looking for some help please,been trying for hours on end to get rust marks out of 2 very nice razors...without much success. Grey marks on one and small black marks on another with some rust on handle edging. Tried numerous stainless steel removal/polishing pastes etc,and I know everywhere I read suggests MAAS but it is not available in UK. Tried autosol,wd40 baking soda plus others including sliver pads,brasso etc Even tried soaking in hot water with a little wash liquid. This was a disaster as the blade turned black in places (anyone know why) Have tried dremmel with polishing pads.

Now getting frustrated...any help appreciated...Grey patch ? and small black marks will not remove.

Thanks in advance
