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. For Stubborn marks - consult professional cleaners.Use mild detergent (such as Sunlight Liquid) in warm water, applied with a soft cloth or syntheticsponge to clean the frame. Dust regularly. Clean more regularly at the coast. Do not use coarse abrasive powders, metallic scourers or silver/ brass cleaners.
