You should really look into the products you think work. Both Seafoam an BG-44 are mostly naphtha and kerosene. Naphtha is the solvent and kerosene is a carrier and is also there to add volume. Because you wouldn’t spend the $6-$7 dollars for the 3 ounces of naphtha that’s in a can of Seafoam.
A few points to consider. Nothing dissolves carbon. Period. You can dissolve the gunk that it sticks to, but not the carbon itself. You can achieve better results using better chemicals like PEA. The active ingredient in Techron. There is another chemical that does a good job dissolving the gunk. Alcohol, both isopropyl and ethanol. It’s a great solvent and is doing a wonderful job keeping your engine clean all ready. And, That’s the only reason why Seafoam worked at all 60 years ago. It absorbed water from gas because it contains alcohol.
If you feel you need a little extra cleaning, then add something that has been proven to work. PEA or alcohol. You can even get a can of toluene. That’s a great solvent also, and it’s used in gasoline to raise octane.
