Hiya guys.
I am sorry but I am on vacation this weekend og do not have my notes and spreedsheets with me. I will be happy to get you some hints but I am wont be back before late monday.
From you info text regarding cleaning the room. It is not needed for progression and will auto unlock at a certain point. You can use the shower in your room at 6 with 'shower' commands.
Again sorry to not be of more help right now.
