Hi
Yes a chemical bath is a de-ironiser. I use it after washing, but re wash after using also before rinse off.
By standards C1 is an expensive product. Thats like saying crystal rock is cheap because it costs £795.00 a tub, but you could apply around 45 coats. If you broke down whats exactly used im sure all things are cheap. P-ZERO Tyes cost X amount but I get x amount of miles. So in the breakdown there dirt cheap too
But life's not quite like that is it.
