A method of producing a vehicle wash detergent/foam for cleaning cars, trucks and other vehicles using commercial vehicle washing equipment, which comprises the step of producing a vehicle wash detergent/foam concentrate solution comprising water as the suspending solvent; dodecyl benzene sulfonic acid as a detergent/foam agent; monoethanolamine, or diethanolamine, or triethanolamine as modifying substance to adjust the pH of the solution just to the base side of 7.0 and simultaneously form the amine salt of the dodecyl benzene sulfonic acid; either a 1:1 cocoamide DEA or a 2:1 cocoamide DEA as a detergent/foam agent; either sodium lauryl sulfate or an alpha olefin sulfonate as a detergent/foam agent; coco-dimethylamidopropyl betaine as a foam agent; propylene glycol as a solvent; either a 9-molar ethoxylated secondary alcohol or a 9-molar ethoxylated nonyl phenol as a surfactant; and monoethanolamine, or diethanolamine, or triethanolamine as an oil solubilizing agent. A vehicle wash detergent/foam solution is produced from the concentrate solution by introducing the detergent/foam concentrate solution to a stream of water through spray nozzles associated with the vehicle washing equipment.
