When spillage on the exterior attacks cargo paint, what cleaning method should be utilized?

When addressing spillage on the exterior that has begun to attack cargo paint, the appropriate cleaning method is blast/paint. This method involves using abrasive materials to remove contaminants from the surface while also preparing the area for new paint application.

Blast/paint is particularly effective for cleaning because it not only removes the spillage but also helps to strip away any deteriorated paint and surface contaminants that could lead to further damage. After cleaning, it allows for a consistent surface onto which a protective paint can be applied, ensuring the integrity of the cargo and container is maintained.

Other methods, like spot cleaning, may only address visible stains and not adequately prepare the surface for repaints, while power washing, though effective for surface cleaning, may not address paint adhesion issues resulting from the spillage. Scraping the area could also damage the paint further and may not effectively remove all the spillage residues. Therefore, blast/paint is the most comprehensive method for this scenario.
