Aduro wood burning stoves have been painted with a heat-resistant spray paint that does not rust when the stove is properly stored and installed. If your stove rusts, it has been exposed to moisture from either condensation in the chimney, cleaning with water, moist air, moist wood or lack of use during the whole year.
PLEASE NOTICE: It is important not only to repair, but to find the cause of the problem and solve it. If not, the rust will return.
