The Art of the Deep Clean: Mastering the Traditional Hand Wash for Lorries, Buses, and Heavy-Duty Fleets

The chemicals used in a traditional hand wash for heavy vehicles are significantly more potent than those found in a home garage. Traffic film removers (TFR) are essential for breaking down the greasy "road film" that accumulates over thousands of miles of highway travel. These cleaners are often applied as a thick foam that clings to the vertical surfaces of a coach or trailer, giving the active ingredients time to emulsify the oils and soot from diesel exhausts. Watching a professional team apply this foam is like seeing a giant sculpture being encased in white, a visual indicator that the deep-cleaning process is underway.
