I bought a Waterman eyedropper at a flea market and the nib looks really gross and dirty. How can I clean it?
A stained gold nib can be removed if you know how to do so, but if not, you can also just polish it while it’s in the section. You won’t be able to polish all of it, obviously, but a good portion can be reached. Many people use jewelry polish cloths, which are easy to find and not too expensive.
