I understand your in California and we might be in the same district, if so explain the situation to her... She'll understand! If we're not I'm sorry because my dm does let me with an exclamation...
I would tell her that you are not working off the clock and that you have had customer complaints about spots on blankets and drapes so you are trying to prevent customer complaints and refunds. Then email your regional about it. Or call them. You will get then.
