"Every three months, fill up a bucket and treat your sofa to a good washing with saddle soap, which is available at most feed or hardware stores. For a very light protective finish, apply a thin coat of olive oil with a microfiber cloth, allow it to sit for one-half hour and then buff it off with a clean rag."
