Keeping a dishwasher clean helps maintain optimal performance and extends the appliance’s life. This guide outlines simple, effective steps to remove buildup, freshen the interior, and keep spray arms and filters working properly. By following a routine cleaning plan, homeowners can prevent odors and improve washing results.
Quick Answer
Do a quick clean once a month: run an empty cycle with a dishwasher-safe cleaner or a cup of white vinegar on the top rack, then scrub the door seal and interior with a brush. For stubborn debris, use the included tools to reach deep into filters, spray arms, and crevices.
What You’ll Need
The following tools and materials will help you clean your dishwasher efficiently. Most items are common household or small specialty tools.
- Dishwasher cleaning brush with long handle
- Dishwasher filter cleaning brush
- Dishwasher spray arm cleaning tool
- Dishwasher interior scrub brush nylon bristles
- Dishwasher safe cleaning sponge set
Before You Start
Prepare the area with the dishwasher opened and dry towels nearby. Unplug the appliance or switch it off at the breaker before servicing to ensure safety. Clear the bottom and remove racks to access the interior, filters, and spray arms. Time estimate: about 45–60 minutes for a thorough cleaning.
Note that hard water minerals can build up faster in some regions. If you notice white mineral deposits, choose a rust- and mineral-removing cleaner suitable for dishwashers. Avoid abrasive tools that could scratch enamel surfaces.
Step-By-Step: How To Clean A Dishwasher
- Empty the dishwasher and remove racks to expose the tub, filter, and spray arms.
- Wipe down the door seal and outer surfaces with a damp sponge to remove residue and grime.
- Inspect and clean the filter: remove the filter assembly, using the dishwasher filter cleaning brush to loosen trapped debris, then rinse under running water.
- Clean the spray arms: use the dishwasher spray arm cleaning tool to clear any clogs in the small holes; gently poke out obstructions without bending or breaking the arms.
- Scrub the interior: with a dishwasher interior scrub brush nylon bristles, reach corners, corners near the door, and bottom recessed areas to remove grease and mineral buildup.
- Run a cleaning cycle: place a dishwasher-safe cleaning tablet or a cup of white vinegar on the top rack and run a full hot cycle. Do not add detergent for this cycle.
- Wipe the interior after the cycle to remove loosened residues and dry the tub with a towel to prevent moisture buildup.
- Check gaskets and seals: wipe with a damp cloth, then dry thoroughly; remove any hair or lint caught around the seal.
- Reassemble the racks and run a brief rinse cycle with cold water to ensure everything is back in place and balanced.
- Schedule regular maintenance: plan a monthly full interior clean and a quarterly deep clean for optimal performance.
- For persistent odors, repeat the cleaning steps, focusing on the filter area and spray arms, and consider a mineral-removing cleanser if deposits persist.
