meguiars meguiars what have you done !...

[swanicyouth]

I'm going to go out on a limb here and make some assumptions. Feel free to disagree.

1. From the best I can tell from the photos, the calipers are factory Brembo, similar to these:

2. The Megs "All Wheel" cleaner product is just a soapy high pH / APC type standard wheel cleaner.

Ok...

Now, the way I see it, there are only a few possibilities of what's really going on here:

1. The cleaner was applied to HOT calipers. I realize OP says this didn't happen - but it sure looks like that to me.

2. The cleaner was left to dry neat on cool calipers.

**** Lets assume for now the calipers' finish is actually permanently damaged and this merely isn't white product residue left that can simply be cleaned off ****

As far as not getting your wheel cleaner on the calipers - that is kind of crazy. These calipers are probably painted or powder coated with a "paint" similar to what's applied to the wheels. Of course if you have nice calipers and are into detailing, you are going to want to clean them when you clean your wheels.

What are you supposed to use, Brake Caliper Soap????

Can you link me to where I can purchase that?

When using any wheel cleaner, you can not apply it to hot wheels/calipers and you can not let it dry on the wheel. You have to work on one cool wheel, rinse it thoroughly - and then move on to clean the next wheel.

If you use this method, you likely can use any wheel cleaner including strong acidic wheel cleaners, without causing damage to the wheel or caliper finish. Some pros exclusively use these types of cleaners on all types of high end cars without issue.

This Meg's product is as OTC as it gets. These products are designed to be safe with most of what's out there - and there are a lot of Brembos out there. I would think if there was some special ingredient in the product that can damage the finish (assuming correct use) - it would have been known by now.

I tried to rub it off couple of days ago with my fingers (speaking of being super frustrated and little time to spend) and i noticed that it might come off !..

Why wouldn't you try this immediately? This could have straightened out your issue right from the get go.

Then later you actually tried this and were only able to conclude it "might" come off??

I agree with swan, that meguirs is sold locally at any auto part shop. It has to be safe for any type of consumer to use.

At my job we use a more concentrated wheel cleaner and I haven't seen a big issue with the calipers. We also clean the wheel no matter the temperature of the wheels. I've seen them steam because of how hot the brakes are.
I work for a Toyota delership so brembos don't come that often.

Taking off rims to clean them with an ALL safe rim cleaner is absurd. Doesn't matter how small the fine print is, nobody is going to expect to have to on an ALL safe rim cleaner, well except for two members here. I'm guessing that's because it was a Maguiar's product, that's why we saw those responses.

A rim cleaner that can clean ALL wheels should be
safe to spray near and around any undercarriage
including the braking system...

Lesson learned never to trust any brand claiming it is SAFE on all wheels, regardless of what brand it is, that's the lesson I learned !...

Saying: "Safe on all wheels"...
That's where you guys are wrong!!

This is the deal:
Meguiar's Hot Rims All Wheel & Tire Cleaner
is safe to use on all (OEM) factory coated wheels.

What about the factory valve stems and lug nuts? It doesn't state if it is safe on those.

Or, is it recommended to clean your wheels without getting the cleaner on those components as well?

Is that information in the MSDS? Or do I have have to call Megs to find out?

I see a lot of shills posting in this forum.

Just put him on ignore like I do.
It's a much better forum that way.

Are they uncoated metal?

No my valve stems are" rubber". But l have to do some research to see if they are aftermarket, OE, OEM, synthetic rubber, coated rubber, or uncoated rubber.

It looks like that little pin thingy that lets the air out may be stainless steel (maybe uncoated aluminum or real silver?), and the core of the valve could be brass (maybe 14k gold?) or some other type of alloy.

The valve caps appear to be composed of some sort of black plastic type of material, so I'll have to contact the manufacturer of those as well.

Obviously, I have a lot of research to do.

Why anyone would use a wheel cleaner...
one with a pH of 13.56; one with a hazardous
warning: "May be corrosive to metals"...
anywhere near braking system components
remains their personal choice.

I don't; and I'm sure that many other
people don't as well.

I mean:
What harm could happen if someone would?

Just get a APC like Meguiars D101 and dilute it to your needs. All these "specific" cleaners for "specific" parts on vehicles is a sham to get your money.

What he said......I use D101 on wheels unless they are really, really bad....in which case, I break out the Griots Heavy Duty wheel cleaner

Yep. Regular old car wash soap works for me.

It is sold and on the shelves, widely recommended, and trusted brand, does that answer your question ??...

Also I was sure my wheels were metal not aluminum, next time I will apply this sh*t using a dropper only on the specific parts am 100% sure they were metal, it is either that or this brand is total crap (sold for 4 bucks I guess vs. sonax and other pH Balanced sprays that are double the price), but what you pay is what you get !...)

 

[emmjay]

This is pretty much why I have NOT tried the Meguairs consumer line wheel cleaners till today. Their instructions are just not "easy" for us normal people to use. Especially HOT rims.

Its just not common place for everyone to know if their wheel and brake components are "Factory coated". I agree with you on their instructions being pretty sh"t lol.

I use only Sonax full effect wheel cleaner and Meguairs D101 APC for all my wheel and tire needs.

I do love meguiars products - but not all. If the product is made to be "easy to use for the consumer" it should be usable everywhere and by everyone. No one uses wheel and tire cleaners without getting some on their brakes, calipers, rotors etc.

 

[aliitp]

Maybe it's residual, and can be rubbed off. It seems Meguiars would know better than to place it's consumer in such a predicament.
A rim cleaner that can clean ALL wheels should be safe to spray near and around any undercarriage including the braking system, especially if it's going to be sold to the masses OTC, IMO.

I liked your response and glad to let you ALL know it was indeed residual, not as serious as i thought, sprayed with armor all quick detailer (the brand I trust and use for long time) and used the "Wolfgang Finger Pockets" to clean the brakes, and voila ! it wiped off easily, the only issue is the Cadillac writing was a bit affected, guess this sh*t ate the coat or whatever that is applied over, but I can't notice any notable change in the colour or material of the brakes which looks dull grey btw, but still looks factory anyway ...

 

[Eldorado2k]

I liked your response and glad to let you ALL know it was indeed residual, not as serious as i thought

So this was simply caused because you didn't thoroughly rinse the wheel? Were you using a nozzle on your hose? What kind of Cadillac is it? Any pics?
