How to Remove Set-In Red Wine from a Polyester Couch Cushion

1. Blot the stain with a dry cloth. Press gently to absorb any remaining moisture. Do not rub, as that can push the wine deeper into the fibers.
2. Mix a cleaning solution. In a spray bottle, combine 1 cup of lukewarm water, 1 tablespoon of white vinegar, and 1 teaspoon of dish soap. Shake gently to mix.
3. Test the solution. Spray a small, hidden area of the cushion (like the underside) and blot with a white cloth. Wait 10 minutes to check for color bleeding or damage.
4. Apply the solution to the stain. Spray the stained area generously, but do not soak it. Let it sit for 5–10 minutes to loosen the wine.
5. Blot the stain. Using a clean white cloth, blot from the outside edge toward the center. This prevents the stain from spreading. Keep blotting until you see the wine transferring to the cloth.
6. Rinse the area. Dampen a clean cloth with plain water and blot the area to remove any soapy residue.
7. Blot dry. Press with a dry cloth to absorb excess moisture.
8. Apply baking soda paste. Mix 3 parts baking soda with 1 part water to form a thick paste. Spread it over the stain and let it dry completely (about 1–2 hours). The baking soda will help pull out remaining wine and odors.
9. Vacuum or brush off the baking soda. Once dry, vacuum the area or use a soft brush to remove the powder.
10. Repeat if needed. If the stain is still visible, repeat steps 4–9. Some set-in stains may require two or three treatments.

What Not to Do

• Avoid rubbing. Rubbing can damage the polyester fibers and spread the stain.
• Do not use hot water. Hot water can set the wine stain further. Always use lukewarm or cold water.
• Avoid bleach. Bleach can discolor or weaken polyester. Stick to gentle cleaners.
• Do not use a steam cleaner. High heat can set the stain permanently.

Fresh vs. Set-In Stains

If the wine is fresh, blot it immediately with a dry cloth, then apply the vinegar-dish soap solution. Fresh stains usually lift with one treatment. For set-in stains, the baking soda paste is especially helpful. The longer the wine sits, the more it bonds to the fibers, so be patient and repeat the process as needed.

Alternative Methods

If the vinegar-dish soap solution doesn’t work, you can try a commercial upholstery cleaner designed for synthetic fabrics. Always test it in a hidden area first. Another option is to use a mixture of hydrogen peroxide and dish soap, but test it on a small area first because hydrogen peroxide can lighten some fabrics.
