how to remove red wine stains

To remove a red wine stain, blot the spill immediately with a clean white cloth and avoid rubbing or using heat, which can set the stain permanently.

Blot, Do Not Rub. Blot the stain gently with a clean white cloth or paper towel, working from the outside toward the center to prevent spreading. Never rub or scrub, as this drives the pigment deeper into the fibers.
Avoid Heat and Hot Water. Use only cold water for rinsing or diluting. Hot water, steam, and dryer heat will permanently set the wine's tannins and pigments into the fabric.
Use Household Cleaning Agents. For fresh spills, sprinkle salt or baking soda to absorb excess liquid. For residual stains, a mixture of dish soap and hydrogen peroxide (for light fabrics) or distilled white vinegar can help break down the pigment.
Handle Delicates with Care. If the item is silk, wool, velvet, or labeled dry-clean only, avoid home treatments and take it to a professional cleaner as soon as possible. Always spot-test any cleaner first.
