Dissolving solid copper chloride

[alex-book]

Hi All

I have a question regarding what type of chemical/solution that is recommended to dissolve solidified Copper(I) chloride around a ceramic coated sample. I know HCl and ammonia both works well with the copper(I) chloride). However, I don't want to damage the sample. I have tried EDTA but it works in a really slow manner. Any suggestion what kind of solution that could work?

Thank you all for your time and attention

Copper(I) salts tend to be stubborn but I have a recollection that acetone wasn't too bad when I tried once.
