When handling the platinum crucible, potassium thiocyanate was mistakenly used instead of potassium pyrosulfate

The inner surface of the platinum crucible has turned black; how can it be removed and treated? Thank you
I’d like to know that too! What is the use of potassium thiocyanate?
Chemical industry folks, how should this be handled? Thanks
It’s best to analyze this. Platinum crucibles cannot be used to melt substances containing sulfur; it’s possible that a black substance called platinum sulfide is formed as a result of the reaction, and this substance may be difficult to remove. If it’s just carbon deposition, then it’s easier to deal with
