After each use, stretch the leather in the direction of your fingers before storing it in its fabric pouch.
To remove stains caused by wearing gloves, apply soap to a clean, damp cloth, rub and then rinse lightly with a second damp cloth. Put your gloves back on while they dry so that they retain their shape. Then feed with milk to keep your gloves supple.
For greasy stains, dry cleaning is necessary: sprinkle a generous amount of Terre de Sommières on the stain. Rub lightly and leave for several hours (overnight if possible). Then remove the soil. Repeat if necessary. For stubborn stains, take your gloves to a leather cleaning specialist.
