Pepsi Pinblock Dope?

[justpianos@our.net.au]

Recently called to a school hall Yamaha U1. Very tubby/dead bass end.
Apparently partial cup of coffee accidently fell into open top of piano.
On inspection I found sticky bass strings, pinplank and soundboard.
After carefully washing appropriate areas, including strings, and allowing to 
thoroughly dry, I was able to wind an extra 2 turns on about 2 octaves of 
bass strings, which totally improved the overall tonality.
The school had already obtained a quote on a full set of replacement bass 
strings, and so were amazed at the reasonable price to greatly improve the 
piano.
I don't doubt that they will need a bass restring in the future but the 
school will probably dispose of the piano before this.
