This was actually one of our first major disagreements as a couple, years and years ago.
If a pot/pan/bowl was hard to clean, I would often fill it up with water and then come back later and scrub it. Mrs. Bee preferred not to leave water like that, as it could lead to bacterial growth. (More recently, I just started doing them quickly so that soaking isn't really necessary).
Is it safe to soak dishes in water for a few hours/overnight? Or does it put the dishes at too much risk of bacterial growth,,,
