<VV> Decarbonizing combustions chambers

[Mark Durham]

Guys, just a note of caution. Water cleans becasue of the steaming action,
and increased pressure, it lowers the temp of the air so it is more dense so
there is more power.

The cleaners use chemicals to do the job in a oil base.

I would never leave water sitting overnight in a cylinder, never. Moisture
creates acids that corrode metal. So if you do this, make sure the engine is
warm and drive it after the cleaning to get it warm enough to get all
moisture out. A few minutes idling will create more moisture and is not
enough. Go for at least a 15 minute drive on the highway.
