After a couple years’ of use, the leather in your car or sofa can crack and rip if it hasn’t been properly cared for. It’s amazing how quickly leather can go from looking luxurious and expensive to looking brittle and cracked. Wear and poor maintenance are the main culprits of damaged leather, caused by body oil. The leather becomes darkened where the body oil has penetrated, creating cracking and brittleness. When the piece hasn’t been cleaned and maintained regularly and the damage has set in, then the leather will not be able to be renovated or redyed without first removing the damaged area and replacing it with a new piece of leather that matches the existing leather.
