The best way to clean a leather sofa is to remove all dust and soil from the surface of the leather with a vacuum cleaner, then apply a cleaning product with a soft cloth. A leather conditioner helps restore the material's original suppleness while protecting it against future damage.
Always test any cleaners or conditioners on a small, hidden part of the sofa to ensure there are no negative reactions to the chemicals in the product.
Step 1: Vacuum the sofa
Using the wand attachment, vacuum the surface of the leather sofa, as well as between and behind cushions. This sweeps up dust, soil and crumbs. Wipe the sofa with a microfiber cloth to eliminate any remaining particles.
Step 2: Clean the sofa
Apply a leather cleaner to any stains on the sofa. The appropriate cleaner depends on the type of stain. For example, ink stains are often lifted with alcohol applied with a cotton swab, while many stains respond to a commercial cleaner or a solution of lemon juice and cream of tartar. Use a soft, clean cloth, then buff out the leather cleaner.
Step 3: Condition the leather
Experts recommend conditioning the leather after cleaning it. A commercial leather conditioner or a mixture of saddle soap and warm water will suffice. Apply it with a soft cloth, then buff it out after 30 minutes.
