Selective Etch for Silver Solder on Stainless Steel


(2000)

I am trying to remove an excess amount of silver solder from a thin stainless steel part without etching the steel. Components of the solder are Ag(45%), Cu(15%), Zn(16%), Cd(24%). The amount to be removed is only a few 10's of microns. Either an etchant recipe or a commercial etch product would be acceptable.

Are you removing the excess from the edge of the solder joint? Will you want to apply the etch using a brush to the area you want to tidy up? Regards, Tom

I have a Ford Model A stainless steel windshield stanchion that has several 1/4 x 20 holes that have been filled with silver solder (composition unknown, and what year done also unknown). Can silver solder be removed with nitric acid without damage to the stainless? If not what method can be utilized for this removal?
