I did this for clogged cats for my supercharged truck which had long term use of octane booster . I had the P0430 code for under threshold . I didn't heat the water but rather soaked the catted pipes in large containers for a day. They cats were clean after soaking for the entire day. I put them back on the vehicle , cleared the codes and drove it hard for about an hour to get the cats really hot. Did this is January 2019 and still good to this day.
I found the same industrial maintenance paper on cleaning catalyst back in about 2006, cleaned the converters on my car and passed emissions. PAPER; Reactivation of an aged commercial three-way catalyst by oxalic and citric acid washing Environ Sci Technol. 2006
This technique helps to clean all catalytic converters affected by contaminant and carb deposit. I did this just to see if this technique works but it ended up being permanent solution for me! The basic idea here is - These two organic acids are good solvents for catalytic converter contaminants mentioned in this video and carb deposit.

😮Anthony’s Citric Acid powder (5lbs): $18. Cheapo 12 Quart pot: $9. Savogram Wood Bleach (340ml @ 95-100% Oxalic Acid): $8. Bottled water (5gal): $7. Propane use: maybe two dollars-worth. Candle-making thermometer: borrowed for free. The formula & procedure: Caution: do this outside in a well ventilated area and wear gloves and goggles. The acid is not particularly caustic, but you don’t want to get it on stuff unnecessarily. Also, while heating it produces a smell that would not be pleasant inside-and that might indicate something unhealthy. Formula: Per gallon of water I used 75ml citric acid and 50ml Oxalic acid. Procedure: I placed the CAT in my cheapo 12 quart pot. Two and a half gallons water nearly reached the brim and completely covered the catalytic converter inside the housing. So I mixed 190ml Citric Acid and 125ml Oxalic Acid with the 2.5 gallons water. Ideal temps for the solution are said to be 150-160* F for six hours. In 2016 the tempertures were higher than recommended (185 or 190) most of the time. In 2018, I got it just right. This second time I lifted and submerged the CAT in/out of solution six times each half hour to ensure flow through the substrate
We are going to try the same, or similar process as you. Do you have a fulltext of study you are following? In newer study of same author is focused only on oxalic acid as most efficient one. I appreciate any feedback - it is more than two years you did cleaning process. Thanks

Thank you my brother for the time making this video to help others. Thank you so much!
This video was Awesome....love the research
Thank you, this video helped me a lot.

Do you have to heat it?
Thanks! Here's an alternate procedure: ua-cam.com/video/qpuWz8pWSYQ/v-deo.htmlfeature=shared
