I'm going to get on my soap box now so bear with me.

As a cat owner I can testify that this actually has worked better than pet store solutions in our house:First mix vinegar and water 50/50 and soak the areaWhen almost dry soak the area with a mix of 1 cup hydrogen peroxide (3%) mixed with 1 teaspoon of dish soap.

Only two weeks into renting this apartment he had junk piled half way up the walls in every room loaded with boxes of diapers, soaps and shampoos and oven containers of food.

A campaign is comprised of a series of contact points, perhaps multi-media, ideally targeting these leads with specific USP's for the scenarios you are fishing for. 

We prepare a move-in gift package that includes cleaning supplies (degreaser, carpet spot cleaner, vinegar, baking soda, magic eraser, disinfectant wipes), cutting board, plunger, hand soap, dish soap, paper towels, and toilet paper, presented in a cleaning bucket and reusable shopping bag. ($30)  At move-in we also loan the tenant the use of drop cloth runners (to protect the flooring on move-in day), furniture moving blankets, furniture sliders, furniture lifting straps, a step stool, and a picture hanging tool kit (with small hammer and picture hooks). 

No wastes, soaps, etc were found on the surface but again it was raining a lot prior to inspection.No info on water wells.

On Halloween our cars were the only cars in the lot that did not get the windows soaped.

-advise cleaning the kitchen nightly with soap and water.

We nearly replaced our dishwasher due to the soap we had used for years no longer working effectively.

I like doing the a/c & d/w. say no to shower doors, tenants do not like them. they don't want to clean the tracks or deal with soap scum on the doors and they feel that they are unsanitary.
