Leather gets dirty from our sweat and when it goes on to leather due to salt it hardens the leather causing it to crack. Also the paint from our jeans and other clothes comes out causing the colors to bond on the leather and becomes one.
Leather requires replacement of natural oils otherwise it will dry out and crack. Conditioning helps to restore these natural oils and as a result the leather stays soft and supple.
We recommend once every 60 days especially in summer, depending on the lifestyle you live and in environmental conditions.
