How far do you go with trying to get rid of pitting and stains etc. Do you just have to accept that the etching will not be saved at all. As you can see in the photo, I have polished it up as much as I could using the dremel.
What grade wet & dry do I start with? Sorry about the photo, I will have to improve my technique :) The other one I took was way out of focus. But if you look hard you can see the etching or part of it.
