Tarnished copper, what to do?

[Illah]

I know there's that stuff (CLR?) that clears off tarnish off copper. What is it? I just got some new waterblocks but the copper still looks kinda raw, it needs some cleaning. Don't tell me to just lap it cuz the tarnish is everywhere, not just the bottom. Thanks!

the base of my v7+ is a bit tarnished too. does using any type of cleaner wud affect its thermal performance?

[BaThMaN]

you could use a rubbing compound (the one used in automotive paint)... It works great for me... just a few buff and voila, looks good as new!!!

[spazzkid]

but rubbing compound is oil based. im afraid it might hinder thermal performance. hmmm..

you could use brasso.

just make sure that whatever you use, if you use it on the base to give it a thorough cleaning with alcohol or something similar afterwards.

Like Looktall recommends I use Brasso and then after that a good dose of alcohol. Brasso works great and will give you a nice shine. While you got it out go ahead and lap it. Its easy to do just takes time and a little 800 grit wet/dry sand paper. After you lap it hit the bottom with the brasso/alcohol again and you can shave in the reflection.

If memory serves me, I think you can mix salt and vinegar to make a copper cleaning solution. That is what we used in grade school to clean pennies (and I'm 40 now so that was a long long time ago). Hope this helps. ST?

[looktall]

yep.
i've used that on brass, i don't see why it wouldn't work on copper.

IIRC you mix it up so it is like a paste. you rub it on, rub it in a bit then wipe (or wash?) it off.

[SeedTick?]

I don't think it takes much salt. What I done was take a small glass bowl and cover the bottom with salt and then put in enough vinegar to easily cover coins. Then I just soaked or dipped the coins in the solution. It is the chemical reaction that removes the tarnish. ST?

[looktall]

ok. maybe it's different for copper?
when i did it, it was for brass. (candle holders and bowls etc)

Salt and vinegar sounds good, seeing as it's free :) Thanks guys.
