Citric Acid? To clean Catalytic Converters? For real?

[hyundaier]

The study was done in a university in Spain. An English friend of mine inAlbuquereu, gave me the report. Does anyone of you know about doing reasearch at a university any where in the world? It takes months and the data is very specific. They also had success with oaxilic acid, (don't know if I am speeling it well!)

Apparetly the process is simple:
Fill a container large enough to hold your cat with the 2:1 water to Acid ratio.
Put your CAT in the container and let sit for 8 hours. Then pick up your cat after the eight hours and flush water through it to thouroughly clean the cat of residue and citric acid and the like. Let dry. Put Cat back on car.
Apparently this will restoreit to 90% its original usefulness without harming the platinum or other metals used inside of the CAT. Is this for rreal? i mean is that actually feasible or are these guys in spain blowing smoke?
