Glass transparent lids aged badly. Indeed, despite the use of detergents "soft" (organic), passages in dishwashers print indelible marks on the glass lids. The return of products from the manufacturer confirmed that the dishwasher was at the origin of the traces, and therefore no support under the warranty or goodwill gesture from Christel. Contrary to what is advertised, these covers do not go in the dishwasher.
