You know that little compartment labeled “rinse aid” that you’ve been ignoring for three years? That’s not a suggestion; it’s a cry for help. Rinse aid contains surfactants that break the surface tension of water, causing it to sheet off your dishes instead of beading up and baking on those minerals.
Without it, your dishwasher is like a car without windshield wipers in a mudstorm. Rinse aid is cheap, people! Pour some in and watch your glasses go from “foggy” to “crystal ball ready.”
