Leather should not be exposed to direct sunlight or consistent UV light as discolouration and fading will result. Dust regularly with a feather duster and wipe with a soft slightly damp cloth in order to prevent accumulation of dust. Dust can act as a corrosive and damage the patina of the leather. Avoid harsh chemicals and hard rubbing. Avoid sitting in the same place all the time or sofa arms. Remove, rotate and plump up loose cushions regularly. For Stubborn marks consult professional cleaners.
