Leather is a natural material. Like most natural materials, it does need some care to ensure a long-lasting life.
You can remove light stains by carefully wiping with a damp cloth on the stain. To maintain the quality and shape of your leather clothes it is important to prevent the leather from getting too wet. Should this happen, allow the leather to air dry in room temperature. Never use a tumble dryer or a hairdryer as the high temperature will dry out the leather.
When storing leather clothes make sure to keep away from the sun as the direct and constant sun exposure will lighten the leather.
Keep your leather clothes in good condition and prolong its life by softening the leather with leather conditioner or leather grease when needed. Never use detergents, ammonia, oils, polish, varnish, etc. as it will dry out and damaged the natural moist of the leather.
