The answer to tough stains on upholstery cleaning is to use a combination of professional-grade cleaning solutions and techniques. Common causes of tough stains include spills, pet accidents, and ground-in dirt and grime. Symptoms may include discoloration, odors, and matted or worn fabric.
For DIY upholstery cleaning, start by blotting the stain with a clean, white cloth to absorb as much of the spill as possible. Then, use a mild detergent or specialized upholstery cleaner and gently scrub the area with a soft-bristle brush. Avoid rubbing the stain, as this can spread it and damage the fabric. If the stain persists, consider renting a professional-grade steam cleaner or calling in a professional upholstery cleaning service.
