We have a whirlpool in our basement and the copper is getting covered with a
green,semi-powdery coating. I have tried several cleaners and even
electrical cleaner, but this stuff is stubbornly staying in place. Anybody
know of a way to clean this off without scraping? Thanks.

You're going to have to polish it off. I'm assuming what you're
describing is actually just oxidized copper.

You didn't specify WHICH copper was turning green, so I'll assume you mean
the pipes leading to the whirlpool. Here's an explanation of the green
color:
"Copper exposed to water, oxygen, and CO2 in the air form a complex mixture
of oxides and carbonates, referred to as "patina". The presence of acids
accelerates the process."Basically, it's copper's version of rust. No need
to obsess about it. But, copper wasn't the best choice for the pipes which
are close to the whirlpool. PVC (plastic) would've been better.

Nowhere near the whirlpool. They are in the next room.

No need to be obsessed about it, but makes it difficult to sell the house
for a good price. Grey poly is running to the whirlpool. These are in the
next room and are the main lines running up to a manifold to run individual
poly lines to each sink/faucet/etc.

I mentioned "adjacent" because any of the factors can accelerate the
oxidation. If the area around the pipes is damp at all, you're going to get
the green stuff. Has anyone looked at the house and actually commented on
it? Customer? Realtor? If yes, get to a hardware store and pick up one of
the paste-type products made for cleaning the green away. But, if you don't
find the cause, it's going to return.
