Conditioning- recommend a preventative maintenance routine three to four times a year, once prior to the winter season to prevent cold temperatures cracking the leather, and once before the heat of the summer to prevent deterioration and shrinkage by heat, which result in continued cracking of leather. In addition to regular cleaning, leather requires replacement of natural oils; Collagen-based products restore the lost moisture and maintain it's natural flexibility. The smell of leather comes from oils evaporating out of the hide.
Schedule: Once every 30-60 days, Arizona, Florida and Texas, especially in summer, for northern climates between 90-120 days, use a leather conditioner to restore these natural oils and keep the leather soft and supple. (Criot's Leather Care, Autoglym Leather Care Cream, Zanio Z10 Leather in a Bottle or Zymol Treat leather cleaners are all good maintenance products)
It is possible to over-condition or over-clean your leather as this may lead to premature cracking and discoloration. Most leathers are treated at the tannery with a protective coating to help protect against staining. Excessive cleaning and conditioning can remove some of the protective properties. Carry a small spray bottle of water and a clean micro fibre cloth so if you ever spill something onto your leather, spray the affected area and wipe it as soon as possible, you should then treat the affected area with leather conditioner.
