Abstract
Retrofit systems are provided to convert existing automated vehicle washing systems from using conventional car wash chemicals to highly concentrated chemicals. The retrofit systems enable the concentrated chemicals to be pre-diluted before they are mixed with water from the main water supply. The two systems provided enable the operators of existing car washes to convert from conventional chemicals to highly concentrated chemicals without purchasing an excessive amount of new equipment or carrying out extensive modifications of existing equipment. A novel feature of one embodiment of the present invention includes the use of pre-dilution block for mixing highly concentrated chemical with pre-dilution water prior to the introduction of the mixture to the spray arch where it is diluted again with water from the main water supply. A second embodiment includes the pre-dilution of concentrated chemical twice before it is introduced to the spray arch where it is again diluted with water from the main water supply.
