I visited the National Film and Sound Archive in Canberra, Australia this
summer. They use an ultrasonic disc cleaner. It is quite mesmerizing to
watch the mold and residue lift from the grooves into the water dissolving
into a cloud.
Here is a link to the company the makes the sonic disc cleaners. They are
not made specifically for discs but the cleaning process works well for
them. Elma is the company that makes the machines.
They use a solvent in the water, called Cetrimide.
I have heard that with the Monks machine some buildup may look like it is
cleared but can reappear in time. The sonic disc cleaner does a fine job of
permanently removing the buildup.
