Hi all! Wondering if anyone has suggestions with tarnish removal in recesses of reticulated 925 and sterlium jewelry? Also I have noticed some reddish deposits building up in recesses/crevices and am thinking now it must be copper. It doesn’t seem to come off in the pickle and was not noticeable when pieces were finished.
Tried brass brush with baking soda, tumbling, aluminum foil with baking soda and boiling water and it is still there.
The way I was taught to reticulate was to do it without depletion guilding metal first. I sometimes depletion guild after with mixed results and always seem to have a few areas that go dark not white. I have had major adhesion issues with keumboo after guilding.
Other issues I may be creating is i use dawn dish soap as a replacement for ultrasonic/with ultrasonic cleaner. I use it in my tumbler too.
Also I have found a yellowing sometimes after I finish depletion guilding that I suspect could be contamination from using brass brush with water only. A finish I often use is baking soda water rubbed with brass brush.
Thanks for any feedback in advance☺
