[Jewelry making - Article 00219] - [Orchid] Removing borax/boric acid/alcohol mixture

    I need help with a terribly stubborn black coating on a fancy
    sterling silver ring that remained after I used the borax/boric
    acid/alcohol mixture described in Mr. Lewton-Brain's article here: 

    http://www.ganoksin.com/borisat/nenam/firescal.htm 

    I followed the directions exactly but it doesn't say how to remove
    this coating. The ring has all these inaccessible parts (which is why
    I was trying to protect the high polish before assembling for one
    final soldering) and brass brushing won't remove the black coating
    from these areas. Brass brushing hasn't even removed it from the
    *accessible* areas. I don't have an ultrasonic cleaner but if someone
    out there knows that that will remove this stuff for sure, I will buy
    one. 

Thank you all in advance for you advice.
Jessica
