Never overload your dishwasher
Nobody wants to load and unload two rounds of dishes in the dishwasher when they could just shove all of their dirty plates and silverware into one. However, cramming everything into one load will result in dirtier dishes in the long run. That's according to a 2015 study published in the Chemical Engineering Journal, which found that overloaded dishwashers resulted in less effective cleanings. Better to save yourself the frustration of unloading unclean dishes and do things right the first time.
