The removal of nail polish from couch upholstery requires a careful approach, as the solvents capable of dissolving the polish can also damage the fabric's dye and fibers. Based on user experiences, a few methods can be considered, but it is imperative to first test any cleaning agent on a small, inconspicuous area of the couch, such as a spot on the back or underneath a cushion, to observe for any adverse reactions like color fading or material degradation.
One common method involves the use of nail polish remover. Non-acetone nail polish remover is often suggested as it is less harsh than its acetone-based counterpart. However, even non-acetone removers carry a risk of lifting the couch's color. To use this method, one would apply a small amount of the remover to a cloth and gently blot the stain. Rubbing should be avoided as it can spread the polish and embed it deeper into the fabric. Acetone-based removers should be used with extreme caution, if at all, as they are known to melt certain synthetic fibers, such as those found in microfiber.
An alternative method that has proven effective for some is the application of hairspray. According to one account, spraying hairspray directly onto the nail polish stain, allowing it to sit for a short period, and then scrubbing the area can successfully lift the polish. This technique was reported to cause less color fading on a microfiber couch compared to non-acetone remover. For spills that are still wet, it is advisable to blot up as much excess as possible before treatment. For dried, thick spills, carefully scraping or peeling off the hardened polish may be an effective first step before treating the remaining stain with a solvent. Stronger commercial products like Goof Off are also an option, but due to their potency, they present a high risk of damage and must be tested thoroughly.
