If you have exhausted all other means for solving WHY the “reduced efficiency behaviors” of your Catalytic Converter have thrown either a P0420 or P0430 Code… AND…. You want to try One Last Ditch Effort at avoiding the terrible expense and inconvenience of having to Replace the CAT… Lend an EAR to THIS information.
In Bygone years...there may have been a minor Dust-Up between “Eric The Car Guy” and “Scotty Kilmer” over whether or not is was even possible to CLEAN an Errant Catalytic Converter. It seems like common sense that pouring in various Exotic Solvents bearing HIGH VOC content and HEAT generative abilities might actually BURN OUT the left over residues coming from the Excess Unburned Hydro-Carbon Contaminants. But… nothing was ever conclusive and in many cases, making these efforts ...did more harm than good.
So… Time Passes… And if you own a Very High Mileage GMT360 (as most of them are by now...) and these P0420 and P0430 Codes raise their Ugly Heads... you might still be asking, “Is there ANY CAT Cleaner Product on the Market NOW that can actually WORK? Well… Try giving these options a chance to Rescue your CAT from “The Metal Bone Yard” and avoid having to perform this expensive CAT R&R:

And HERE is an Alternative Technique Video and Product to perform an Effective CAT Cleaning:
Finally… THIS would be my choice ($120.00) for a Very Versatile, Adjustable Pneumatic Fluid Pressurization Tool Kit that can also be used in MANY other ways such as for De-Carbonizing Piston Heads, Valve Seats and Impacted Compression Rings (ALL Causes of Clogged CATs and Gummed Up Lower Engine Crankcases) as well as for EFI Chemical Cleaning under Pressure and of course in THIS Case ...for Cleaning Out CATs with a variety of Chemical CAT Cleaners of Your Choice… Thusly:
