Has anyone tried this stuff? At least at amazon, about half
the reviews indicate it worked.–

If it needs cleaning, then something else is wrong with the engine
which requires addressing/ correction first. CATs are designed to
operate at stoichiometry and any other A:F ratio mixture will kill
them sooner, or later.
The original CAT(s) would probably last forever if the XK engine
wasn’t mapped ever so slightly fat. The aftermarket CATs last
about 2 seasons at peak performance and then trail to failure in 5
years or so (due to thinner platinum coating on the substrate).–

I can’t imagine anything that would ‘clean’ a cat. They are kinda
like a stack of straws, with the gases going through them down the
pipe. They only get ‘dirty’ when the engine is burning oil, running
rich as previously mentioned, or if they get plugged with bits of
slag and generic crud from the upstream exhaust system. You can’t
really ‘clean’ the cats from the slag and crud, but if you get the
chemicals in the fuel to somehow clean the front cat, you will have
a heckuva time getting the rear one clean. The gases are cooler by
the time they get to the rear one, and I can only imagine the
cleaner would need some heat to work.–

That might depend on the definition of ‘work’, Dan…
It may certainly ‘unclog’ a cat converter - restoring passage of
exhaust. But I seriously doubt it will restore the converter to its
emission cleaning capabilities…
