What Usually Helps With Vinegar Washer—and What Makes It Worse

You want to use vinegar in your washer and get the best results. Maybe you’ve heard that vinegar deodorizes, softens, or cleans the machine. Vinegar is a versatile laundry additive that can improve your results when used correctly. Here’s what usually helps with vinegar in the washer and what makes it worse.

Vinegar (white distilled vinegar) is a mild acid that deodorizes clothes, softens fabric, removes detergent residue, brightens colors, and cleans the washing machine. It works by neutralizing alkaline compounds (detergent, hard water minerals) and killing some bacteria and mold. The key to using vinegar in the washer is adding it to the rinse (not the wash), using the right amount, and not mixing it with baking soda in the same cycle.

To use vinegar in the washer, add half a cup to the fabric softener dispenser for the rinse, use it with Tide Free and Gentle and baking soda (in the wash), use it for deodorizing and softening, and clean the machine monthly with affresh. Don’t add vinegar to the wash with baking soda, don’t use too much, and don’t use it on silk or acetate.

What Helps

Deodorizes Clothes

Vinegar neutralizes odor molecules. Add half a cup to the rinse for sweaty gym clothes, musty towels, or smelly work clothes. The vinegar smell dissipates as clothes dry.

Softens Fabric

Vinegar removes detergent residue that makes clothes stiff. Add half a cup to the rinse for naturally soft clothes without fabric softener.

Removes Detergent Residue

Vinegar dissolves detergent and hard water residue that builds up on clothes and in the machine. Add half a cup to every rinse to prevent buildup.

Brightens Colors

Vinegar helps remove dulling residue from clothes, brightening colors. Add half a cup to the rinse for colored clothes.

Brightens Whites

Vinegar helps remove yellowing residue from whites. Add half a cup to the rinse with OxiClean in the wash for bright whites.

Cleans the Washing Machine

Vinegar helps clean the washer by dissolving mineral deposits and residue. Run an empty hot cycle with 2 cups of vinegar. Follow with affresh Washing Machine Cleaner monthly for deep cleaning.

Kills Some Bacteria and Mold

Vinegar kills some bacteria and mold species. Add half a cup to the rinse for disinfecting. For full disinfecting, add Lysol Laundry Sanitizer.

Removes Stains

Vinegar can help remove some stains. Apply full strength to deodorant stains, coffee stains, and rust stains. Let sit for 15 minutes and wash.

Works with Other Products

Vinegar works well with:

• Tide Free and Gentle (detergent, in the wash)
• Arm and Hammer Baking Soda (booster, in the wash)
• OxiClean Max Force Spray (stain remover, pre-treat)
• Dawn Ultra Dish Soap (grease remover, pre-treat)
• Shout Advanced Grease Busting Foam (food stain remover, pre-treat)
• Amodex Ink and Stain Remover (ink remover, pre-treat)

What Makes It Worse

Adding Vinegar to the Wash with Baking Soda

Vinegar and baking soda neutralize each other, producing water and carbon dioxide. If you add both to the wash, neither works. Add baking soda to the wash and vinegar to the rinse.

Using Too Much Vinegar

Using too much vinegar can damage rubber seals and hoses in the washing machine over time. Use half a cup per load. Don’t use more than 1 cup.

Using Vinegar on Silk or Acetate

Vinegar is acidic and can damage delicate fabrics like silk and acetate. Don’t use vinegar on silk, acetate, or rayon.

Adding Vinegar to the Wash Cycle

Adding vinegar to the wash cycle can reduce the effectiveness of detergent. Add vinegar to the rinse cycle only, using the fabric softener dispenser.

Using Vinegar Instead of Detergent

Vinegar is not a detergent. It doesn’t contain surfactants to break down dirt and oil. Always use it with Tide Free and Gentle.

Using Vinegar Instead of Disinfectant

Vinegar kills some bacteria and mold but not all. For full disinfecting, use Lysol Laundry Sanitizer. Don’t rely on vinegar alone for disinfecting.

Pouring Vinegar Directly on Clothes

Pouring vinegar directly on clothes can cause spotting on some fabrics. Add vinegar to the dispenser, not directly on clothes.

How to Use Vinegar in the Washer

In the Rinse Cycle

Add half a cup of white vinegar to the fabric softener dispenser. The dispenser releases vinegar during the rinse cycle. This is the best way to use vinegar in laundry.

For Machine Cleaning

Run an empty hot cycle with 2 cups of vinegar to clean the washer. Follow with affresh monthly for deep cleaning.

As a Pre-Treatment

Apply vinegar full strength to stains like deodorant, coffee, or rust. Let sit for 15 minutes. Wash normally.

As a Soak

Soak clothes in a solution of 1 cup vinegar and water for 30 minutes for tough odors. Wash normally.
