Hi,I pulled a bunch of 12AU7A RCA Cleartops from the tone generator unit of an old Conn organ this afternoon. They all have a thin layer of grime on the glass so I took one tube and ran it under some warm water. I then wiped it with a soft rag and off came the printing. The 12AU7A didn't come off because I assume it's etched on but the orange CONN, MADE IN USA is gone. Personally I think that the orange CONN is ugly but I guess my question is, "Is there a way to clean these tubes without wiping off the printing?"
