Why Put Vinegar In Dishwasher

In our quest for cleaner and more efficient ways to maintain our household appliances, vinegar has emerged as a popular and cost-effective solution. One intriguing practice that has gained traction in recent years is putting vinegar in the dishwasher. But what is the rationale behind this seemingly unconventional idea, and does it really work? In this article, we’ll explore the benefits and drawbacks of using vinegar in your dishwasher, providing you with a comprehensive guide to make informed decisions about this household hack.

The Science Behind Vinegar

Before delving into the specifics of using vinegar in the dishwasher, it’s essential to understand the science behind it. Vinegar, primarily composed of acetic acid, serves as a powerful natural cleaner. Its acidity can break down mineral deposits, grease, and soap scum – all of which commonly accumulate in dishwashers. This makes vinegar an attractive option for maintaining the cleanliness and functionality of your appliance.

Benefits of Using Vinegar in the Dishwasher

1. Limescale and Mineral Deposit Removal

Vinegar’s acidic nature makes it excellent for dissolving limescale and mineral deposits that can clog your dishwasher’s spray arms, nozzles, and filters. Regular use can prevent these deposits from building up and potentially damaging your machine.

2. Improved Dishwashing Performance

When your dishwasher’s internal components are free from residue and buildup, it can operate more efficiently. This means cleaner dishes, reduced water spots, and better overall performance.

3. Odor Elimination

Dishwashers can develop unpleasant odors over time due to trapped food particles and residue. Vinegar’s natural ability to neutralize odors can leave your dishwasher smelling fresh.

4. Environmentally Friendly

Using vinegar as a dishwasher cleaner is environmentally friendly compared to harsh chemical alternatives. It’s a natural, non-toxic option that reduces your carbon footprint.

How to Use Vinegar in Your Dishwasher

Now that you know the advantages, here’s how to put vinegar to work in your dishwasher effectively:

1. Empty the Dishwasher

Start with an empty dishwasher. Remove any dishes, racks, and utensil holders to access all interior components.

2. Fill a Bowl with Vinegar

Pour a cup of white vinegar into a dishwasher-safe bowl or container. Place it on the top rack of your dishwasher.

3. Run a Hot Cycle

Set your dishwasher to the hottest and longest cycle available. This will allow the vinegar to circulate and clean the interior thoroughly.

4. Wipe Down the Exterior

While the dishwasher is running its cycle, take a moment to wipe down the exterior with a cloth and mild soapy water.

5. Regular Maintenance

Repeat this process once a month to maintain a clean and odor-free dishwasher.

Drawbacks and Considerations

While using vinegar in the dishwasher offers numerous benefits, there are some considerations to keep in mind:

1. Vinegar Smell

Some people may not appreciate the lingering smell of vinegar in their dishwasher. However, this can be mitigated by using less vinegar or following up with a rinse cycle.

2. Not Suitable for All Dishwashers

Check your dishwasher’s user manual to ensure that using vinegar as a cleaner won’t void your warranty. Some manufacturers discourage it.

3. Pre-rinse Dishes

For heavily soiled dishes, pre-rinsing may still be necessary, even when using vinegar. Vinegar works best as a maintenance and preventive measure.


Incorporating vinegar into your dishwasher cleaning routine can be an effective and eco-friendly way to maintain the functionality and hygiene of your appliance. It helps prevent mineral buildup, improves cleaning performance, and eliminates unpleasant odors. However, it’s essential to be mindful of potential drawbacks and follow the recommended guidelines for best results.

Now that you have a clearer understanding of why you should put vinegar in your dishwasher, it’s time to take action and enjoy cleaner, more efficient dishwashing.
