The answer to 'DIY upholstery cleaning' is that it is generally possible to clean upholstered furniture at home, but it requires some care and preparation to avoid damage. Proper techniques and products are important to safely clean and maintain the fabric without shrinking, discoloring, or damaging the material.
Start by thoroughly vacuuming the upholstery to remove any loose dirt or debris. Then, use a mild, water-based upholstery cleaner and a soft-bristle brush to gently scrub the fabric. Avoid using too much water or harsh chemicals, which can soak through the fabric and damage the underlying materials. Allow the upholstery to fully dry before using the furniture again.
