thank you sir,i am not a detailer at all,just seeking knowledge till yet.
About water i used about 200ml mixed with about 40 ml of PS,then apllied with air,then given a diesel air sprey,took turtle engine cleaner and washed the components using brushes,but at the end i had to blow a little water too(away from electricla components),to complete the process and then rubber/plastic conditioner over them.Dont you think PS more like an acid?i think frequent use of PS is harmful to the rubber pipes.
Water did bother me like head lamps relay got fried(even i coverd them with plastic bags) and i replaced it afterwards.
