Chrome Plating Chloride Contamination: Smart Recovery Tips

Summary for chrome plating chloride contamination Discussion

Accidentally put dechrome in chrome plating tank is the core problem in this thread: Gaurav Sharma says a Dechrome A solution was mistakenly added to a chrome bath used for rotogravure cylinders, after which the parts developed side white and a hatched appearance in the chrome bath. The reply notes that the exact chemistry of "Dechrome A" is unknown, but if it is HCl-based, the likely issue is chloride contamination in the chrome plating solution. The answerer recommends studying Thread 56140 on removing chloride from chrome plating solution, where the suggested recovery approach is dummying, probably followed by silver oxide additions. The response is cautious and does not claim a guaranteed fix, but points to chloride removal as the most relevant corrective path and emphasizes that the referenced thread contains substantial practical wisdom.
