Lately I have been hearing a lot about Amazing roll off, and its powerful cleaning action. I have heard it is a safe but powerful cleaner. I have seen that some people sware by it and they use it exclusively. I have also seen others that think it is just good, but nothing amazing. Also it says in the product summary that it leaves a wax like coating, does any one have any comments on this? how long does it last? Also does anyone know what PH ARO(amazing roll off) has? Does any one know how it compares to 303 cleaner? I would like to hear from people that have used ARO(amazing roll off) . I plan on buying a gallon with my next order.
