I found this in the local Home Hardware store.
I've given up trying to find the MAAS metal polish the yanks are always going on about. I thought I'd give this stuff a go. Works well, as you can see. The right of the blade is before, the left is after about two minutes of buffing.
It is made in Solingen too, which should be a hint.
