Like turning copper pipe that has corrosion into bright and shiny pipe. ANyone do this? If so... what are the methods? I want to maximize my profits. I have a lot of stockpiled pipe that would be considered class 2 instead of class one.

Also... what about processing scrap or disguising it so that it is taken?

Example.... my workplace replaced their antiquated system with an ethernet phone system and they threw out a large bundle of old telephone wires.

Well, every scrap metal recycler around me refuses to take telephone wires. So i figure that I could do either of the following... Wrapping other wires around telephone wire to hide it, or stripping all the wire of insulation so it is just bare/bright very thin solid copper wire and intermix it with other thin copper wire.

Is this generally frowned upon?
