Occasionallybrass door handles can begin to look a bit dark and tainted after 1 or 2 years exposed to the elements. Some handle sets are brass and some are just brass plated so you’ve got to make sure you know what you are working with. The reason why we do this is because brass plated handles should be cleaned with abrasive materials. You do not want to take the likelihood that you can scrape the brass right off so you want to utilize a more light solution. The simplest way to discover is to utilise a magnet on the handle.
