I don't have roommates. I use doggie poop bags to pick up any waste.
The big water bowls get dumped in the toilet, than washed in the sink.
I don't have dishes in the sink when I do it.
I use Vinegar to clean the bowls. Bleach on sinks and countertops.

Vinegar can be used as a safer bleach alternative for some applications, like cleaning. It is also biodegradable. However, vinegar is not a registered disinfectant and does not kill dangerous bacteria like staphylococcus.

Bleach is a strong and effective disinfectant. Its active ingredient, sodium hypochlorite, denatures protein in micro-organisms and is therefore effective in killing bacteria, fungus and viruses. Household bleach works quickly and is widely available at a low cost. Diluted household bleach is thus recommended for the disinfection of facilities.
