Deep talk about wheel cleaners - alkaline, acid, pH levels

Re: Deep talk about wheel cleaners - alkaline, acid, pH levels
How else do you explain that white worming affect? It always seems to start where the wheel has been chipped from road rash or from the impact socket at the wheel lug holes. It always looks like a strong cleaner has worked its way underneath the clear and or powder coat.

I’ve never heard of that term. These wheels had lots of the clearcoat peeling off of them + road rash. Is the worming effect that you’re referring to seen here?

I am not see any of your photos in either post unfortunately

I know exactly what you're talking about. It stems from exposed aluminum either at the backside where it sits on the hub or around chips/rashes as you mentioned.
I suspect it's from corrosion of the aluminum spreading and lifting the clearcoat. I'm sure aggressive cleaners and road containments (e.g. sodium chloride for snow/ice) contributes to it. Though as one of my concerns from my original post, I do wonder if certain pH level of wheel cleaners will accelerate that corrosion.

Coming from a small understanding of aviation grade aluminum, that same effect happens to all aluminum over time, you just have the luxury I suppose of seeing it develop compared to on my plane where it can be hidden under the paint. A chemical too acidic or too basic will cause damage.
Mind you, different aluminum alloys have different tolerance levels of what they can take to some degree. Here's a guide from an FAA circular. I selected this portion dealing with the chemical effects of corrosion but if you Google FAA Advisory Circular 43-4B, that is the latest guidance for aluminum corrosion and control and can shed some light on what causes corrosion in aluminum and why some wheels will be more or less resistant than others.

Well stated...I TOTALLY agree.
It seems that it only takes one tiny 'thin spot' is to get things started. At least that's been my experience.

Don't you live is southern California? Aside from UV, it's the most friendly environment for cars.
The chemistry is there. Reactive aluminum plus strong acids/bases. I just can't see how you think it doesn't happen.

Eldorado is a pretty respected guy and he's give me some solid advice here (thanks make keep it up!) But like that advisory circular states (please take a look if you want to nerd out and get a deeper understanding) different alloys of aluminum react to different PH levels and, I forgot to mention, different types of acids. Also it depends on if there's a coating or not, anodization, alan clad, etc. It's way more than I can understand but when I go to the base in two weeks, maybe I can swing by the airframe shop and talk to a few of the metal heads about this.

I don’t even think wheel bright is that strong in 4:1. It’s cleans my silver oem wheels pretty well but not my black oem or aftermarket that well unless you like to agitate
