Sometimes the best way to repair a sluggish center is to repin it.

I have an old upright with perennial tight action centers.  Protek provides only  temporary relief so I want to try using H2O with alcohol. 
 
Can I apply the alcohol to the hammer flanges without removing them from the rail?  My concern is that the water/alcohol mixture will run over into onto the hammer butt or spring punching and loosen the glue.
 
Thanks,
 
David Weiss
