Lol the amount of guys on here that think they are chemists never ceases to amaze me! You think because you read the MSDS sheet that you know exactly what is in SeaFoam??? C'mon guys there are proprietary ingredients that are NEVER listed in detail on an MSDS, To easy for someone to copy! So yes, the MSDS says alcohol and kerosene, but I'd bet you a paycheck that is not the ONLY things in it and certainly NOT the ACTIVE ingredients!
Seafoam has its purpose and it does work, there have been too many tests and testimonies for me to believe otherwise. I use it in OPE and many other things with great luck, I've also found B-12 to work just as good but cheaper.
