To effectively remove nail varnish from a sofa, a careful and methodical approach is necessary to avoid damaging the fabric. The first and most critical step is to test your chosen cleaning solution on an inconspicuous area of the upholstery, such as an inside seam or a spot on the back, to ensure it does not cause any discoloration or damage.
The recommended agent for this task is a non-acetone nail polish remover. Acetone-based removers can be overly harsh and may permanently damage or even dissolve certain synthetic fabrics like acetate or micro-suede. If the nail varnish spill has already dried, you can begin by gently scraping away any excess, hardened polish using a dull tool like a butter knife or a spoon.
To apply the remover, dampen a clean, white cloth with the non-acetone solution rather than pouring it directly onto the sofa. Gently blot the stain with the cloth. It is important to blot instead of rub, as rubbing can spread the stain and push it deeper into the fabric fibers. To contain the stain, start blotting from the outer edges and work your way toward the center. As the varnish transfers from the sofa to the cloth, be sure to switch to a clean section of the cloth to avoid re-staining the area.
Once the nail varnish has been lifted, the final step is to clean the spot to remove any residue from the polish remover. Use a new cloth dampened with water and a small amount of mild dish soap or an appropriate upholstery cleaner to blot the area. Follow this by blotting with a clean, dry towel to absorb any excess moisture and allow the spot to air dry completely.
