This method works effectively on cotton, linen, silk, denim, and most other fabrics. Proceed with caution if the item in question contains acetate or triacetate since the nail polish remover melts fabrics containing these chemicals.

Continue rinsing the fabric and applying more acetone until the paper towels no longer turn the color of the nail polish after blotting; this indicates the stain has been removed. Check the stained area one final time for traces of nail polish. If you see a little color left, dip a cotton ball in acetone and gently remove it.

Don’t smear the polish so it covers, even more, surface area on the upholstery; rather, use the paper towel to wipe it off with short swipes that don’t spread the polish around. Use the most absorbent cloth or paper towels you can, so you’re leaving as little polish as possible to soak into the upholstery.

You may want to do a test dab on a part of the upholstery that’s usually hidden. Acetone reacts with some types of fabric, including those containing acetate or triacetate, and could make the stained area look worse if you aren’t careful. Do not pour the acetone onto the stained fabric since it’s harder to control where it flows if you don’t use an applicator like a cotton swab or the corner of a paper towel.

Dab the area with peroxide, blot it with a clean towel and repeat until the stain is gone. Hydrogen peroxide can act as a bleaching agent, so test it on an unnoticeable area of the upholstery before using it on the stained area.
