Bought this to try a decent RIMs cleaner from a KNOWN brand, I followed exact instructions and I will say them again, wheels were sitting in garage parking for 1 week so no chance they were hot, even though I washed with cool water, sprayed with ph balanced soap, cleaned with a sponge, rinsed again with water, sprayed all over the rims to remove brake dust, some of the product came in contact with the disk brakes, then used a soft brush all over the rims to scrub the dirt off, then immediately rinsed !!... after rinsing i was alarmed when i say weird coloring sort of haze on the disk parts, i immediately gave it a blast of water pressure, but that didn't help a lot (if any to be honest), see the pics for yourself and judge if this product deserves anything more than 1 star, which i doubt it does !...

Are those calipers unpainted metal?

If so, that may be the problem. The safety data sheet for the product states that it is corrosive to metal

I am only guessing here so hopefully someone else will chime in with their thoughts

I have also seen some iron removers do the same thing to unpainted calipers before.

I use Megs All Wheel & Tire Cleaner all the time and haven't had any issues except MAYBE accelerated surface rust on the rotors (which goes away as soon as I drive the car).

I have the same experience as Don. I have been using this product for the past 4 years, I try other products but for the price and quality I keep coming back, especially when it's 2/10 at an auto store. I have used this for about 90% of the wheel/tire cleanings in my 97 Maxima when I still had it. I now use it on my 2014 Mazda 3 as well as my wife's 2012 outback. I never had this happen.

This product stained my rim as well, but in spots...so the clear coat must be failing in those areas. I wasn't happy either. Your caliper must be a different material than your rim. So sorry!

 

[TTQ B4U]

I've used it on mine as well with no issues. However, in the end I have since switched to Griot's Wheel cleaner buying it a gallon at a time. Non acid based, and works as good as Sonax and others without worry of harm.

To preface:
I've always found this Meguiar's
product to perform as advertised.


And (From the picture):
I don't see where there were any damage(s)
to the wheel or tire from using this particular
Meguiar's cleaning product.

Is that a correct observation?


Also:
I agree with Lawrence's corrosive assessment;
and the importance of MSDS's information.

RE: Braking System Components

This is another example of why I remove the
tire/wheel assemblies before performing this
type of cleaning task...with these kinds of
cleaning agents.

Takes away my chances of putting product
overspray anywhere that could possibly
affect any of the vehicle's braking components.

Sorry for the low resolution image i didnt know the forum would downscale it, here is a higher res image:

Nothing happened to the rims as far as i noticed, but BOTH front wheels brakes (both right and left) suffered from the same issue after spraying this sh*t over it !...

IMO:
-You shouldn't have sprayed this Meguiar's
"Wheel and Tire Cleaner" over any
braking system components.
-It's not made, or intended, for that purpose:
no matter the process wherein those components
were encroached upon.

Is this your own vehicle or a customers? If it's your own Cadillac, what year and what exact model is it? Check your owners manual and see if it says anything specific about keeping certain kinds of cleaners away from the brake components. And even if it does, it oughta warn of this exact outcome or else you've got a legit argument for them to replace them free of charge. To be honest I'd be 0% PO at Meguiars and instead 100% PO at Cadillac for what appears to be stock brake calipers that can't even make it through a Non Acid All Wheel Cleaner. What the heck are they even thinking?! I'd have been at the dealership demanding an explanation from them. Show them the bottle, it says "all wheel"

Who sprays on wheel cleaner without getting some of it on the brake calipers and rotors? Cmon Bob...

No...you c'mon!
Every wheel cleaner is not created equal.

If you had taken the time to read my previous
posting(s) in this thread, you would have seen
what my processes are when using the Meguiar's
product, (and ones similar to it), that happens to
be the subject matter of this thread.


I don't go about haphazardly spraying car-care
products around wheels, tires, and braking
system components.
That's one thing you can definitely count on!

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.

 

[Crispy]

I agree Funx650, if you are using an aggressive cleaner on a surface you need to heed the manufactures recommendations. I'm no Pro but, if you are then not applying to surfaces not recommended should be part of your knowledge base. As an aside the disc will return to normal after applying the brakes, so take a drive and relax.

 

[expdetailing]

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.

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 !..

I will try to clean it next time with water, soap and the infamous speed master wheel brush as it should arrive in no time now !..

I wouldn't remove the wheels and clean them as am living in an apartment and that's is absurd to say the least that's why i bought this 13 bucks bottle claiming to be SAFE on all wheels from a hardware store over here and was planning to read the instructions CAREFULLY (AND I DID) then apply it, I didn't even leave it for more than 30 secs tops and asked the guy to blast it off with water pressure, weird thing is though, while the front disk brakes BOTH got affected very badly, the back car brakes (pure metal I believe) didn't get effected at all as far as i noticed !...

 

[wing commander]

Bob's advice is for helping anyone who is willing to listen to just take precautions until you have proven that a product is compatible with your task. Test in a small scale can prevent large scale mistakes.

 

[VISITOR]

i think all of us have experienced something like/similar to this at some point with any product, consider it a lesson learned..

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 !...

This. I see a lot of shills posting in this forum.
