Yes, furniture made of 100% polyester is generally easy to clean. Polyester is a synthetic material that is resistant to staining and fading, making it ideal for furniture. To clean polyester furniture, you can usually use a mild detergent mixed with water and a soft cloth or sponge. Gently blot the stained area and avoid rubbing vigorously, as this may damage the fabric. It's important to check the care instructions provided by the manufacturer for specific cleaning recommendations, as some polyester fabrics may require professional cleaning.
