A. Hi Gaurav,

I don't know what "Dechrome A" is, and do not find it in Google. But if it is HCl based, then you have added chlorides to your chrome plating solution.

Thread 56140, "Removing Chloride from Chrome Plating Solution" suggests that you may be able to remove it by dummying, probably followed by silver oxide additions. There is a lot of wisdom and experience evident in that thread, so study it carefully.

Luck & Regards,
