Remove dirt and debris from the glove leather with a soft, dry cloth. Gently wipe the outside and inside of your glove carefully, paying attention to the inner palm area and finger holes.
Fill a bowl with warm water and mild soap. Dampen the cloth with the soapy water, thoroughly wring out any excess liquid, and gently wipe the outer and inner leather of the glove with a circular motion. Keep the cloth flat to wipe the inside of your glove's thumb, finger holes and palm area.
Take a clean, soft, dry cloth and wipe away the excess moisture. Ensure you have thoroughly removed all of the moisture from the inside of the glove to prevent mold growth.
Place your glove in a cool, dry place for at least a week, if possible. Check the inner leather of your glove periodically for mold growth. If you detect any growth, gently buff it away with a soft, dry cloth.
Rub a high-quality, professional glove oil of your choice into the outer and inner leather of your glove, after it is thoroughly dry.
