Hi David,
I  was just thinking of calling to ask how things were going.=20
The product that you tested was not Goose Juice but Goose Juice+
The + is Ballistol.  Samual Lewis is also doing beta testing on Goose =
Juice+
The blend you and Samual are testing  is  one part Ballistol to two =
parts Goose Juice.
Your tests confirm my findings. There is one other thing that either =
straight GJ or GJ+ will not do and that is turn green with a reaction to =
the brass. Try placing a piece of brass in the oiler for a week or month =
to see if there is a reaction.
Thank you for your work in beta testing, it is much appreciated.

  A Comparison of Treatments for Verdigris

  Abstract:

  A test of Goose Juice (TM) for the treatment of verdigris yields =
positive results, while treatment with Protek (TM) is less effective =
both initially and over time.

  Materials:

  1925 Steinway A action with severe verdigris in wippen flanges.  Goose =
Juice (TM) provided by Joe Goss of Mother Goose Tools, and Protek (TM) =
for comparison.

  Method:

  Eight flanges were measured prior to treatment with a Neuses 10g =
resistance gauge.   All flanges exhibited characteristic green color =
around center pins.  Five (1 - 5) were treated with Goose Juice (TM), =
and three (6 - 8) were treated with Protek (TM).  Lubricants were =
applied to inside and outside of each side of the flange and the flanges =
were then rotated back and forth 20 times each .  Flanges were left to =
sit for 30 minutes and measured again.  Flanges were then allowed to sit =
for 24 hours and measured once again.   Flanges were measured again =
after 48 hours.  =20

  Results:

  Flanges  1-5 (Goose Juice (TM))

  #            Before treatment       30 minutes        24 hours        =

               7                        9

              7                        8

  Note:  Maximum gauge reading was 10g.  Any reading exceeding the =
maximum was registered above as 10+.


  Conclusion and comments:

  Goose Juice (TM) was effective in reducing the effects of verdigris =
significantly more than Protek (TM) on these samples.  Moreover, Goose =
Juice (TM) demonstrated a more lasting effect.  At this writing, it has =
been about 72 hours since the treatment was initiated.  Flanges 1 - 5 =
are still holding at the 48 hour reading.  Flanges 6 and 7 have remained =
at the 48 hour reading.  Flange # 8 has increased to 9g. =20

  Long term results are not conclusive from this experiment.  Readings =
should be taken again after 1 week, 1 month, 3 months and 6 months.  =20

  Note on application.  Goose Juice (TM) is a more viscous solution than =
Protek (TM) and thus it is not clear to what extent it penetrates all =
the way through the bushing.  Whereas it is easily observable how Protek =
(TM) is easily absorbed by the bushing and surrounding wood,  Goose =
Juice (TM) appears to sit on the surface for much longer and doesn't =
penetrate quite so readily.  Nevertheless, it does appear effective in =
its treatment and it can be assumed that absorption does take place.  It =
would be interesting to see whether modifying the composition of the =
solution so that it contained either a penetrating carrier, or a higher =
percentage of penetrating carrier, would effect the results. =20

  Based on these results, it appears that Goose Juice (TM) is at least =
an effective temporary treatment for verdigris, and possibly an =
effective long term solution.  An attempt to duplicate this data should =
be made. =20
