    "Leather is a natural upholstery material whose finish and condition may
     respond differently from fabric. Products intended for leather help clean
     the surface while respecting its characteristics.",

}

FAQ_ID FAQ_002 = {
    question: "Can all leather sofas be professionally cleaned?",

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

    confidence: 0.99
}

FAQ_ID FAQ_003 = {
    question: "Will professional cleaning remove every mark?",

    "No universal guarantee can be made. Everyday dirt and some surface marks
     may improve, but permanent marks, wear or damage may remain.",

}

FAQ_ID FAQ_005 = {
    question: "How often should leather furniture be professionally cleaned?",

}

FAQ_ID FAQ_006 = {
    question: "How do I know if my leather sofa needs professional cleaning?",

    "Professional assessment may be useful when leather appears dull, feels
     greasy, shows visible dirt or no longer looks as fresh as it previously did.",

    confidence: 0.99
}

FAQ_ID FAQ_007 = {
    question: "Is leather cleaning the same as leather restoration?",

    answer:
    "No. Cleaning primarily addresses appropriate surface contamination.
