Regularly, remove dust and debris, and spot-clean any spills or stains as soon as they occur. Depending on the specific type of fabric, you may also need to use a gentle detergent or upholstery cleaner to remove deeper stains or grime. Additionally, it is important to protect your fabric sofa from excessive sunlight or heat, as these can cause fading or damage over time. By following these simple steps, you can easily maintain your fabric sofa and extend its lifespan.
