PEA needs heat to activate, that's what makes it superior to other solvents that can't survive the combustion chamber temps (even before compression) long enough to do anything.
Berrymans, it has a very stout mix of solvents...way better than Seafoam. A gentler mix would be MMO. There's a line of thinking that says it's better to de-carbon the piston tops in little steps to avoid a big chunk breaking off and getting stuck between the exhaust valve and the seat. MMO is a mild cleaner..I think it's mostly a kerosene carrier with mineral spirits and some other stuff in small amounts. Kerosene btw is a mild solvent too. I've used it to remove grease.
I would not use a PEA based cleaner, it's a waste of money for what you're doing. Xylene, naptha, toluene, mineral spirits, kerosene are all good solvents and readily available .
