MAPICan You Use Vinegar in a Dishwasher?
Vinegar is often suggested as a low-cost way to deal with odors, mineral deposits, and interior buildup, but 'put vinegar in the dishwasher' is too vague to be good advice. Appliance manufacturers specify different amounts, rack positions, and cycles, and some explicitly warn against excessive use. Vinegar should therefore be treated as an occasional cleaning method when the manufacturer allows it—not as a universal dishwasher detergent replacement or an ingredient to pour randomly into the machine.
Yes, on some dishwashers and for certain cleaning tasks—but follow your model's instructions. Whirlpool describes using white vinegar in a dishwasher-safe container during an empty cleaning cycle, while LG also recommends placing vinegar in a bowl rather than pouring it directly into the base and warns that excessive use may damage the appliance.

The answer
You can use white vinegar in some dishwashers for occasional interior cleaning when the manufacturer permits it. The safest approach is to follow the instructions for your exact model. Do not assume that vinegar belongs in the detergent dispenser or should be poured directly into the bottom of the machine.
Why
Vinegar is acidic, which makes it useful for loosening some mineral deposits and helping with odors and buildup. That acidity is also why the method matters. Whirlpool instructs users to place white vinegar in a dishwasher-safe measuring cup or container and run an empty cycle, and notes that using vinegar too often could damage the dishwasher. LG similarly tells users to place vinegar in a shallow bowl on a rack, not pour it directly into the base, and warns against excessive use. These examples show why model-specific manufacturer guidance is more reliable than a single universal recipe.
When it is usually OK
- Your dishwasher manufacturer explicitly allows white vinegar for interior or machine cleaning.
- You use the amount, container, rack position, and cycle recommended for your model or brand.
- The dishwasher is empty if the manufacturer's procedure calls for an empty cleaning cycle.
- You are using vinegar occasionally for cleaning or deodorizing rather than as a substitute for regular dishwasher detergent.
- You keep vinegar separate from cleaning chemicals that the manufacturer does not instruct you to combine.
When you should not
- Your owner's manual says not to use vinegar, acids, or non-approved cleaners.
- You plan to pour vinegar directly into the dishwasher base even though your manufacturer's instructions say to use a bowl or measuring cup.
- You are planning to use vinegar during every wash cycle as a routine additive without manufacturer approval.
- You intend to replace automatic dishwasher detergent with vinegar.
- You are unsure whether another chemical or cleaning product already in the machine can safely be used with vinegar.
Risks and exceptions
- Excessive or repeated acid exposure may damage some dishwasher materials or components; LG and Whirlpool both caution against excessive or overly frequent vinegar use in their cleaning guidance.
- Pouring vinegar into the wrong location can expose areas that were not intended for direct acid contact.
- Using vinegar instead of dishwasher detergent may leave food soil, grease, and other residues that detergent is designed to remove.
- Following generic online quantities instead of the appliance instructions can lead to a method that is unsuitable for your specific machine.
- Mixing vinegar with other household chemicals can create unsafe reactions; do not combine cleaners unless the manufacturer explicitly instructs you to do so.
Best practice
Look up the Use & Care guide for your exact dishwasher model first. If vinegar is approved, follow that procedure exactly. A common manufacturer pattern is to put white vinegar in a dishwasher-safe bowl or measuring cup on a rack and run an empty cycle without detergent, but quantities and cycle choices vary. Clean the dishwasher filter separately as directed by the manufacturer, because vinegar does not replace physical removal of trapped food debris.
Alternatives
- A manufacturer-approved dishwasher cleaner or descaler
- Cleaning the removable filter with running water and a soft brush as directed by the manual
- Cleaning clogged spray-arm holes according to the manufacturer
- Using a machine-clean or tub-clean cycle with the approved cleaner for that appliance
- Contacting manufacturer support when odors, standing water, or poor cleaning continue after routine maintenance
Frequently asked questions
Where should you put vinegar in a dishwasher?
Follow your model's instructions. Whirlpool and LG both describe methods that place white vinegar in a dishwasher-safe cup or bowl on a rack rather than simply pouring it into the machine. LG specifically warns not to pour vinegar directly into the base in one of its cleaning guides.
Can you put vinegar in the dishwasher detergent dispenser?
Do not do this unless your dishwasher's manufacturer specifically tells you to. The official procedures used as sources for this article place vinegar in a separate dishwasher-safe container on a rack.
Can vinegar replace dishwasher detergent?
No. Vinegar may be used for certain cleaning or deodorizing procedures, but it is not a substitute for automatic dishwasher detergent during normal dishwashing.
Can too much vinegar damage a dishwasher?
It can be a concern. Whirlpool says using vinegar too often could damage the dishwasher, and LG warns that excessive vinegar use may cause appliance damage. This is why occasional, manufacturer-directed use is preferable to routine use.
Should the dishwasher be empty when cleaning it with vinegar?
Often yes, depending on the manufacturer's procedure. Whirlpool's cleaning guidance starts with an empty dishwasher, and LG's cleaning instructions also call for removing dishes before a vinegar cleaning cycle.
