Hi everyone. I need some advice on how to remove oxidation from heatsink. I have tried using a diluted vinegar with distilled water 1:4, soaked it for about an hour. After general brushing and rinsing thoroughly, I still find the oxidation all over the place, and it is rather painful to be using a knife to be scraping them off. Attached are the pictures of the condition (after cleaning with method mentioned above). Before anyone tries to suggest, this GPU is a generic Nvidia P104-100, so I cannot find a replacement heatsink. I would greatly appreciate if anyone has other solutions or suggestions to offer. Thanks.

Try to soak it in Coke for hours. I know it works for copper, but not sure about alu.

I have read somewhere that from chemistry standpoint, Coke works for copper but not for aluminium. Nonetheless, will give it a try, thanks. If anyone else have some ideas, please feel free to continue pouring them in.

I think most 1060 have the same mounting.

Hmm, I tried googling a few 1060s as u mentioned, but could not seem to find any that would be suitable. https://www.bitnand.com/product-page/nvidia...100-mining-cardThis is how the card looks like. If u do know of any heatsinks that can be compatible, please share. Thanks.

Thanks for the info anyways.

Thanks for input! Anyone else have chemical type cleaning suggestions, please keep them pouring in, thanks!
