Crazy in engine piston ring cleaning ideas

[Mr_Infamous]

I can kinda see how a "piston soak" would be effective at cleaning deposits, but wouldn't it be profoundly more effective if an ultrasonic toothbrush motor (or whatever is small enough to fit) is dropped down in the solvent and allowed to vibrate the piston? Alternatively, and probably far more effective, just use a powerful electric motor to "jiggle" the crankshaft forward and backward by 0.1° or whatever would be best, at ridiculous speeds like 10kHz (or whatever would be survivable and practical within a 1kW standard residential AC power outlet limit).

Second idea is to take some super thin stranded AWM jumper cable wire, spread the strands out slightly in a cone shape so it can still fit, then push it straight down through the spark hole of a TDC piston with the top surface pre-cleaned. When it contacts the piston, the strands will fan out; stop just before they actually touch the cylinder walls. When the other end of the wire is connected to the positive battery terminal, most of the short circuit current will probably flow through the rings and carbon deposits, and it could be possible that the deposits burn like in a self cleaning oven before the battery explodes, the piston cracks, or the copper melts. Honestly, I'm only 80% joking about this idea.

The interesting thing about 'different' ideas is they can often lead towards a new discovery. Even so, done correctly, chemical cleaning is 100% effective. Take a look at 'Easy Off' oven cleaner for it's ability to clean carbon. Berryman's B12 is every bit as good in a combustion chamber. Left long enough, the parts will be spotless.

I've seen something similar to what you describe on TikTok*
It seems a variation on the method H/K dealers use with the pressurized machine/Valvoline solvent


There's also the addition of rocking the engine via the crank bolt
I've had good luck with B12/Kroil and time/gravity, but I could understand for stubborn applications/efficiency, how you'd want to speed it up
It's an interesting theory, for sure

I agree with @Cujet without a doubt. Berryman's B12 cleaned up the piston rings on my sons Kia Rio. Ran it another two years after that and it didn't burn a drop of oil.
