Testimonials

Andrew

Koch Chemie Green Star

As a regular user of the excellent Bilt Hamber Surfex hd, I purchased Green Star on the strength of numerous reviews, and although having only used it twice, have not been disappointed. Used at a dilute ratio of 1:10, it cleaned the underside of my bonnet, the more plasticy parts of my engine, door sills and hinges with ease. Recommended.
