Hello, thank you for your feedback. Based on this, the supplier has contacted us and would like to respond below.
"Hello, the internal surface of the oven has an enamel coating that protects it from corrosion. However, corrosion can occur if this protective layer is mechanically or otherwise damaged. Please send us photos of the inside of the oven to the email address
[email protected] so that we can assess the condition of the product."
If you need anything else, please do not hesitate to contact us. Thank you and have a nice day, Ondřej - Alza expert
