I don't bother stressing. I make sure it's tidy and that's it. If they look at anything other than general upkeep of the house or for damage then they are over the top real estates. I once had an agent tell me I had to remove dust from the ceiling fans... She was am idiot, and I didn't clean this fans for another 6 months till we moved out lol.
If they comment on cleanliness tell them to get stuffed.
