Thank you and that puts the idea of using that dip out the window.
But it still doesn’t answer my problem. I put a thick coating of
heated liver of sulphur on all my silver wire and sheet and jewelry
which made them black, really black. It did prevent any theft from my
shipment into Mexico but now I need to clean it off so I can make
jewelry with it. It is not a small amount to clean and using my
polishing machine is not the answer.
I looked at the suggestions you sent but none of it would clean the
serious blackening on all the silver.
Is there anything that is feasible to use?
