Badly Tarnished Brass
I have an 18th century lamp with brass parts that have oxidized so bad I can't get them clean. It belonged to my husband's family and I would love to restore the brass. The remainder of the lamp is two shades of etched colored glass that is beautiful and the entire lamp is very ornate including the brass parts which makes it extremely hard to clean unless I could find a very powerful dip.
Can anyone help? At this point the lamp might as well be trashed. Thanks,

I have experimented with a lot of brass cleaning products on really crummy oxidation. One sequence I have found to be helpful is to start out with a wet paste of
'Barkeepers Friend [on
eBay or
Amazon]' powder on an old Terry Cloth washcloth and rub the Heck out of the piece. You better have on some rubber gloves [on
eBay or
Amazon] as it eats your skin up if used for any period of time. We used to be able to find Twinkle brass & copper [affil links] which worked as the next step but haven't found it lately. We had to substitute
Wright's Copper Cream
[on
eBay or
Amazon] which I think worked
better than Twinkle actually. How you proceed from step 3 is up to you. I have tried motorized polishing bonnets with bar abrasives for polishing metal of different grits, as well as Dremel
[on
eBay or
Amazon] bonnets with
Maas metal polish [adv: Maas on
eBay or
Amazon]
, Wenol
[adv: Wenol on
eBay or
Amazon]
, etc. and they all work well. I think the
Brasso
[on
eBay or
Amazon] liquid product works OK but not as highly polished as you get maybe with MAAS metal polish. You want to thoroughly wash off any residue and spray a protective clear coating on when you are done. I am still hunting for the perfect clear coat.
