I have a clock that has a pretty corroded plug. The clock plug is not polarized. You can plug it in any which way.
I also have a spare electric cord that is wired with a polarized plug.
I'd like to use the spare cord to rewire the clock.
I can see how wiring a device that expects a polarized plug with a non-polarized plug would be a Bad Idea. But I'm pretty sure putting a polarized plug on a device that does not expect it won't hurt.
But I want to double check that. Am I missing something here?

You're absolutely right.
Since the original plug is non-polarized, the clock doesn't care which wire is live and which is neutral. With the polarized plug, live is always going to be on one wire, and since the clock doesn't care which one, neither should you.
The only thing to worry about is that the new wire is the same gauge or thicker so that you can be sure that it will safely carry the current that the clock requires.
