Just a tangent - I read once and then discussed with a microbiologist colleague - the dish towel is the dirtiest part of doing dishes. So letting dishes air dry in a dishwasher is sanitary. Getting a dish-rack (obviously setting it up so it drains into the sink) and just putting clean wet dishes into it is sanitary. Drying a bunch of dishes with a dish towel is less sanitary, and takes more time. So for those with few dishes (one or two people, or meals with few dishes) just washing and leaving them to dry in the dish-rack is fast and efficient.
Comment from my Scouter days - the biggest cause of upset tummies in campers is eating off poorly rinsed dishes (it's more work to heat more rinse water over the cook fire, so people tend to let the rinse water get too soapy). So hot water and a bit of dish detergent for cleaning, but definitely a good rinse in hot water to get the detergent off. I did it in a tiny apartment a few years ago, you can wash dishes quite easily in a one-basin kitchen sink. And the dollar store has lots of inexpensive dish basins if needed. I actually washed the dishes in a basin, rinsed in the sink, and drained in the dish-rack.
