You're right, and you could have politely corrected my error without
rancor, but instead chose to take the low road.
Why?
Soldering 550m of copper wire

You have that effect on people!
What was in the dip?
The context was, ostensibly, that you have this mysterious substance
which was designed to be used for brackening blick and is now -
because of damage to its original container - even more mysterious and
is being sequestered in a dishwasher detergent bottle.
The premise is that you're using it for some mysterious purpose and
that the heavily tinned surface of the iron will keep it from
attacking the iron underlay.
I think most of the rest of us use a simple water-damped sponge to get
rid of the grunge, so what's the purpose of your magical mystery pour?
Its only natural you'd get confused - but you've really tangled yourself up this time!
From your myopic point of view, that's true.
I love it!

I love to cook with wine. Sometimes I even put it in the food.
I try to make some soldering pot with camping gas stove. I melted lead and soldering wire (40/60) and am guessing that final ratio is around 70 % lead 30 % tin.
Then i took copper wire mesh ( that i cleaned before ) i put this into pot. I grease it before i put it in the pot.
Well, it looks like am doing something wrong because the copper was just partly covered with lead.
Rest of it looks like it was oxidized.
What am doing wrong ?
The wire needs to be pretty clean - even for the more aggressive fluxes to work.

There are other more aggressive chemicals out there, but finding suitable ones is often more luck than judgement.
Grease?
No doubt a testimonial to your career in "electronics".
For the flux to clean the wire, the wire and the flux on it must be
heated to a high enough temperature for the oxides present on the
surface of the wire to be absorbed/dispersed by the flux _before_ the
wire goes into the solder bath.
That's about your level!
Learning by doing beats learning by rote every time.
Get some pipe acid, the stuff used to wet the pipes before soldering. it's clear and usually comes in a squirt bottle.. Dip the copper in that first.. You obviously are working with old copper.
Jamie
Is that stuff corrosive? I remember warnings in the magazines where people had used plumbing flux, only to learn it was corrosive and the wrong thing for electronic soldering.

If you've got a deep fryer you need the grease.
Michael
Very big deal.
I've seen it done. Freshly drawn wire after vacuum annealing run through a hot acid flux bath, followed by a cotton wiper, followed by a pure tin bath, then a final water-wet cotton wiper, then spooled. All at 200 feet per minute.
After a few minutes, the acid fumes get to your eyes.
The guys working in the "tinner" were all in their twenties and thirties, and looked about sixty.
An interesting place. Wherever you stood in the plant, you could see a thousand tons of copper in various forms. That was back in the day when telcos were using the stuff as fast as it was being dug out of the ground.
