I spent part of the pendok soaking in citric acid during a whole afternoon, after rinsing well, rubbing with a cloth and then drying the color is indeed much more silvery but still with a touch of yellow.
At one place there was a black oxide crust which has now become the same color as pure copper. ![]() Quote:
