Unless you got something liquid in there, I wouldn't be worrying about cleaning your pot already. Sometimes it does more harm than good. I only clean a potentiometer when there is a degradation in sound. It is unlikely that any lint has made its way into your E12 pot already.
edit: But if you are already hearing that degradation, I would see about getting a replacement unit from the seller.
