How to Deep Clean Your Dishwasher (Yes, It’s Dirtier Than You Think)

Let’s be real cleaning your dishwasher feels a little ironic. After all, it’s a machine built to clean. But over time, food particles, grease, and soap scum build up, leaving your dishwasher grimier than you’d expect. If your dishes are coming out cloudy or smelling less than fresh, your dishwasher may be in need of a deep clean.

Fortunately, giving it a little TLC is easier than you think. Here’s how to clean your dishwasher, how often to do it, and tips to keep it fresh between scrubs.

Step-by-Step: How to Clean Your Dishwasher

1. Clean the Drain

Your dishwasher’s drain can accumulate food debris that affects performance. Here’s how to clear it:

• Remove the bottom rack and locate the drain at the base of the dishwasher.

• Use a paper towel or sponge to remove any visible food particles.

• Try to make this a habit after each wash to prevent buildup.

2. Wash the Filter

Most dishwashers have a cylindrical filter and a metal coarse filter.

• Twist the filter counterclockwise to remove it, along with any metal plate if present.

• Wash both pieces in hot, soapy water using a gentle brush.

• Check the sump (the hole where the filter goes) and clear any debris.

• Reinsert the filters once they’re clean.

3. Run a Vinegar Cycle

White vinegar helps cut through grease and odors:

• Fill a dishwasher-safe cup with white vinegar and place it on the top rack.

• Run a normal wash cycle using the hottest water setting.

4. Follow Up with Baking Soda

To deodorize and brighten the interior:

• Sprinkle about 1 cup of baking soda on the bottom of the dishwasher.

• Run a short, hot water cycle. That’s it!

5. Wipe the Rubber Seal

Gunk can collect around the rubber gasket of your dishwasher door.

• Use a damp cloth and soapy water to wipe the seal and surrounding edges.

• Don’t forget the crevices they can hide a surprising amount of grime.

6. Shine the Exterior

• For standard finishes, a soapy cloth will do.

• For stainless steel, opt for a specialized cleaner to keep fingerprints and streaks away.

Why Bother Cleaning Your Dishwasher?

Dishwashers may clean dishes, but that doesn’t mean they clean themselves. Over time, food particles clog drains and spray arms, reducing water pressure and cleaning power. That film you’re seeing on your glasses? It’s probably a sign your dishwasher is overdue for a refresh.

Regular cleaning:

• Improves washing performance

• Eliminates odors

• Helps extend the life of the appliance

How Often Should You Clean It?

Experts recommend giving your dishwasher a deep clean about once a month, especially if you use it daily. If you're a less frequent user, you may be able to space out cleanings every 6 to 8 weeks.

Tips to Keep It Cleaner, Longer

• Scrape, don’t rinse: Remove large food bits before loading your dishes, but don’t over-rinse modern detergents are designed to cling to grime.

• Run it full: Save energy and water by only running full loads.

• Leave the door ajar: After a cycle, open the door slightly to let moisture escape and prevent mold or mildew.

• Inspect the filter: Check it weekly for buildup if you use the dishwasher often.

A monthly routine that includes cleaning the filter, drain, and interior with vinegar and baking soda can help your appliance run more efficiently and leave your dishes looking spotless. A little maintenance goes a long way in keeping your kitchen running smoothly.
