To remove dried nail polish from a sofa, begin by gently scraping off as much of the excess polish as you can. You can use a dull-edged tool like a spoon or a credit card for this. Be careful not to snag or damage the fabric.
Before applying any cleaning solution, it is crucial to test it on an inconspicuous spot of the sofa, such as the underside of a cushion or a seam on the back. This will ensure the solution does not discolor or damage the fabric.
For the cleaning solution, non-acetone nail polish remover is often the safest and most effective option. Apply a small amount to a clean, white cloth or a cotton swab, not directly onto the stain. Gently blot the nail polish stain, working from the outside edges inward to prevent it from spreading. Do not rub, as this can push the stain deeper into the fibers. As the polish transfers to the cloth, switch to a clean section to avoid reapplying the stain. Other potential solutions include rubbing alcohol or hairspray, which should also be tested first and applied in the same blotting manner. Acetone can be effective but should be used as a last resort, as it can permanently damage synthetic fabrics.
Once the nail polish stain is removed, you may need to clean the spot to remove any residue from the cleaning agent. Mix a small amount of mild dish soap with water and use a clean cloth to blot the area. Follow this by blotting with a cloth dampened with plain water to rinse the soap away. Finally, pat the area dry with a clean towel and allow it to air dry completely.
