Dear sir, Thank you very much forthis formulation. I would like to try it, but I can find the sulphonic acid powder. Can I use the sulphonic acid and wait for it to dry out?
It's more suitable for clothes, and other few domestic uses. For a car wash shampoo, consider this formulation : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ycWV8Ja6XZI.html
