<human>:  What is the best way to clean a leather sofa?
<bot>: The best way to clean a leather sofa is to use a damp cloth and a mild leather cleaner or saddle soap, or a combination of the two, in order to remove any dirt, dust, or debris. It is important to test any cleaners first on an inconspicuous area to ensure that it won’t damage the leather, as some products can be too harsh for the material. Additionally, after cleaning, be sure to condition the leather with a commercially available leather conditioner, as this will not only help to preserve the furniture’s beauty and luster, but will also help to prevent any cracking or premature wear.
