A dishwasher that’s quietly losing efficiency doesn’t always announce it — dishes just start coming out a little less sparkling, glasses stay foggy, and the machine seems to run longer than it used to. The usual culprit is buildup: grease, soap scum, and mineral deposits collecting around the filter and spray arms, forcing the appliance to work harder and burn more electricity for the same result.
Why cleanliness affects your bill
When the inside of a dishwasher is free of gunk, water heats and sprays the way it’s designed to, which means shorter cycles and less energy per load. Skipping maintenance doesn’t just mean dingier dishes — it quietly nudges your power bill up over time.
Baking soda does the heavy lifting
Baking soda is mildly abrasive, which lets it scrub away residue without harming your machine’s interior, and it neutralizes odors as it works. Paired with white vinegar, it helps dissolve the grease and limescale that build up in corners a regular cycle can’t reach.
How to do it
- Empty the dishwasher completely.
- Wipe out any food debris sitting at the bottom.
- Sprinkle one tablespoon of baking soda across the bottom of the machine.
- Optionally, set a cup of white vinegar in a dishwasher-safe container on the top rack.
- Run a full hot cycle with no detergent added.
- Once it’s done, wipe down the interior, seals, and door edges with a soft cloth.
Doing this once or twice a month keeps grease and mineral buildup from taking hold, so the heating element and spray jets don’t have to fight through gunk to get dishes clean. The upside shows up twice — in the sparkle of your dishes and in a slightly lighter energy bill.
