Thanks Gents.
I must say, the magnesium wheels were heavily oxidized when
I unearthed the car. I went through at least six different cleaners
before I found one that actually did something.
In the end, I used WEIMAN Metal Polish.
The bottle says for Brass, Copper and All Metals.
With any kind of cleaner/polish, it requires using a little
or a lot of elbow grease. Trust me, a lot was used along the way.
When it was all said and done, those wheels went from a
dull blackened cast gray to a smooth clean gun metal shine.
All of the other cleaners refrained from oxidizing the surface -
(turning black) and basically sat on the surface. I used soap and water
between applications because the other cleaners/polishes contributed to the
difficultly of removing the stained, aged surface of the wheels.
Also, not all cleaners can physically be mixed - one on top of the
other while your rubbing it in. Since a heat is generated when rubbing into
the surface of any metal and magnesium is a reactive metal.
Its highly flammable and cannot be extinguished with water.
Its not necessarily the rubbing that would ignite it rather the wrong
combination of cleaners reacting under pressure. Sorry, I didn't mean to
start a chemistry thread here. The nice thing about magnesium is that its
light weight and durable. Of all the cleaner/polishes, I would have thought
that Mothers Mag wheel cleaner would have done the job. It didn't.
For those of you who didn't know, Mag is not an acronym for a style
of an aluminum wheel, its short for Magnesium. I found Mothers Mag wheel
cleaner to be used more for taking light oxidation off of aluminum and
chrome. Its not strong enough for heavy oxidation on magnesium.
For the first time during this expensive project of mine thus far,
the least expensive product was the best for my application.
Have a great new year.
