<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'> 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. <br>
<br>
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.<o:p></o:p></span></font></p>
