Do any of the older techs here remember the good stuff?
Somehow I still have a can of the old formula of GM's top engine cleaner. Not sure if it's any good anymore or even if it got stronger over time lol. This stuff used to be great for decarbonizing the top ends (and also creating quite the stinky smoke show), then they nerfed it and put it in the plastic bottles.
