I got some lead wire, 3/16" diameter, that looks like,it has been outside for some time. It is oxidized, frosty and scaley. How can this scale be cleaned completely off? Anything I can soak the wire in? I wiped it down with a wet rag, took some rough off. I then used a piece of grey scotch bright, it took a good amount off. I can see small pitting in the surface, so I don't think the scale is completely off. For my use, I need a clean pure lead wire.

According to this http://nautarch.tamu.edu/CRL/conservationmanual/File14.htm you can use a 10% solution of HCL.

At home depot its called muriatic acid and it comes about 30% strength

Try soaking in vinegar (dilute acetic acid). Lead acetate is soluble in water.

haha, yeah, and then what? pour it out?
edit:

very nasty crap.

An aqueous solution of lead(II) acetate is the byproduct of the 50/50 mixture of hydrogen peroxide and white vinegar used in the cleaning and maintenance of stainless steel firearm suppressors (silencers) and compensators. The solution is agitated by the bubbling action of the hydrogen peroxide, and the main reaction is the dissolution of lead deposits within the suppressor by the acetic acid, which forms lead acetate. Because of its high toxicity, this chemical solution must be appropriately disposed by a chemical processing facility or hazardous materials centre. Alternatively, the solution may be reacted with sulfuric acid to precipitate nearly insoluble lead(II) sulfate. The solid may then be removed by mechanical filtration and is safer to dispose of than aqueous lead acetate.

It was also used in making of slow matches during the Middle Ages. It was made by mixing natural form of lead(II) oxide called litharge and vinegar.

Sugar of lead was a recommended agent added to linseed oil during heating to produce "boiled" linseed oil, the lead and heat acting to cause the oil to cure faster than raw linseed oil.[22]

Do not breathe or ingest the dust.

Swaging bullets?

You could just melt the lead and skim the dross.

Swaging bullets?

Yes. I found a bunch of this stuff, but if I can't find an easy way to clean off this oxidation, it's of no use to me.

I may have some muriatic acid at home, and I have vinegar. I'll try both, not at the same time of course.

The vinegar didn't do anything.

I have to ask, what's special about this lead? Given the relatively low price of buying a new spool of wire, I'd much rather shell out the cost for the new stuff instead of finding new ways to create toxic waste

Failing that, I'd melt and recast before soaking in anything. Lead melts at pretty low temperatures, nothing even close to out of range for a home shop, and casting won't leave you with a bottle of lead juice you have to find a way to get rid of

+1 to the above.

something to remember, if the wire is not pure lead, the acids may have a different effect on the material.

Unless you know it is lead, odds are it is something else.

Fuse wire, maybe, something like that. I have some somewhere in the shop, and I am pretty sure it is not pure lead. Mo idea where it ism but maybe I should look..... Maybe if I find it, I'll also find the coil of resistance wire I have been looking for.

IIRC, it has some sort of oxidation on it also.

For my use, I need 3/16" wire, and clean/pure. I can't extrude wire. I do believe I have to pass on this stuff cause I can't trust it's purity, even though I can get it cheap. And pure lead wire isn't exactly cheap, up to 5 bucks a pound, and a pound doesn't go very far.

I wouldn't give up just yet, try tumbling it in a stainless pin tumbler, or if you have access to a soda blaster Id try that too.

That said the pure lead is still worth about $1 a pound to the casting crowd.
RWS is swaging bullets into copper jackets. IF your lead is not pure and clean, then you don't get total fillout of the bullet or get voids and accuracy suffers.

It's not rolls of Plumbers lead is it?
This comes with no rosin etc cores, just solid.
I have a roll here that sounds the same.
Also used for welding sheet lead for flashing.
Max.

3/16" is no longer "wire".... it's coiled rod. If you mentioned the size previously, I missed it.

Yes, that does sound more like a form of solder or plumber's rod, etc. Definitely NOT "fuse wire".

The "wire" I have is more like 0.020" / 0.5mm. That's more like fuse wire.

Right. It's not worth messing with because the OP can sell the oxidized lead on ebay for $1/pound and put the proceeds toward buying new.
