I am wondering if someone can help me figure out how to clean/remove
the (yellow mustard) anti-flux from 14k gold threaded ear posts.
To give you a little history of how I got into this situation
tonight. I was soldering 14k “threaded” ear posts into small bars of
gold and melted my first post. So I adjusted my torch so it wasn’t
as hot and brushed “anti flux” on the the threaded ear post. I don’t
know why, but he anti-flux is not coming off of the treaded area of
the post and I don’t know how to get into the treaded area clean
without damaging the actual tread. So far the only thing I’ve tried
is the ultrasonic which just cleaned the area slightly. I’m at a
loss of ideas and would love to know any tricks that might help.
Thanks in advance for your help,
