Years ago I had several chance to compare Sea-Foam with a General Motors product called Top Engine Cleaner. If I recall, they smell somewhat the same. When I had heads off of an engine, I would put SeaFoam on top of several pistons, and TopEngine cleaner on others. The Top engine cleaner would make very short work of the carbon, the Seafoam would barely touch it. The SeaFoam salesman ( who came on like a snake oil salesman in an old western) said it was because heat was needed for the SeaFoam to work.
Back in the 70's and 80's we used Top Enging Cleaner to clean injectors at the Gm dealerships, before they came out with a real injector cleaner, mix it 10:1 gas/TopEngine, pressurize and run system. Also used it to loosen stuck oil rings, good stuff. Read the warning label on can, way bad stuff to inhale. I wear a reserator when I use it (still use it a couple times a month for something).
ALthough I really have no way of knowing, I suspect that SeaFoam is basicly the same stuff as TopEngine Cleaner, although in a weaker concentration.
Top Engine Cleaner available at most GM dealerships. READ THE LABEL!!
