Does all leather crack?
Full Grain Leather is the best quality leather you can buy and if it is looked after it will last a lifetime but if its natural oils are allowed to dry out it will be susceptible to cracking. If Full Grain Leather is soaked in water, it will lose its natural oils and when it dries out it will crack. Applying conditioner to the wet leather allows it to seep into the pores left open by the evaporating water, replacing the oils and lubricating the leather.
Exposing Full Grain Leather to hot sun will also dry out the natural oils and once again, conditioner should be applied to rectify the situation. Full Grain leather is the most durable leather, however Top Grain Leather often has a semi aniline dye applied which provides it with a thin protective coating which reduces the possibility of cracking, although over time this protective coating will disappear and the leather will need protecting with conditioner .

Even with careful treatment, bonded leather will peel and crack as it dries out over time and even the regular application of conditioner will not prevent this.
How to clean leather and prevent cracking
Before attempting any leather cleaning or conditioning you should always test on an unseen area of the article to ensure that the treatment will not adversely affect the dye.

Never apply too much conditioner, this will clog the fibres and cause them to rot.
