While the idea of cleaning your dishwasher may seem redundant, it’s actually a useful procedure that can keep your dishwasher working effectively! One of the main issues with dishwashers is that over time, food residue, grease, and soap scum can form stubborn deposits. This grimy buildup can make your dishwasher look dirty, smell bad, and even prevent it from cleaning your dishes properly.
Grimy dishwasher buildup can also prevent your dishwasher from draining correctly. This particular issue was the inspiration that lead me to find a method for cleaning my dishwasher in the first place! I had opened my dishwasher to unload the clean dishes, only to discover a bunch of standing water at the bottom.

But after a bit of research and experimentation, I discovered a highly effective method for cleaning a dishwasher, and that’s what I’ll be sharing with you in today’s post! I’ll start by quickly explaining how this method works, and then I’ll explain the simple 3-step process in detail. Then I’ll round things out by offering a few bonus tips for keeping your dishwasher working in tip-top shape! :-)
How It Works
The cleaning process I came up with relies on a few of my favorite cleaning ingredients: white vinegar and baking soda. White vinegar helps to remove grime, dissolve mineral deposits, and sanitize your dishwasher. And using baking soda helps to remove lingering odors and scrub away stuck-on food bits, residues, and stains.
Every time I use this method, it leaves my dishwasher squeaky clean, smelling fresh, and it solves any drainage issues. Here’s how it’s done!
How To Clean Your Dishwasher
Step 1 – Inspect The Drain
Before you start cleaning you dishwasher, it’s a good idea to quickly check the area around the drain. Remove the bottom rack for easier access, then feel the area around the drain.
Remove any foreign material you find to prevent it from blocking the drain. (You’d be surprised at what repairmen often find down there—bones, crab shells, glass shards, bits of plastic, etc.)
This is also a good opportunity to inspect the holes in the spray arm. If they look grimy, dip an old toothbrush into some vinegar and use it to scrub any food particles out the the spray holes. Replace the bottom rack when you’re done.
Step 2 – Vinegar Wash
Set a small dishwasher-safe bowl on the top rack of your empty dishwasher, then fill it with white vinegar. Close your dishwasher and run a complete wash cycle on the hottest setting.
Step 3 – Baking Soda Wash
Once the first wash cycle is finished, sprinkle a handful of baking soda into the bottom of your dishwasher. Run it through another quick wash cycle using the hottest water setting.
Optional Step – Bleach Wash
If you’ve been struggling with mold and/or mildew in your dishwasher, adding a final bleach wash to the cleaning process should take care of it. To do a bleach wash, add 1 cup of bleach to the bottom of the dishwasher and run a full wash cycle.
(Note: Do NOT do this step if your dishwasher has a stainless steel interior. Bleach can permanently damage and discolor stainless steel.)
Repeat the steps outlined above every 3 months or so to keep your dishwasher clean and working effectively!
5 Bonus Dishwasher Tips
- Run your garbage disposal to clear it out before starting a load of dishes. Dishwashers usually drain into the same pipe as your sink, so that drain must be clear.
- Before starting a load of dishes, run hot water through your sink faucet until it feels hot to the touch. Your dishwasher will perform better if the wash cycle starts with hot water.
- Set your water heater high enough to ensure that the water can clean your dishes effectively. Your water heater should be set to around 120°F (50°C.) Cooler water won’t clean effectively, and hotter water could scald someone accidentally!
- Running only full loads of dishes helps to conserve water and energy, but don’t overfill your dishwasher. Dishwashers work by spraying water over the dishes, so the water needs to be able to get to the dishes in order to clean them.
- You can rinse dirty dishes before putting them in the dishwasher, but don’t over-rinse your dishes. Dishwasher detergent requires a certain amount of gunk and grime to work right. Otherwise, the detergent can foam up during the cycle, which isn’t good for your dishwasher.
