Before you dismantle the entire appliance, try the simplest trick in the book: white vinegar. Place a cup filled with white vinegar on the top rack of an empty dishwasher. Run a hot water cycle. That’s it. The acid in the vinegar will dissolve the mineral deposits inside the machine and give your next load a fighting chance. (Side note: your kitchen will smell like a salad dressing factory, but that’s a small price to pay for shiny glasses.)
If the vinegar trick fails, grab some citric acid powder. You can find it in the canning aisle or on the internet. Sprinkle a couple of tablespoons into the detergent dispenser and run a hot cycle. It’s like a detox spa for your dishwasher. Results are usually immediate—your dishes will emerge looking like they just got a professional polish.
And for crying out loud, clean your dishwasher’s filter. If you haven’t done that in the last three months, I’m judging you—in a loving way. A clogged filter recirculates gunk right back onto your plates. It takes two seconds: pop it out, rinse it under hot water, pop it back in. You’re welcome.
