Glue clean-up

It seems that one topic that is never discussed in woodworking books or articles is the best way to clean up glue squeeze-out from glue-ups (especially inside corners). Is it better to clean the glue out wet with a wet rag (and risk staining), wait till it skins over, or scraping after it has dried. Or is the best approach to tape the inside corners. I have tried all these approaches and would like some input on the best way that others have found.
