how to clean second hand sofa

[OSerenity]

To clean a second-hand sofa, first vacuum all surfaces to remove dust and crumbs. Treat stains with a gentle upholstery cleaner and sprinkle baking soda to neutralize odors. For a more thorough clean, use a steam cleaner or a mixture of mild soap and water or vinegar, and allow the sofa to air dry completely before use.
