Can You Use Vinegar and Laundry Detergent Together? Here’s What You Should Know
Vinegar and laundry detergent can both have a place in your laundry routine, but they shouldn’t be mixed together in the same compartment or combined directly.
Laundry detergent is formulated to clean dirt, oils, and stains, while distilled white vinegar is sometimes used as a rinse-stage additive. Keeping them separate allows the detergent to work during the wash before the vinegar is introduced during rinsing.
Why Use Vinegar in Laundry?
Laundry detergent should remain the main cleaning product in your routine.
Distilled white vinegar is sometimes used during the rinse cycle to help reduce lingering odors and rinse away some detergent residue. It can be particularly useful for items such as towels and washable cleaning cloths that may develop a stale smell over time.
However, vinegar isn’t a substitute for detergent. It doesn’t provide the same cleaning action as a properly formulated laundry detergent.
Don’t Pour Vinegar Directly Into the Detergent
One of the most important rules is to avoid combining vinegar and laundry detergent directly.
Vinegar is acidic, while laundry detergents are formulated with a specific chemical balance. Mixing them together can interfere with the cleaning process and makes little sense when the products can simply be used at different stages.
Instead, let the detergent handle the wash cycle and, if your machine and clothing manufacturer allow it, use vinegar during the rinse stage.
How to Use Vinegar in the Washing Machine
If your washing machine has a fabric-softener dispenser, you can add distilled white vinegar there so the machine releases it during the rinse cycle.
A simple routine is:
- Add your normal amount of laundry detergent to the detergent compartment.
- Add a modest amount of distilled white vinegar to the fabric-softener compartment.
- Start the wash cycle.
- Allow the machine to release the vinegar during the rinse rather than mixing it with the detergent at the beginning.
Always check your washing machine’s instructions first. Some manufacturers advise against using vinegar regularly because its acidity may affect certain rubber components over time.
Which Vinegar Should You Use?
If you choose to use vinegar for laundry, use plain distilled white vinegar.
It’s colorless and doesn’t contain the pigments found in darker varieties.
Avoid using cooking vinegars such as balsamic vinegar, red wine vinegar, or malt vinegar in your washing machine.
When Might Vinegar Be Useful?
Some people use distilled white vinegar occasionally when washing:
- Towels
- Workout clothing
- Cleaning cloths
- Everyday washable fabrics with lingering odors
It’s best viewed as an optional rinse-stage addition rather than something required for every load.
Can Vinegar Replace Laundry Detergent?
No.
Laundry detergent is specifically formulated to remove dirt, body oils, soils, and other contaminants from fabrics.
Vinegar doesn’t provide an equivalent cleaning system, so replacing detergent with vinegar isn’t a reliable way to clean clothes.
If your laundry is heavily soiled, use an appropriate detergent and follow the garment’s care instructions.
What About Fabric Softener?
If you’re using vinegar in the rinse compartment, don’t automatically assume you should also add conventional fabric softener.
For towels in particular, excessive fabric softener can reduce absorbency because it leaves conditioning ingredients on the fibers.
If you’re considering vinegar as an alternative to fabric softener, check your washer’s manual and remember that vinegar isn’t an officially recommended replacement for every machine or fabric.
Important Safety Rule: Never Mix Vinegar With Bleach
This is especially important.
Never combine vinegar with chlorine bleach.
Mixing acids such as vinegar with chlorine bleach can produce dangerous chlorine gas.
If you’re using bleach in a laundry load, follow the bleach manufacturer’s instructions and don’t add vinegar to the same cycle unless the product and machine instructions specifically permit it.
Check Your Machine’s Manual
Before making vinegar part of your regular laundry routine, check the manufacturer’s recommendations for your washing machine.
This is particularly important for newer high-efficiency machines and machines with rubber seals or components that may be affected by repeated exposure to acidic products.
Also follow the care labels on your clothing, especially for delicate fabrics.
The Bottom Line
You can use laundry detergent and distilled white vinegar in the same wash load, but the safest approach is to keep them separate rather than mixing them together.
Use detergent for the actual cleaning stage and, if your machine’s instructions allow it, put a modest amount of distilled white vinegar in the rinse compartment.
Vinegar is optional—not a replacement for detergent—and it should never be mixed with chlorine bleach.
Used appropriately, it can be a simple occasional addition to a laundry routine, particularly when you’re trying to freshen washable items such as towels or workout clothes.
