Show in original language (French)jmvernaud10 months ago000 Helpful answerHello Janjohn, Don't use abrasive products, just clean with a little vinegar and soap, letting the liquid draw out a little before rubbing with a non-abrasive sponge. Otherwise, a slight oxidation is normal.Show in original language (French)Comment
