alcoholic key cracks

[Porritt, David]

Tom:

 

I've used isopropyl on keys many times for many years and have never
seen any cracks or other problems.  I can't imagine that the alcohol did
it.  Is it possible that the keys were already cracked but the cracks
were not apparent until the alcohol cleaned them?

List

 

 A client of mine just bought a Yamaha G3 from a private party.   She
decided to clean the keys real good, you know, disinfect them and all,
so she used alcohol and rubbed them clean.  Later that day she found
little hairline cracks on 18 of the keys.  

I've never heard of this before.  I've never tried (nor recommended)
alcohol on plastic keytops, but evidently this is a pretty bad choice.
I always recommend Windex, sprayed on a cloth not on the keys
themselves.

 

Still, I wonder why only 18 of them cracked?  

 

Has anyone else ever heard of alcohol causing cracks in plastic keytops?
