We recommend discontinuing use and having your cookware re-tinned only **when the tin lining has worn away and bare copper becomes clearly visible**, as copper may react with acidic foods. If you are unsure, feel free to send us a photo at us.service@ruffoni.net – we are always happy to help.

The lifespan of the tin lining varies depending on frequency of use, cooking temperatures, and the types of foods prepared. It can also be significantly shortened by improper use, such as overheating, boiling dry, or scratching the surface.  
In general, when proper use and care guidelines are followed, well-loved pans typically require re-tinning only after **10 to 20 years of home use.**
