Check out how to clean out dishwasher yuckiness and keep it running efficiently. These steps work for most dishwashers, but sometimes you will find a discrepancy, so it's a good idea to review your owner’s manual before getting started.

4. Clean the Dishwasher’s Spray Arm

Wipe down the spray arm with a damp cloth. Use a toothpick to unclog any debris or bits of food from the holes in the spinner arm. And if you want to know how to clean out dishwasher spray arms thoroughly, remove them from the dishwasher. It’s a simple procedure that doesn’t require tools—just check your owner’s manual for instructions.

5. Realign Dishwasher Rack

Make sure the wheels are aligned. If they're off-track, the rack may block the spray arm from rotating and result in a poor cleaning. Also make sure to load dishes properly so they don’t block the spray arm either.
