How to remove stain from copper Blocks ?? - Page 5

post #41 of 51
May be shiny but ill pass on all those micro scratches. I soak my blocks in ketchup for about an hour and rinse off and it works every time for me.

Microman, I know ketchup works and vinegar also works, I'm pretty sure they do the exact same job since ketchup has vinegar in it.

I tried that before using Brasso and if you look closely at the picture below, the huge black stain beside the inlet/outlet was not going away. So I had no choice to use Brasso cleaner and I couldn't leave shinny spots where the stain were so I did the whole block, turned out pretty good IMO. And anyway, you already see the machined blade micro marks on the block left by the manufacturer

The after picture I show on the OP is before I redo the brasso cleaning, I redid it because the next day all my finger prints appeared on the block so I redid the experience with glove and that time, I polish the block in one direction only so the microscratches appear horizontaly so you don't notice, I cannot take picture because the waterblock is now on the card.

Look at this nasty stain, it did not want to go away.

Actually, Brasso didn't micro scratch the copper. I guarantee they were there and once it was polished with the Brasso, they stood out even more in the pictures. Plus the EK blocks have machining marks all over them, which are way worse than the micro scratches.

Honnestly, I think I did the micro scratches with the Brasso cleaner but like you said, its better looking than the machined marks, I like the shinny look so much. And you don't even notice them without a camera flash.

A lot of times polishing will make the surface imperfection marks show up more. Every time I polished shiny copper, it stayed shiny when cleaned with Brasso. I've done this with older socket 423 and 775 copper block air coolers. Once its polished, the shiny surface contrasts the imperfections a lot more, so you see them.

Also, when polishing, you use a circular motion, not back and forth with the cloth, if you do use Brasso.
