corroded electrical wires

we just moved in to a new house. There was a pinhole leak in the copper water line that eventually corroded over and closed itself. but beneath it the gas line and electrical cords are all corroded over and rusty, as you can see in the attached picture.

The plumber who was investigating the leak said that the gas line was fine but we should probably replace the electrical. The electrician said that the electrical was fine but we should really be worried about the gas pipe.

Thought I would post this picture and see what you all think. I don't want to repost in the plumbing section, so feedback on both would be great.

We bought a fixer upper so you're going to be hearing a lot from me!

 

It looks like one big mess to me. If you didn't mark the gas pipe, I would have no clue what is what. None of it looks good. The first thing would be to fix the copper line. Just because "it closed itself" doesn't mean it's good. You could try to remove some of the rust, on the gas pipe, to evaluate it. The same for the electrical.

 

I am guessing the electric cable is the black below the copper line? As long as the sheath is continuous I would not worry about it.

 

Yes, thanks we are definitely replacing that section of water pipe. Let me try to explain what is in the picture. There are 4 wires in the front. 2 are the kind that look like they're surrounded by metal coil. Then there's one black and one whitish wire. Behind the two metal sheathed wires is the gas pipe, which is a few inches behind and you can see about half.

Should I turn off the gas before messing with removing the corrosion?

 

Actually, you might want to spray the gas pipe with soap & water. If you see any bubbles, you have a leak. Keep the spray bottle with you while you try to remove the corrosion. Use emery cloth.

 

Those are cables not wires. Wires are the individual conductors in a cable or conduit.
