Removing a nail polish stain from a leather sofa requires a careful and methodical approach to avoid damaging the material's finish. It is critical to first perform a spot test on an inconspicuous area of the sofa, such as the underside of a cushion, before applying any cleaning solution directly to the visible stain. This ensures the chosen method will not cause discoloration or damage.
For the removal process, a non-acetone nail polish remover is the recommended cleaning agent. Acetone-based removers are typically too harsh and can strip the color and protective coating from the leather. Begin by lightly dampening a cotton swab with the non-acetone remover. Gently dab at the nail polish stain, working carefully from the outside edges inward to prevent the stain from spreading. Avoid aggressive rubbing, as this can push the pigment deeper into the leather's pores. As the polish transfers to the swab, switch to a fresh one to avoid reapplying the stain.
Once the stain has been lifted, you must clean the area to remove any solvent residue. Mix a solution of mild soap and warm water. Dip a clean, soft cloth into the soapy water and wring it out until it is just damp. Gently wipe the affected area, then follow up with another cloth dampened with only plain water to rinse away the soap. Pat the spot completely dry with a clean towel. Because solvents can dry out the material, applying a high-quality leather conditioner to the treated area is a crucial final step to restore moisture and protect the sofa's finish. If the stain persists, consulting a professional leather cleaning specialist is the safest alternative.
