hi just try leaving the gloves off till it goes as you have not said what there made of its makes it very hard to give advice but try giving the a real good wash with lots of clean water after if its a leather or leather type material could be something that's been in the tanning of it so good wash and rinse when dry try some leather oil on it like neats-foot-oil its used to keep old leather supple. do hope this helps you. good luck
