How to Clean Zalman CNPS7000A-Cu Copper Plate Tarnished

Post by villa_joe » Sat Jul 10, 2004 10:53 am

I recently bought a Zalman CNPS7000A-Cu to go with my Athlong 64 3200. I noted right before placing the Zalman on the CPU that it is very tarnished. This is probably from my fingers. Does anyone know what I can use to clean this surface? I started to use an everyday brass polish, but was afraid of a possible chemical reaction when combined with the T44 HeatSink Compound on the processor.

don't think you're supposed to use polish. try isopropyl alcohol or acetone.

Actually vinegar is really good for removing tarnish from copper. Just boil the heatsink in a vinegar/water solution for a couple hours.

(obviously that requires removing it from the CPU and removing the fan :wink: )

I visited in a forum with tech support guy from Zalman today. He told me to use a brass polish and then remove the residue with Alcohol and soft cloth.

I with I had read your replies first, it would have been a whole lot cheaper.

I have heard ketchup works for oxidation and discoloration on copper

And the main ingredient is ketchup is..... :wink: It's the acid that does it, it pulls the copper oxide into solution.

All sorts o' food would work...

Coca Cola probably would work, too. It has been used as a rust remover -- it also has an acid...

I just ended up using some brass cleaner and then wiped everything off real well using some alcohol.

Per recommendation from the tech at Zalman.
