Especially if you use a small amount of detergent in the pre-wash compartment. Most people (at least in Europe) just use a single tablet in the main wash section. I've seen a massive improvement by putting a teaspoon amount of detergent in with the pre-wash. The ever-wonderful Technology Connections sent me down this path.[1]

Without detergent in the pre-wash compartment, only water is used to pre-soak the dishes.

Then there's the way my mother-in-law uses the dishwasher: turn on the faucet as high as it goes, then rinse each dish so much it could just go straight in the rack, then load the dishwasher, then FINALLY turn the water back off.
