The answer to 'when to clean upholstery' is that it's generally recommended to have your upholstered furniture professionally cleaned every 12-24 months, depending on the amount of use and wear. Regular cleaning helps extend the life of your upholstery and keep it looking its best. High-traffic areas like sofas and chairs may need more frequent cleaning, while less-used pieces can often go longer between cleanings.
Professional upholstery cleaning uses specialized equipment and techniques to thoroughly clean the fabric, removing deep-set dirt, stains, and odors. This is important for maintaining the appearance and condition of your furniture, as well as promoting a healthier indoor environment by removing allergens and other contaminants.
