How to remove stain from copper Blocks ??

post #1 of 51
Thread Starter 
My Issue

Hi

Two weeks ago, I bought a used water block for my HD 5870, I received it today and notice some BAD stain on the block. The block is from EK and its acetal/copper..


EDIT: I tried several method, especially the KETCHUP and the best method for a complete renewal is Brasso, see below for method


Problem Solved



Steps to follow (wear latex gloves...really important)

  1. I have put the copper block in distilled water and vinegar for 10 minutes on each side. (50/50) or (75% water / 25% vinegar)
  2. Dried it (with a towel)
  3. Used brasso with a soft sponge (or clothe) to polish the block and remove all annoying stains
  4. Then I rinse it in vinegar/distilled again for 5 minutes on each side.
  5. Brushing the block in corners and screw holes with a tooth brush to remove the Brasso cleaner deposit (While still in the vinegar).
  6. After I did three rinses with only distilled water to remove vinegar deposit
  7. Dried with a linth free clothe and put the block back together


100% success..

All that combined with Blue Chemical Latex gloves that I wore the whole experience, really important to wear them not to leave fingerprints all over the block



-Vinegar
-Distilled water
-Brasso Cleaner
-Soft towel or sponge
-Latex Gloves

Metal polish (Brasso) works or wadding polish (Nevr-Dull) from auto store or Walmart maybe.

I have no experience, but if I was in your situation I would go out and buy some jewelry cleaning solution. Or anything acidic. Anything with a PH of 4 or lower would clean that well.

If you have some ketchup lying around, you can use that. Make sure it has distilled vinegar (ex: Heinz).

Also, never attempt to sand it. It will actually scratch the surface and damage the straight level milled surface. If you do use the polish, wash it in mild hot water with detergent to remove any oxides and oils from the polish after you're done.

I just tried ketchup and lemon juice and the copper is scratching a little bit, I'll go buy some brasso Copper Cleaner and give it a try. I also have to remove the stain on the side of the block, the side facing the side panel window. I dont want it to be scratched, if it get worse, I'll just leave it like this.

Clean it it with a clean cloth and Brasso. Just make sure you use a toothbrush to remove any of the dried polish and wash it properly before putting the top back on. You can remove the acetal top for a proper cleaning, as polish will creep into the cracks and crevices, so you have to clean it well afterwards.
