What do we do to the leather materials infected by fungus or mould?
In case of leather products: There are lots of anti-fungal cream available in the market. Ask any leather chemical supplier for the same. . Use a smaller quality of the cream and apply it on the leather grain surface using cotton cloth.
In case of finished leather: Use the above same method to clean the products. Also, spray the warehouse/ storage area with anti-fungal sprays.
