There's no such thing as too long. That said, however, the benefits stop
once all the excess bitartrate has precipitated.

If it's in a glass carboy you want to make sure that it doesn't get cold
enough to freeze the wine. For table wines of typical alcohol concentration
you can go as low as about 26°F. That said, I'd recommend that you play it
safe and go no lower than 30°F. That's cold enough to do the job.
