Soy based cleaner for Graffiti

[Pressure works]

I was looking at graffiti removal of paint from brick walls. I was asked to check into Soy based cleaners by the client. I have done a little research on the web and found a couple of products and was wondering if anyone had any experiance with this type of cleaner let me know. One of the products is Soysolv the other is Archer Graffiti remover. Have you heard of them? They are supposed to be Echo sound.
