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 the 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. Wipe frame with a cotton cloth. In case of spills, wipe immediately with a clean absorbent sponge or cloth.
