Sarah,

Your experience seems to be completely the opposite of those of us 
who have used the alc/H2O treatment quite successfully. The alcohol 
is a surfactant, allowing the wool cloth to soak of the water. Water 
laden, the bushings now squeeze against the center pins, and during 
the 24 hours (roughly rumored thereabouts) is takes the water to 
evaporate, the wool fibers take a compression set around the pins. 
Once the bushings have dried out this compression set will have 
produced a looser fit.

Granted it won't work on bushings contaminated by paraffin oil or 
WD-40, or rusted pins. But those situations are the extreme (except 
of course for an entire era of Steinway), and are easily spotted.

Time is an unavoidable ingredient in this process. Simply soaking the 
bushing and immediately thereafter chase it out with a hairdryer 
won't allow the compression set to occur. Tommy should confirm that 
this action is not suffering from one of the exceptions, then pick up 
pick it up some morning, apply the alc/H20, and bring it back the 
next morning.
