My pet peeve is when the kids or missus put a barely dirty dish in the sink or dishwasher.
Like a knife and cutting board that was used for a cucumber.
Or the apple slicer, a bowl that was just used to munch on some dry cereal, a spoon used for stirring a drink, a pot used for boiling noodles or vegetables, a coffee cup, a glass of water.
And a million other things that all they need is a quick rinse and wipe right after use, not a full on hot water bubble bath or 5 hours in the dishwasher.
There’s also many times a frying pan or cookie sheet only needs a quick wipe with a paper towel too. A little sheen from oils/butter is fine to leave on cookware.
Most people could probably cut their dish “washing” in half because they’re not actually dirty.
