Reduction of Gold Plating Usage: Serious Surface Problem

Summary for reduction of gold plating usage Discussion

The focus keyphrase, reduction of gold plating usage, is really about a process problem after trying to save gold by cutting it with tungsten. Goon Phaik Yoke says the gold surface became carbonated after cutting and asks how to remove the contamination, specifically whether Butyl Cellusolve, methyl ethyl ketone, or sodium metasilicate would work. The excerpt does not include any replies, so there is no confirmed solution or consensus in the thread text provided. The practical takeaway is that the issue is a post-cutting surface contamination problem, but the source excerpt alone does not establish which cleaner or treatment is effective. Any recommendation would need to come from the missing answers or further technical evaluation of the carbonized layer and the cutting process.
