Before and After Polishing

One of the annoying things with buying a used radio is the case may not be in very good condition. The worse is the display cover "glass", really just plastic. I found a good way to clean some of them up by using tooth paste and a damp cloth/paper towel to polish the screen. It works but takes a lot of time and effort. If done well the results are very good. In the photo is an example of a TK-370 radio with the cover glass showing a very noticeable scratch and cloudy complexion. After the polishing it looks almost new.
