Brake dust revisited

Brake dust and its removal/prevention seems to be an ongoing problem for many detailers. Replacing your OEM brake pads with low-dust after market pads will reduce the dust problem, but so far as I know there are no pads that will eliminate brake dust. This still leaves us with the problem of dealing the dust.



There are many special wheel cleaner products on the market, each with its own hype and its loyal band of followers. I don’t endorse nor recommend any of the special wheel cleaner products because I don’t think that they are needed and I haven’t used them for a long, long time.



I use a secret wheel treatment that allows me to clean off the brake dust usually using nothing more than a cotton towel and a spritz of distilled water - - only occasionally do I need to add a little car shampoo to the water - - and heavier pressure than lightly wiping is never needed.



A year or two ago all of the wildly differing suggestions/recommendations on this and other detailing forums led me to do some comparative experimenting. I started by doing a thorough cleaning and polishing of all four wheels, then applied one recommended product to the left side wheels and another product to the right side wheels. After driving for awhile I would then compare the dust accumulation on each side and the ease (or difficulty) of removal. Another thorough cleaning, the winning product on the opposite side and a new product on the other side.



It didn’t take long to realize that all of the carnauba waxes attracted a lot of dust and were difficult to clean without using a special cleaning product and/or a lot of scrubbing. Closer examination and a little experimenting showed that with even fairly light braking the wheels heated enough to soften even the best carnauba. The heat softened wax retains a great deal more dust than an unwaxed area! Quite a bit of the retained brake dust is trapped under the surface of the wax and cannot be removed without removing the wax.



Progressing on to the synthetic protectants showed a marked improvement - - much less dust retention and much easier cleaning. The “combination� synthetics such as Blackfire and Platinum UPP did not do as well as the “pure� synthetics such as Klasse and Zaino. Zaino attracted/retained slightly less dust than Klasse, but IMO Klasse was the product of choice because of its ease of application.



Recently I decided that it was time to compare my winners to some of the new (to me) products. As expected the carnaubas were poor perfomers, and the combination synthetics such as NXT and Wolfgang did not come up to the level of the pure synthetics. Menzerna was as good or maybe slightly better that Klasse for dust retention, and was easier to clean that either Klasse or Zaino.



I think that I will continue to use Klasse on my wheels and not switch to Menzerna because if you’re not very careful when applying Menzerna it’s easy to leave too much product on the wheels - - and this can lead to pink stains that are very difficult to remove.

My secret wheel treatment to to use a good quality synthetic.
 
Very interesting topic. Brake Dust is one problem I don't have with my car but my fathers new STI Subaru has big brakes and lots of dust. I've been using Ferrodo Heavy Duty (mid to high range) brake pads on my car and there claim of being dustless is about 99.5% right. I get road grime on them but they are well protected with 3M premium liquid wax (synthetic) and every time I wash her, they are cleaned and protected with Pacer Nitro Wash N Wax which has synthetic polymer wax as one of it's ingredients. It washes brilliantly and the polymer ensuring that there is always plenty of wax on them. The shine is not world class but certainly very pleasing to the eye with a fine mirror finish



Acid wheel cleaners are outlawed from my detailing with only Lanotec Citra Force (de limolene citrus based), Malco Brake Off and Omikron Magnificent being used. If it's possible I'll try to use high pressure water only when doing wheels. The Klasse SG has some work ahead of it to protect my father's car, both on body and wheels. We shall see



Truly amazing that alot of high to top of the range street and racing brake pads produce a hell of a lot of dust. The gold wheels on the STI are black now. haven't done his car since he brought it home. Must do his car on thursday.



Brake Dust sucks big time.
 
When you have Klasse on your wheels, then what do you use to clean the brake dust off? I figure most wheel cleaners are harsh enough to strip Klasse, even the non-acid ones as usually are usually alkaline



When I first start cleaning cars I use to sit there with a soft towel and bucket of soap... It didn't take me long to realize a wheel cleaner and a soft sponge cleans many times faster. I now use PRO's C-42 Non-Acid Wheelie Clean. It comes concentrated 10:1 and it really does work like a RTU wheel cleaner when mixed correctly. I have found sometimes concentrated stuff when mixed according to the directions is too weak. Not this stuff. So, I have 5 gallons concentrated, which is 55 diluted. I won't be buying wheel cleaner for awhile.
 
Nick, my wife has a Mini with white wheels also. I dont think Ive ever seen anything as bad as this car for brake dust. I recently got my hands on some Michelin Brake Dust Repellent. Its an aerosol that you just spray onto the wheel, let foam for 15 seconds, then towel dry. Takes about a minute per wheel to apply. Ive been testing this a few weeks now. This stuff really does work. It should be out in a couple of months.

