Mick,Stick with Prochem, you can't get better for things like pre-sprays and rinse agents. Craftex Rust Remover is brill and so are some of the deodourising products but on the few occassions I have strayed from the Prochem range to try a cheaper option I end up going back to what is clearly the best.Simon
