Have any of you ever used Wenol metal cleaner / polish? I have used all kinds of stuff but never this. Due to my current restoration project, I was urged to try this to clean heavily tarnished brass. I am restoring a brass bell that came off of a Southern Railroad Steam Engine #440 which was a Baldwin 2-8-0, manufactured around 1900-1903. I acquired the bell from the gentleman that got it when this engine was being scrapped in 1950. So, I've got over 100 years of tarnish to remove and am looking any advice from anyone that may have experience polishing brass. I have used Flitz on other items, tried it on this, along with Brasso but still have a lot of work to do. The Flitz has done ok, but............ still got a lot of polishing to do.
