I agree with Jeana. Sadly you can put up all the signs you can, and make all the announcements you can, and post all the ushers you can, and food. and drinks (other than water) still make their way into the house. But, imagine the situation if you didn't make these attempts at all - your house would look like a movie theatre.
I also agree that you should charge them extra for cleaning, and be sure that that's on the rental agreement. And as Jeana says, be sure it's on a separate line, and possibly Bolded, possibly Italicized, possibly Underlined....
Do you have a separate House Management written policy that you give to outside events and make them sign? Do you hold a production meeting with each outside event (each time, if they are repeats)? Both of those are an essential part of your theatre management. (Not that they will help 100% either(!), but it will improve things.)
