In this video I tested Seafoam. I use a mini borescope camera to look into the engine and see how dirty the engine is before the fuel treatment and then after the fuel treatment. I followed the instructions on the container and seafoam did a great job cleaning a good amount of carbon off the piston head. I then filled the cylinder with seafoam and it cleaned out 99% of the carbon! After this test, I would recommend seafoam to clean out small engines. I am impressed by the results and finally we have proof that seafoam actually works!
