A friend of mine had the Kirmuss "restoration" system for a year or so. I used it with him several times for records that were older and had that old book smell.
The system works. It made the older records sound a lot better. As a lab scientist and a physician, I think the seminars that Kirmuss gives are not convincing. Just no evidence for a whole lot of what he puts our there as truth. If you really followed his method, I don't think you would ever stop the cycles of scrubbing, ultrasonic bath, drying and scrubbing some more. You end up just getting tired of it, giving up and moving on to the next one. Great example of how perfect is the enemy of good.
My friend now had a DeGritter machine (like I do) and cleans a lot more records. That system works too and is ten times more convenient. Just pay attention to water changes and filter changes. The DeGritter's drying system blows air to push the water off the record. The small amount of residual fluid that you cannot see and rapidly evaporates, leaving a residue, is probably not significantly different compared to cloth wipes or vacuum suction.
