Do you have any idea why the researchers never did anything with the idea?
I would interview a couple of muffler shop installers to see how many cats they've remove that are candidates for cleaning/rejuvenation treatment. You know, look physically good (the ceramic isn't broken, case not rusted through) but aren't working as advertised.
Another thing to consider with such a cleaning system in a commercial application is the waste stream... concentrated heavy metals, oil, etc in high Ph water solution might be difficult/expensive to dispose of in California. There has to be a way to post-treat on site, but it might be expensive.

Not sure why it wasn't put into play...or anyone else picked up the ball. Doesn't matter to me...I'm having fun!
Baking soda will easily neutralize the weak acids in the residue solution.
There isn't an incentive from the shops' point of view as they will lose money fer cleaning yer converter vs replacing it. They do make some money on the parts (parts markup %) as well as the labor fer removing the old and installing the new. They also make some money fer recycling the old part. No shop would throw money out the window fer a cleaning process compared to what they earn fer remove/replace. If they did, they be a fool.
This process is more fer the DIY'er who might have an option to save money compared to a costly replacement. With the exception of the cost of the wiring (switches, box, cord and plug) and the chemicals, everything else I've put into this CatWasher were scrap materials.
