Okay, so I've found the advice provided here about working the pots back and forth 20-30 times works well.
And so that's what I do.
But the question I have is this: is it normal to have to keep doing it every so often? I ask because I've gone through the process several times, and it seems the issue comes back...and then I resolve it...and then next time I go to play, I keep repeating the process.
