In the summer it's less often because we don't get a ton of rain. I'll hit it with some Finish Line Dry once every week or so, and I don't need to clean it for most of the summer.
In the winter, I'm usually swapping chains once a week on the commuter. One on the bike, one soaking in mineral spirits.
