How to polish a large sheet of brass?

[Bailey Guns]

I have 2 4'x6' sheets of what I think is brass that is badly tarnished. They've been behind our woodstove for years and badly need some attention. I tried Brasso and elbow grease. It works...somewhat. But I'll need a tanker full of Brasso, a truckload of rags and a lot more time and elbow grease than I have.

Any suggestions? I've looked online and have found a few that look effective for smaller items but nothing that I think will work well for what I need.

Anyone do this for a living and need a small job?

This is what the item looks like:

Do you have an electric buffer to try instead of doing it by hand?

Can be done by hand but a buffer is much faster, it works on brass, copper and bronze too.

Most auto parts stores carry it, it's about $10.00 a tub and you'll probably only need one tub per sheet.

The problem seems to be the rag or pad gets totally saturated with the nasty stuff that's coming off and within just a few minutes loses any effectiveness. I'd have to constantly change pads on a polisher/buffer.

I looked at some of the home remedy methods like the flour/vinegar but I'm not sure how I'd mix up enough to cover 48 sq ft, then dispose of what was left.

I want an easy solution, dammit! Not something where I have to put effort into it.

How deep are the scratches? That will determine your starting process.

And what kind of polish are you going for will determine your end finish.

It's broad I know, but any metal can be polished to a mirror.

Really no scratches to speak of. I just want it clean and presentable for showing the house.

Try some Simple Green.
The issue with polishing is unless it is kept constantly polished it looks like crapola.
A potential buyer may look at it as a a pain to keep up(which it would be).

If you're not set on a highly polished (mirror) finish, get some gray or white scotchbrite pads for a drill. quick, easy, and doesn't clog. White is the finest finish, should yield a bright matte finish.

Cement cleaner/acid soak, sit, the polish once the tarnish is off. Test the back so you know it works well before you soak the front.