Yeah, I have some low dust Hawks brake pads on my car and Klasse AIO on the wheels, works pretty good, although I am always looking for an improvement. Haven't been able to find much that is better than soap and water on the wheels, anything else is just too harsh.
 
What also compounds the problem of brake dust is the type of wheel that your car has. Not too long ago the wisdom of some automakers was lacking when they designed wheels like this:

While I currently use Eagle One A2Z, I would like to find a better alternative since the product has a very harsh odor and can harm the eyes. I'm curious in trying s100 total cycle wash. Anyone experiment with that?

Both of my “playâ€� cars (a Z3 and a MINI) are seldom washed. They usually get a QD wipe down after each drive and spend their free time in the garage covered with flannel bed sheets. The paint QD is Crystal Mist and the wheel QD is Sonüs Acrylic Spritz.



My Klasse protected wheel procedure is to mist the wheel with distilled water and wipe off the dust with a terry towel. After doing all four wheels (less than 5 minutes) I spritz with Sonüs and wipe with a MF towel. Occasionally add another application or two of Klasse HGSG.



I you have carnauba on your wheels, then you need to strip the wax to get rid of the embedded brake dust. That is why most of the dedicated wheel cleaners stress that they’re “non-acid� products - - they have to be alkaline to strip the wax. IMO if a person insists on using carnauba on his wheels, then a dish detergent would be a better choice than any of the dedicated wheel cleaners.

When you get more experience with the Brake Dust Repellent a full review would be appreciated. I’d heard about this three product package, and I’m hoping that each product will be available separately.



My Z3 dusts as badly as the MINI - - it’s my understanding that the German equivalent of our DOT requires the use of very soft brake pads.
 
Tell me about it, I religiously wipe down my wheels with a sheepskin mitt after EVERY drive
 
NozeBleedSpeed,



Sounds like this new product you are using is light years ahead of a similar product I used a few years ago which I don't see on the market any more. I think the manufacturer was "Classic" and it worked the same way your product does, it just did absolutely nothing for repelling brake dust :down

I wanted to take a picture similar to your “product collection� pic, but I didn’t have enough room in my driveway.



This is my emergency mobile detailing kit that I use at long stop lights.

If your MINI driving wife hasn’t already found it, then point her to NAM as an excellent MINI resource.
 
Nick T--



That looks awesome! Similar to how I carry little 2 oz bottles of my polishes and some mfs with me :up :up

Nick T,



Am I missing something here? In the third paragraph of your first post in this thread you said you use a secret wheel treatment. Are you talking about Klasse or what?:nixweiss
 
stevet - - -

You have my apologies for being misleading. That was my attempt to get people to pay more attention to what I was saying - - since I think that many new detailers think that there are "secrets" that the more experienced details only share with the "in crowd" and hide from the noobs.
 
Nick T one I noticed missing from your evaluation and I know its not a boutique synthetic and its cheap but have you looked at Nu-Finish for the wheels .. I have had better luck with that than Klasse/Zaino.



Intel486 on my own wheels I use nothing but a dedicated mitt and the tail end of the current car wash water. Frequent washing = no harsh chemicals needed.
 
Nope - - I've not tried Nu-Finish. Based on the advertising that I've seen my assumption has been that it is not a quality product.



The reviews that I've seen (3 on Autopia and others elsewhere) have been less than enthusiastic.
 
I was just wondering about what you all use to clean your wheels. I may end up doing it on my truck but it is far from garage kept and is used daily. I'm a mobile detailer and see vehicles that haven't been washed in weeks and are driven daily. I have to use a dedicated wheel cleaner on them.

Actually it is a decent synthetic .. just suffers from the lack of hype/marketing/packaging. I'm not sure with the with the technology today that Nu-funish will produce the gloss of the Klasse/Zaino products but for a wheel protectant it will last as long as they do and do the same job ..



If you get a chance .. give it a try on the wheels .. let us know.



I have Klasse/Zaino/Wolfgang and I still fall back on it for the wheels.
 
I've got to agree wrt using NuFinish on wheels. While I wouldn't want to use the solvent-heavy one step on my body paint, it's great for cutting through grime on wheels, and leaves a fairly long-lasting sealant behind. Looks decent, lasts quite a long time . . . the only gripe I had is that NuFinish can be a bit dusty, and if you miss some residue in nooks and crannies, it can be annoying to try to remove in the future.



For $6 or so, though, it's cheap and effective for wheels IMO . . .
