You can count on it.

I share your concern re applying alcohol/water to CFIII hammers. The 
earlier CF pianos had 'concrete' hammers which could justify such 
drastic measures if the hammers weren't being replaced altogether. 
But the latest CF hammers use Wurzen felt. The proposed treatment 
will ruin them. If you are having a difficult time it might be worth 
warning the University what will happen to the hammers should this 
'treatment' proceed.

You may have to just sit back and let the disaster happen, but at 
least if you pre-warn the department, they won't be able to say they 
weren't told. Besides, your sage-advice will probably get you the new 
hammer hanging job.

Best regards,
