Oxidation
 

My engine has some oxidation on it and i was wondering wat is the best way to remove it

thanx

FLITZ IT!! kidding...i dont really know i just had to say that :D

More detail please. Where is the rust and are you sure that is what it is.

Aluminum does not rust, but steel does. If you have rust on the aluminum areas, then it probably came from somewhere else unde the hood.

Generally speaking if you are talking about iron-oxide (rust) citric acid will dissolve it very easily and it is pretty easy on the metal. Hydro-chloric acid will work very rapidly, but you don't want to mess with that.

Not sure where you can find a citric-acid based cleaner for consumer use. You might try checking the lables of any type of "orange cleaner" and see if it lists citric anywhere on the bottle.

aluminum does undergo oxidation though, the finish becomes dull. The nice thing about aluminum is that the oxidation forms a protective barrier for the metal.

Whats funny :toothy9: is that its actually works that Mothers has their version of it http://www.microfiber-products-onlin...obaandpom.html

There is actually a device that works extremely well that you can mount under your hood to prevent corrosion which uses VCI. Stands for Volitile Corrosion Inhibitors. I have experimented with it and the **** works. We sell this stuff at work. For example, when a production facility is shutting down a tank (steel) for a period of time, or a large boiler, you shove one of these inside before you close it up (or leave it open) and no corrosion. It works better in a closed environment. I stuck a small piece inside my tool kit once and it kept all the rust off my tools.

Might work to stick under the hood somewhere, but there may also be too much air flow.

Metal corrosion is caused essentially in three ways:

1 - Galvanic - Corrosion of two dissimilar metals in contact with eachother resulting in an electron exchange.

2 - Oxidation - Metal is oxidizes and reverts to it's natural state by adding an oxygen molecule. When iron is found in the groundm, it is actually iron-oxide and then it heated to drive the oxygen out and you end up with pure metal.

3 - Underdeposit Corrosion - A story for another day.

4 - MIC - Microbiologically Induced Corrosion - Resulting from bacteria.

Somehow the VCI inhibits #2. It would have no impact on the other causes., But as you can see in an engine bay, that should be the only one we are dealing with.

Also, aluminum is different than steel and has different properties. I am just assuming that the oxidation may be rust from steel.

cool motor
 

wow, it's really very cool motors, 2#. i LOVE it very much.

No.
