[GreenKeys] 33 cover cleaning

[Teletypeparts]

Hello Greenkeyers, 

I remember someone posting something about a way to clean a 33 cover, especially to remove the yellowing.  I usually use 409 which works well, but its the yellowing I am interested in improving.  

Anyone recall the process?

Thanks,

Wayne
