My front door has a "Faultless Lexington Handleset with Ball in Polished Brass" (http://www.homedepot.com/p/Faultless-Lexington-Handleset-with-Ball-in-Polished-Brass-HY7731B-F/203187008). As you can see it's all tarnished. At Home Depot it's $60 to get a new one, but I don't want to re-key. Is there something I can use that could bring it back to life without having to spend hours cleaning it? and is the only way to clean it well to take if off the door? I'm just trying to make it look good, not perfect. Your help is much appreciated!
