Run a Citric Acid Cycle
Pour half a cup of citric acid crystals into the soap cup. Run the machine empty on the hottest, longest cycle. Citric acid breaks down scale on the spray arms and walls. Run a normal cycle with detergent after to rinse.

White Film Inside Your Dishwasher Is Not Soap
Tucson homeowners often blame their detergent when dishes come out cloudy. The real cause is mineral scale from hard water. It coats the spray arms, filter, walls, and heating element. Once scale builds up, it flakes off and lands on dishes. A citric acid cycle dissolves it at the source. Alex's deep clean add-on includes the dishwasher interior.
Clean the Filter
Remove the lower rack and twist out the filter. Rinse it under warm water. Use a soft brush to clear food stuck in the mesh. Put it back before running the machine.
Descale the Spray Arms
Clogged spray holes leave dishes dirty. Remove the spray arms and soak them in warm citric acid water for 20 minutes. Use a toothpick to clear any blocked holes. Rinse and reattach.
Monthly Dishwasher Cleaning Checklist
- Clean the filter every two to four weeks.
- Run a citric acid cycle once a month in Tucson's hard water.
- Check spray arm holes and clear any blockages.
- Wipe the door gasket and door edges with a damp cloth.
- Clean the soap cup to remove residue buildup.
Why Citric Acid Works Better Than Vinegar Here
Vinegar is a mild acid. It works on light mineral film. Tucson's water runs 300 to 400 parts per million. That leaves heavy scale vinegar cannot fully cut. Citric acid is stronger and dissolves calcium more fully. It is food-safe and leaves no odor. Buy food-grade citric acid powder from the bulk or canning aisle. Run a follow-up cycle with detergent to flush the machine.
The filter is the part most homeowners miss. A clogged filter recirculates food bits through the wash cycle. That is what causes the gritty feel on dishes. Clean the filter every two to four weeks. If you run the machine daily, check it every two weeks. Alex's deep clean wipes the dishwasher exterior and door seal as part of the kitchen clean.
