The answer to 'why is my upholstery dusty' is that upholstery can become dusty over time due to a few common causes. Dust, pet dander, and other airborne particles can settle into the fibers of your upholstered furniture, making it appear dull and discolored. This is especially common in homes with poor air circulation, high traffic areas, or if the furniture is not cleaned regularly.
To prevent and address dusty upholstery, it's important to vacuum the furniture weekly using the upholstery attachment, and occasionally use a fabric-safe cleaner to wipe down the surfaces. Placing the furniture away from direct airflow, such as vents or windows, can also help reduce dust buildup. If the issue persists or the upholstery is heavily soiled, it's best to call a professional cleaning service to deep clean the furniture and restore its appearance.
