A few points:

All combustion creates H2O and CO2
H2O and CO2 combine to create carbonic acid
Carbonic acid is weak acid rain; always been around, always will.

Impurities in combustion creates problems
Nitrogen leads to nitric acid
Sulfer leads to sulfuric acid
Now THAT is the good stuff!

Unbranched carbon chains lead to incomplete combustion
2,2,4 trimethylpentane is GOLD to refineries ($300.00/gal)
Ethanol burns nearly completely in just the atmosphere

Aluminum is one of the most reactive metals; more so than iron
If you scratch a piece of foil, the oxide is formed before you finish scratching!


The alcohol in the water bath will actually prevent any corrosion form forming by delaying the oxygen from reaching the metal. Most guys keep their razors in vodka to keep them sharper longer.

The concern of oxidation comes from the reaction intermediates mixing with the nitric oxides in addition to the ample kinetic energy.

The best way to test any part of this equation is to try it in equal motors.
