The problem with brass is it is often made with a sealer on it and even the bras so won't help. I love the patina of brass as it ages ...but with a sealer on it sometimes looks crummyI meant to say they use Ketchup without damaging them
My Grandfather was a collector
Put some Ketchup on a rag and I wipe it on my Brass and Copper mods and they look brand new again![]()
