I need to clean up a few chrome bits on Wesleys LX that are looking a tad oxidised (tail light trim, window trim etc). I have used Calcustom Purple Polish and on the chrome that is in good nick and it has come up really well. Just wondering if anyone has had good results with the Aluminium Deoxidizer from the same company?
Cheers,
T

General findings is that THEY ARE f*ckING USELESS!!!!
They strip the alloy back, leave it looking a horrid white type colour, then it reoxidizes over the top in about three days.
BUT the blurb on that website sounds good, and calcustom are very good, so i might get a bottle and try it myself.
Cheers.

The Purple Polish is great stuff so I'm hoping the deoxidiser is up to the same standard.

I can confirm Bombers findings, i still have a almost full bottle at work Mr-T, it looks,smells and works (or dosen't) just like watered down Alloy Acid (mag wheel cleaner) ,it didn't help on ANY of the things i tested it on, (some it made harder to polish)
The Purple polish is great and will impress for sure, but im afraid the de-ox should not be sold on the same shelf as such a great product.

Don't use it....Leaves a horrible finish and doesn't help one bit. In fact it makes things worse from my experience.
Jeremy shuddered when I showed him the bottle of green acid. lol

The reason you are left with that white finish is the polish you are using removes the protective coating on the aluminium, the purple brand is less harsh.
What coating is this ? never seen anything used to coat alloy other than a clear coating of paint, and if it was coated in paint then alloy polish (including purple) is the wrong polish to be using in the first place,
The de-ox needs to contact the surface of the alloy ,it chemically reacts with the alloy itself and will give it a white haze, any coating or layer of paint (non metallic) will create a barrier between the acid and the alloy and then it will not go white.

But the de-ox alloy acid has a similar effect on both Alloy AND Aluminium (sending them both white) , so even if this protecting layer of Aluminium is intact, it will still go white regardless of what polish you prevoiusly used.

It is obviously causing surface corrosion, but tell me, exactly what is it thats pure aluminium that you are using it on? Pure aluminium is very soft, and basically useless, thats why it's made as an alloy with other metals, aluminiums best quality in pure form is it's resistance to corrosion, thats why it's usually only used as a protective coating on aluminium alloy.

i was doing my dissy housing last week and tried a recipy i found on a harley site.
Basicly boiled in a weak soultion of water and vinigar for a white.
Then used some cheap chinese pot cleaning pads (not the metal type) and a stiff tooth brush, Chinese because they are crap and not very aggressive, and usless to clean your pots
took a while, and removed staining back to a nice finish. its not perfect but its pretty good.
i didnt want a beadblast or polished or over restored look.

When using alloy acid on anything on any car ive come across, everything ive suspected of containing a decent quantity of Aluminium, has gone white evey time (unless clearcoated) some Alloy components will then tarnish to a dark almost black colour once rinsed and allowed to dry (common with some engine blocks) i actually don't know of anything on a car that has a "pure" Aluminium coating over Alloy (not that that means it does not exist), but if everything Alloy/Aluminium looking ive hit with acid goes white, how would i know the difference ?
If you can tell me a few examples of what components on a everyday vehicle (a easy car to find) that you know definatly have a pure Aluminium coating over Alloy, i will find one (if we don't have one at work) and test to confirm your theory that the Aluminium coating will prevent the Alloy turning white when hit with some alloy acid.
What about on Chrome?
Not really what id use to clean chrome, but ive never had any issue with acid on decent chrome,(steel bumper bars etc) be carefull on chromed plastic (grilles etc),alloy acid will tarnish some blends of copper rather bad,a lot of chromed plastic is copper coated first, so any stone chip or imperfection in the chrome may allow acid access to the copper underneath, leading to poor bonding resulting in bubbles or peeling (especially if you hit it with high pressure water)

I don't think I said the coating would prevent it, if this stuff you mention is an acid based cleaner, then there is your answer it's simple, it's eating into the aluminium, be it pure or not, aluminium goes to a white powder when it corrodes.What about on Chrome?

It might work on some stuff, but it sure as hell didnt work on what I wanted it to.
Back to drawing board.......

They will have to be buffed and polished, by machine, hand jobs won't cut it.
