I have a couple of backs that need a good cleaning. I notice that the grid lines drawn on the "ground" side of the glass are very fragile. If I use windex and a paper towel, for example, I end up completely removing the lines. I never realized that these were so delicate?? What is the proper way to clean ground glass like this?? Almost looks like wax on an original Deardorff back. Is that what it is?
Thanks
