This is what I'm talking about.

Ok I agree, but I'd say what I did was actually more beneficial to that valve than just spraying one can into a throttle body and hoping it directly hits every single valve on an engine. Never mind the amount that flies right past the valve into the cylinder and out the exhaust...or the amount that sticks to the manifold.
I sprayed an entire can directly onto the valve. Then I added a bottle of intake/engine cleaner...let it soak for four hours. I rapidly moved the valve back and forth in that solution every half hour. Then I took the valve out and heated it with a torch (while the solution was on the valve). Then I put the valve back into the solution for another hour. Then I took the valve out and sprayed another can onto it. Almost no carbon came off. A few specs here and there.
I agree it's not engine simulation, but I more than reached engine temps to that valve. I saturated that valve much more than any valve would have gotten with a can or two induced into an intake manifold.
I've seen that video before, I've also seen others where there is minimal (at best) removal of carbon from various products. I would venture to bet water would work just as good. I'd also venture to guess that if you boroscoped an engine...before and after...without adding anything at all...you'd also see "something". Something would happen. Moisture from the PCV valve...engine heat...rapid up and down movement of the valve...turbulence of air passing the seat/stem of the valve. I'd venture that you would see some sort of change/improvement, until the valve cokes again.
I think every one of these companies that sell carbon cleaning solutions should be required to pull the manifold, take video and pictures of the valves (before)...put the manifold back on, run their solution through and then remove the manifold and show the results. There is absolutely no reason why they shouldn't be required to show this. Maybe some do? I haven't seen it. I've seen some before and after photos...probably of one port (either right by the PCV or directly in front of the throttle body). Show the whole story...one run with one can. Video evidence. One can.
Are you suggesting the Illuminati is behind some deep state like IVD cleaner conspiracy??...¨...‚
Have you thought about calling GM and telling them their Delco Top Engine spray cleaner (that is literally specd in GM TSB's) is BS?...While you're at it, call Chevron, Gumout and CRC Ind. and let us know what they say in re to your thoughts...oh and call Valvoline too while you're at it because they mfg a spray in IVD cleaners too.
Yes, my goal is they'll have to pay me enough money to keep me quiet...or I'll end up in a ditch. Netflix will probably make a new "original" film about it...they'll call it "Selling Fear, carbon cleaning conspiracies".
But you're really on to something about the GM TSB. Yeah GM has never failed at one of those. Bawahaha. I remember their "remedy" for their noisy intermediate shafts...inject the shaft, then stroke it fifteen times. Yeah, that worked like a charm. We all looked like we were giving hand jobs to steering systems. Never did get rid of that noise...well it may have gotten a few out of the warranty period. Good old GM.
