1. Use a brush and a clean cloth to wipe the moldy area clean, then use a small amount of leather oil to evenly wipe (if the rubbing skin is uncomfortable). Before wiping, try wiping on less obvious areas of the leather jacket. If oil stains penetrate or change color, stop using immediately. After wiping, hang the clothes on a hanger in a cool and ventilated place for about 24 hours, and then use a clean cloth to wipe the surface of the leather jacket. Wipe off any remaining leather oil.
2. You can first brush off the floating dust with a brush, then use a cotton ball dipped in alcohol to clean the mold stains, or use light alkaline water to wipe, then use a dry towel to wipe it clean, put it in a cool and ventilated place to air dry, and then apply jacket oil. For leather clothing that has been stored for a long time, you can first gently wipe it with a towel dipped in 4% concentration of high-grade soap solution, then dip it in water to wipe off the soap solution until it is clean, and finally air dry.
In daily life, leather products should be stored in a dry environment and thoroughly cleaned before collection. The most effective method is vacuum isolation for storage. So there is no such thing as how to deal with moldy leather clothes.
