Im gonna try Odorxit and put a plastic sheet over it after I soak it.

Guests staying more than 30 days are likely going to cook at least some of their meals, and nothing ruins a stay faster than opening up the cupboard to discover worn, dingy, and damaged cookware.Best practice: Buy a new, inexpensive yet COMPLETE set of cookware, containing at least a frying pan, a covered skillet and two sauce pans.

I prefer thicker, hard plastic tongue & grooves to paper/cardboard/rubber as they seem to stay locked together better over time. 

Just make sure there is enough space for absorption that the next neighbor down the hill is impacted.The house probably has an original foundation drain,  if an older home probably concrete tiles,  if newer some kind of plastic.   

Quote from @Stephen Fry: Hello, I am new to rental real estate and I look forward to learning from people who have experience. 

It also helps that I inform my guests that a starter supply of paper and plastic items are provided and ask them to replace any items they have used up. ( This may not be popular with others but I have never had a complaint and for the most part,  items used are replaced)

.: @Ashley Bitner I've had mixed experiences in that even with a cleaner I trust, even with providing checklists, things get dropped inevitably because no one is going to catch those details as well as you (e.g. the nonstick frying pan that needs to be replaced, missing extra kitchen towels or remote, propane refills...).

Looks like they will eventually move to cap us small fry NY owners. 

I kocked out the plastic plug with a screwdriver and am waiting on  a cycle to complete to make sure that was the only problem.I called the new to me handyman and he said there is a knockout plug?

I don’t know of any contractors who would do more than hang plastic sheeting over open entrances, maybe on a good day they might block a heating vent if you’re lucky.after I’ve had all the demo and drywall done, I have a cleaning lady I know come in to clean every surface, ceiling to floor.
