Top end engine cleaning

I'm curious if there is a safe way to clean the top end of a four stroke engine. I have quite a bit of carbon build-up on the top backsides of my intake valves and the top of the piston. I realize I can mix and additive with the fuel, but I am looking for a more quicker more aggressive option. Perhaps something I can pour into the intake manifold and spark hole, then vacuum out (if necessary) or burn off by running the engine. Seafoam has a vacuum line procedure on their website, which sparked my curiosity.

I am not aware of what you ask about. I would get some carbon cleaner fuel additive and do it the easy way. In the future always use Top-Tier fuel to help prevent this.

The old-school quick method was to pour tap water down the carburetor. The steam would quickly dislodge the carbon & blow it out the exhaust ports. I mention it only as a starting point for research--I've never had the cajones to pour water in my carb or risk the damage it could potentially cause.

I'll likely just use a cleaner additive then.
