P3D Brass, again, for antique viewers

[Bob Wier <wier@xxxxxxxxxxxxxxxxx>]

Here's something from another list I'm on - this is rather
surprising as the first item is the same as the formula to CAUSE
tarnish on new brass parts, which was verified here as being effective.
I guess it all depends on whether the part is immersed or suspended
above in the vapor (!).

        From "The Weekend Refinisher" by Bruce Johnson:

        1 part household ammonia
combine ingredients is a glass container. Insert item, let soak, then
remove and rub with cloth and clean.  Seal with paste wax or lacquer.

Brass Cleaner (for tarnish)

        vinegar
        salt

lacquer.

        lemon slice
        salt

        -----------

I tried the first and second formulae.  The second was a pain in the neck
and didn't seem very effective.  The first was pretty effective.  I used
it on a brass chandelier that was almost black.  I disassembled and let
all parts soak a good while (be sure to completely immerse the item).
Things looked a lot better coming out of the solution, but still required
one go around with Brasso.  I'd probably still be polishing if I had only
used Brasso.

        Johnson has a section of various formulae (including those above)
prefaced with a warning to test on an inconspicuous spot, use appropriate
ventilation, wear appropriate safety gear, etc.

Thanks,
Bill Coulter
