1. Before you store your leather clothes for the season change, you must clean and polish them to give the leather "nutrition" to keep it soft, smooth and shiny, and extend its life. You can use leather polish to polish it. Dip a cloth in the polish and gently rub it on the leather clothes twice. You can also send it to a professional store for better maintenance.
2. You can use a soft dry cloth to wipe off water stains, but be careful not to use water or gasoline. If it rains, don't rub it with gasoline, because water will make the leather hard, and gasoline can evaporate the oil in the leather and cause it to crack and accelerate aging.
3. Avoid contact between leather clothes and oil, acidic and alkaline substances. When you take it off, put it in a ventilated place, but don't expose it to the sun.
4. It's best to hang it up when you store it. Cover the leather with a piece of cloth. Don't fold it to prevent wrinkles on the leather. If you put it in a box, you must spread it flat. Don't put clothes on it, but don't put mothballs.
