How can I get rid of glass smears?

The internal glass on my car always has a thin, grimy film on it. I have used soapy water followed by commercial glass cleaner, but can't get rid of it. I have also tried my own water/vinegar mix, but no matter which method or product I use I can never get them clean. Can you tell me how to get clean, smear free internal glass?

Use a powder based screen cleaner such as MER.
