The leather first gets vacuumed to remove any loose debris or dirt. Next is cleaning and degreasing with a strength appropriate leather cleaner that will dissolve any solutions or substances left on and in the leather pores. If the leather is older, aged, cracked, or harder textured, we then condition it with a water & mineral based leather conditioner that rejuvenates the leather back to its original condition. The final step afterward is to coat the leather with Leather Shield, a ceramic coating specifically intended on the preservation and protection of leather while keeping the surfaces natural look and feel. 
Note: The coating WILL NOT change the look (shine/color) or feel (texture) of the leather. It will only keep it at its original condition.
