The India-Specific Problem: Humidity Cycling
No European leather care guide addresses India's climate challenge. In Mumbai, leather expands in monsoon as it absorbs ambient humidity, then contracts when you turn on the AC — a cycle repeated hundreds of times per year. Each expansion-contraction cycle stresses the leather's surface coating. Full-grain leather with a breathable aniline finish handles this well; corrected-grain and bonded leather cracks within 3–5 years under this cycling.
