cleaning is a targeted approach that ensures the surface is clean without damaging the container itself. It allows for specific areas to be addressed rather than subjecting the entire container to more abrasive or intensive cleaning methods.

This approach is crucial because leaving tape or residue can lead to potential damage to the cargo being transported, as adhesives can attract dust, dirt, or moisture, potentially causing issues such as mold or contamination. By ensuring a clean surface, the integrity of both the container and its contents is maintained.
