What Does Vinegar Do for Laundry? Benefits and Uses

You’ve heard that vinegar is good for laundry. People say it softens clothes, removes odors, and brightens colors. But you’re not sure what vinegar actually does or how to use it. Vinegar is a natural laundry booster that does several things: it deodorizes, softens, brightens, removes residue, and kills bacteria. Here’s what vinegar does for laundry and how to use it.

Vinegar in laundry is the use of white vinegar (acetic acid) as a natural laundry booster and fabric softener. Vinegar deodorizes by neutralizing acids, softens clothes by removing detergent residue and hard water minerals, brightens colors by removing residue, removes detergent and fabric softener buildup, and kills bacteria and mold.

To use vinegar in laundry, add half a cup of white vinegar to the fabric softener dispenser for a normal load. Use 1 cup for heavy odors. Don’t mix with chlorine bleach, don’t use more than 1 cup per load for clothes, and don’t use on silk or wool. Use baking soda in the wash and vinegar in the rinse for best results.

What Vinegar Does for Laundry

1. Deodorizes

Vinegar neutralizes acids that cause odors. It removes sweat, food, smoke, and musty smells from clothes. The vinegar smell disappears when clothes dry.

2. Softens Clothes

Vinegar removes detergent residue and hard water minerals that make clothes stiff. It’s a natural alternative to fabric softener. Clothes come out softer without a waxy coating.

3. Brightens Colors

Vinegar removes residue that makes colors look dull. Clothes come out brighter and cleaner. Add half a cup to the rinse for every load.

4. Whitens Whites

Vinegar removes yellowing caused by detergent residue and hard water. For best results, combine with baking soda in the wash and dry in the sun.

5. Removes Residue

Vinegar removes detergent and fabric softener residue from clothes and the washing machine. This keeps clothes soft and the machine clean.

6. Kills Bacteria

Vinegar kills most bacteria and mold, which helps remove odors and prevent mildew.

7. Removes Stains

Vinegar helps break down some stains, including coffee, tea, and deodorant stains. Pre-soak in vinegar and water before washing.

8. Cleans the Washing Machine

Vinegar removes mineral deposits and detergent residue from the washing machine. Run 2 cups of vinegar in an empty hot cycle monthly.
