How to clean cloudy glasses?

I have a question regarding cloudy goblets. My goblets are pressed glass that have been in the family for quite sometime. I am not sure if they are Indiana Glass such Hocking or not. Anyhow, the last few years they have become increasingly cloudy to the point that I don’t want to use them as they are. I have tried to clean them with vinegar, baking soda, Clorox and ammonia.  Each time to no avail. Please tell me if you have any other ideas. I would appreciate it so much!
Thanking you in advance.
