<DIV><FONT size=2>A test of Goose Juice (TM) for the treatment of =
verdigris
yields positive results, while treatment with Protek (TM) is less =

both initially and over time.</FONT></DIV>

<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>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.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Method:</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>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. </FONT></DIV>

<DIV><FONT size=2>Conclusion and comments:</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>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. </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Long term results are not conclusive from this
experiment. Readings should be taken again after 1 week, 1 =
month, 3
months and 6 months. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>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, </FONT> <FONT size=2>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. </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>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. </FONT></DIV>
