ABSTRACT:
A concentrate and a ready-to-use or diluted formulation for an aqueous vehicle cleaner can remove a wide range of different types of traffic film using either low pressure application, hand pressure application, water jet spray apparatus, clean-in-place systems or other manual or mechanical washing systems. The compositions may comprise, for example, one or more solutions that each or collectively contain or comprises:a) at least one anionic surfactant;b) at least one poly[oxyalkylene] ammonium cationic surfactant; andc) an alkaline agent.Optional additional ingredients may comprise at least one polycarboxylic acid chelating agent (preferably an aminocarboxylic acid chelating agent), at least one non-ionic or amphoteric surfactant, at least one hydrotrope, inorganic and/or organic acids and at least one silicate. The alkaline agent may provide a pH (when the finished product is diluted to 0.5 to 5% by weight in water) will be between about 9 to 13. The concentrate may be provided as a one-part or two part solution. Certain formulations have been found to be shelf stable as one-part concentrate or ready-to-use solutions, even with significantly different properties amongst the components. The compositions of the invention are also used in cleaning processes for surfaces, especially vehicle surfaces in car wash systems. The compositions are used in such processes where there are single or multiple liquid application steps.
