@Wayne Snell, congrats on your 1 year anniversary from the rate race too!  

If you put a lamp on the floor and put about five or six pie tins around it with water in it then squirt some dish soap in it and turn the light on.

Makes total sense for too much soap and water residue is not good for the carpet and could attract dirt in the future. 

I raise rents every year, on their anniversary. 

I've arranged for my PM to take a smaller percentage since I'm still the one handling bookings, doing small maintenance and keeping up with supply inventory.A better example is the service I get from my housekeeper at my new rental in Tennessee: she does the post-stay walk-through, cleans, and provides or maintains the inventory of supplies (she provides quite a bit: trash bags, toilet paper, basic toiletries, dishwashing soap, hand soap; the things I provide, she'll let me know when supplies are low, and I'll have new items shipped to her house).  

If it's a honeymoon or an anniversary the cleaners put two towels in the shape of swans kissing on the bed to look like a heart or some cheesy equivalent. 

@Tawny Bloom - the pipe clogging issue is a result of soap and oil chemically mixing and sticking to your pipes.  

(Dragging out soap box)Peter,I'm sure these are fantastic resources and I always encourage my clients to gain as much knowledge as they can, but the biggest issue I see is NOT getting the correct answer to your question.  

Bath towels would go, along with soap, toilet paper, paper towels, laundry detergent, etc. 

Actually just had a couple people come up on their anniversary so they will be getting their ~$1.50 check in time for Christmas!
