Wash it gently and dry the glass with microfiber swab, do not use chemicals. You can wax it with a proper material such as car wax for a more shiny and new look. But, note that some waxes may remove the patina so please try it first on an unseen area to see the result and then apply.
Do not scratch the soldered parts as this may cause harm to the patina.
Please note that patina acid may react with air on different humidity levels so if you notice a color change; first, don’t get worried. Just wax the object with a proper material just like car wax that you can purchase from any store.
