Green rust may appear infrequently.
Change in color may happen when left in foods with an acid such as jam of citrus fruits.
After usage, wash and dry well. Although it is neither toxic nor harmful, it may be cleaned off following the below instructions.
Mix vinegar and salt in equal parts. Wet a cloth with the solution. Then, apply the cloth directly on the green rust and rub it off. Wash the product with a dishwashing detergent, prince it in water, and wipe off excess water with a dry cloth.
