I do not think that blowing the chain out will remove all of the water from the tiny crevices. Waiting for it to dry has even poorer results; think of water trapped between two panes of glass, it takes pretty much forever for it to totally disappear. I put the chain on a pan into a 250F oven for a half hour which vaporizes the water and ensures that it is all removed. I use quick links and remove the chain for cleaning.
