They say you get more flies with honey than with vinegar, so I haven't actually done that yet, and I'm not sure it would make it any better (and quite possibly worse).I know some of you use the "carrot on a stick" method by offering some upgrade or service with the rent increase as a way to increase tenant buy-in and compliance.  

Weak link in the plumbing... it's probably not the actual toilet. 1. put 1/4 cup baking soda in toilet bowls and sinks 2. then a cup of vinegar, it will bubble, let it sit an hourflush, rinse sinks with two cups more or less of boiling waterThis should cut out the bacteria high up in the drains for a couple weeks.I would give the tenant a big box of baking soda and walmart gallon bottle of vinegar and notsend a plumber.

Scrubbing really nasty floor grout with white vinegar and a scrub brush removed the accumulation of oil and dirt that I feared would not come off.

One of the best drain opening/maintenance techniques I've used in multiple old homes is by pouring 1/2 a gallon of white vinegar down the drain, letting it sit for a few hours and then run warm water through the pipes as a rinse.  

My dad used to say "Try honey first to get what you want before bringing out the vinegar". 

Wash the kitchen surfaces with white vinegar.

If you are try to kill mold on concrete in a basement, use a sprayer and vinegar with 25% water.

As the saying goes, "You catch more flies with honey than you do with vinegar".
