Seafoam = 1/3 alcohol, 1/3 Naptha (Coleman fuel), 1/3 Mineral Spirits (paint thinner/SafetyKleen).
You can look it up on the MSDS.
Mix your own, it's cheaper. Leave out the alcohol if you're trying to solve alcohol-related problems.
If you leave out the alcohol, is it 1:1 mix with Coleman fuel and mineral spirits? I think this is implied, but want to ask. I have assumed before on this kind of stuff and it didn't work out so well.
