I used to think my dishwasher cleaned itself. After all, it runs with hot water and soap every day. Then I noticed a musty smell every time I opened it. My glasses started looking cloudy.

I realized my dishwasher was dirty, and I had no idea how to clean it. That is when I learned that dishwashers need regular cleaning too. Food bits, grease, and soap scum build up over time and make the machine work less well.

The good news is that cleaning a dishwasher is easy and cheap. You do not need fancy products. Vinegar, baking soda, and a little time are all you need. Here is the simple 3‑step method I use every few months.

Step 1: Clean the Filter and Drain

The filter catches food bits so they do not clog your machine. Over time, it gets full of gunk and starts to smell. Cleaning it is the most important step.

What you need:

• An old toothbrush
• Warm, soapy water

What to do:

1. Empty the dishwasher and remove the bottom rack.
2. Find the filter at the bottom of the dishwasher. Most machines have a twist‑off filter in the center. Check your manual if you are not sure.
3. Twist and lift the filter out.
4. Rinse it under warm running water to remove loose bits.
5. Scrub it with a toothbrush and warm, soapy water. Pay attention to the mesh and crevices.
6. Wipe the filter housing (the hole where the filter sits) with a damp cloth.
7. Put the filter back and twist it to lock it in place.

While you are there, check the drain area at the bottom. Remove any visible food scraps or debris.

🧼 My Personal Experience: The first time I cleaned my filter, I was disgusted. It was covered in a slimy grey film. I had no idea that much gunk was hiding in there. After I cleaned it, the musty smell was gone. Now I check the filter every month, and it takes less than five minutes.

Step 2: Unclog the Spray Arms

The spray arms have tiny holes that spray water onto your dishes. Food bits and hard water minerals can block these holes. When that happens, water does not spray properly, and your dishes do not get clean.

What you need:

• A toothpick or a small pin
• Warm water

What to do:

1. Remove the spray arms if you can. Most lower spray arms pull straight up. Upper arms may twist off or unscrew. Check your manual.
2. Rinse them under warm water.
3. Look at each tiny hole on the spray arms. If you see a blocked hole, gently poke it with a toothpick to clear it.
4. Rinse again and shake off excess water.
5. Put the spray arms back the way you found them.

🧼 My Personal Experience: I once had a spray arm where half the holes were blocked by tiny bits of eggshell and seeds. After I cleared them, the water pressure was much stronger, and my dishes came out noticeably cleaner.

Step 3: Run a Vinegar and Baking Soda Cycle

This is the deep clean for the inside of your dishwasher. Vinegar breaks down grease and soap scum. Baking soda removes odors.

What you need:

• 1 to 2 cups of white vinegar
• 1 cup of baking soda
• A dishwasher‑safe bowl or measuring cup

What to do:

1. Make sure the dishwasher is empty.
2. Pour 1 to 2 cups of white vinegar into a dishwasher‑safe bowl.
3. Place the bowl upright on the top rack of the dishwasher.
4. Run a hot water cycle. Use the hottest setting your machine has. Turn off the heat dry option if you can. Do not use detergent.
5. When the cycle finishes, open the door. Remove the bowl.
6. Sprinkle 1 cup of baking soda along the bottom of the dishwasher.
7. Run a short hot water cycle. Again, no detergent and no heat dry.
8. When the cycle finishes, open the door and let the dishwasher air dry.

⚠️ Important: Some dishwasher manuals advise against using vinegar because it is acidic and could damage parts over time. I use this method every 3‑4 months, and it has been fine for my machine. But check your manual first to be safe.

Extra Tips to Keep Your Dishwasher Clean

Here are a few habits that help keep your dishwasher fresh between deep cleans.

• Scrape off large food bits before loading dishes. Do not rinse them completely—detergent works better with some residue.
• Leave the door slightly open after each cycle. This lets air circulate and prevents mold and smells.
• Clean the door seals once a month. Wipe the rubber gasket around the door with a damp cloth and mild detergent.
• Use rinse aid to prevent hard water spots on your glasses.

How Often Should You Clean Your Dishwasher?

• Filter: Every 2‑4 weeks
• Spray arms: Every 2‑3 months, or when you notice poor cleaning
• Vinegar and baking soda deep clean: Every 1‑3 months

The Bottom Line

Cleaning your dishwasher is not hard. You do not need expensive products. Just vinegar, baking soda, a toothbrush, and a little time. Clean the filter and spray arms first. Then run a vinegar cycle and a baking soda cycle. Your dishwasher will smell fresh, work better, and your dishes will come out sparkling.

I clean my dishwasher every three months now. It takes about 30 minutes total, and most of that is just waiting for the cycles to run. My machine is five years old and still works like new. Try these steps this weekend. Your dishwasher will thank you.
