I am doing some temporary work for a few months and the company is paying for my housing in a nearby hotel. The room comes with typical housekeeping service to clean the sheets, bathroom, etc. I have been noticing that the walls of the shower are starting to turn pink, and when housekeeping comes through they have not been cleaning the walls.
I could clean them myself, as the houskeeping is certainly a great perk, but there are no cleaning materials in the room and I don't really want to go buy some only to throw it away half-used in a few weeks.
How can I ask for the shower to be more thoroughly cleaned without getting the housekeeper in trouble or offending them? Service workers do not have very easy lives, and this person will also be in my room a few times a week for another two months. I have considered leaving a note on my table.
Additional details: this is in the United States and many of the housekeepers don't speak much English. I usually get the room cleaned 2x per week. I have been leaving a tip of $5 USD per week.
