         fabric upholstery. Products and methods designed for leather should
         be selected with regard to its finish and condition.",

        "Can all leather sofas be professionally cleaned?",

    answer:
        "Many leather sofas can be professionally cleaned, but suitability
         and method depend on the leather type, finish and overall condition.
         A pre-cleaning assessment is required to determine an appropriate

        "Will professional cleaning remove every mark?",

    answer:
        "No universal guarantee should be made. Some everyday marks and
         surface soiling may improve, but results depend on the nature of the
         mark, existing wear, previous treatment and the leather's condition.",

DEFINE_FAQ FAQ_ID:WHY_INSPECT_BEFORE_CLEANING {
    question:
        "Why is the leather inspected before cleaning?",

        "How often should leather furniture be professionally cleaned?",
