As a matter of fact, I did pour in some PBW & used a small, soft cloth to wipe it down after spraying the crud ring out. Then rinse & store. Works fine so far.
I let mine soak in warm PBW for 30 min, then drain, rinse, and fill with Starsan solution so its ready for the next brewday.
As in you leave the starsan solution in there up until you are about to brew? There won't be any ill effects from doing that?
