I know there are several types of copper classified by scrap yards and the industry in general. What if I came across a used appliance that had come to the end of its life and extracted the copper from it and it had debris on it that couldn't be easily wiped off to improve its appearance/value. Would I be be able to improve its value if I used a wire brush or a grinding wheel to remove said debris?
If it's still insulated then it wouldn't matter to the yard. Save your time and energy and apply it somewhere for better $
Most yards grade copper by size, also insulated and non-insulated.
I should have been more specific. If I came across the copper tubing leading out of a water heater (non-insulated) and I ground the debris off it, the result would still be the same?
They'll take it as clean #2.Quote:

I don't think they'll give you #1 for copper tubing.
Mine does as long as there is no solder or paint.Quote:

Hope this helps!
I just cut off the dirty parts and separate it. #1 Clean, #2 Dirty
Is it worth the time and effort to clean it?...Not to me.
