Removing burnt black soot on brass candle chain
2004
I clean many areas of the church and I'm looking for a way to get soot off a small brass chain that holds up a candle called the eternal light. It is burnt black for years of candle burning....I've tried every brass cleaner I could find out there. Remember this is black hard soot not tarnish. Thanks to anyone who may know and God's Blessings to ya.

You can use ammonium citrate solution (50 gms citric acid dissolve in 1 lit water,then add some ammonia(25%),pH must be 9!). Cold immersion(up to 8 hours). Hot solution work faster(8o C). Rinse well!
