My parents had a dishwasher but always said it "didn't get the dishes clean" and used it as a drying rack instead. I bought a house where the dishwasher was incorrectly installed causing odors to come through the sink. That led me down a rabbit hole of proper dishwasher installation, maintenance, loading and using rinse aid. MY GOD! My parents were wasting their lives! My dishwasher cleans and dries two sinks worth with three minutes of effort!
