I work with the assumption,,,if it is working great,,,don't mess with it...I use to change out my attys during the day to give them a break and to drain any excess juice out of them,,,stop the flooding problem,,,but, the second atty I put use for some reason or another never worked as good as the one that I was already using...So,,,now I use the same atty everyday, only take it out and sit overnight on end with a paper towel...Once I can tell it isn't working as good, then it is time for a fast cleaning and use another one for the next few days or week...Just the way I do it....Enjoy...
