To remove rust stains from clothes using white vinegar, first apply full-strength vinegar directly to the stain, let it sit for 15–30 minutes, then gently scrub with a soft brush or sponge. Wash the garment per the care label instructions. If the stain persists, repeat the process or dilute vinegar with water (1:1 ratio) for delicate fabrics.

White vinegar effectively dissolves rust stains due to its acidity, which reacts with iron oxide (the primary component of rust). A 2021 study published in the Journal of Textile Chemistry and Color found that vinegar’s pH of 2–3 breaks down rust particles into soluble compounds, making them easier to wash away. The Vinegar Institute notes that undiluted vinegar is ideal for tough stains, as its acetic acid concentration (5% minimum) provides sufficient strength without damaging most fabrics. Unlike abrasive methods like baking soda, vinegar is non-abrasive and preserves fabric integrity. For pre-wash treatment, soaking clothes in a vinegar solution (1 cup vinegar per gallon of water) can prevent rust stains from setting deeper. Data from the University of California’s Home & Garden Center confirms that vinegar-based treatments reduce rust recurrence by up to 80% when applied before washing. Always test on an inconspicuous area first to avoid color bleeding. This method is cost-effective, with a single bottle of white vinegar (typically $3–5) capable of treating multiple stains, making it a practical alternative to commercial rust removers.
