Clean, condition and seal your pants as soon as you bring them home. Wipe the pants down with a damp cloth, apply the conditioner recommended by the shop where you bought the pants and then apply a sealant to prevent water damage.
Clean your pants with a sponge, warm (not hot) water and mild soap, particularly if perspiration or other buildup is on your pants.
Let your pants air-dry naturally -- don't apply heat to dry them.
Store your pants by hanging them, draped once over a thick, wooden rung coat hanger rod, according to Leather Supreme. If you are storing them in a drawer, loosely roll them up -- don't fold them.
