I'm late to the Maas bandwagon, having only used it for a few months but I'm a total convert. Loving silver as I do, I have quite a collection and polishing it every few weeks with conventional polish became quite a chore. With Maas, I find that I need polish much less often which is welcome news. The clincher for me, though, is that several of the older pieces never really responded to my old polish and I thought they were beyond repair. With Maas and a little elbow grease, they positively sparkle.
