This weekend, I checked out the wheels on Ben Chou's car, and was frankly astonished by how brake dust free they are. Not just the wheels, but the greasy bits, like the calipers, pads, et al. They seriously look brand new; after 20K (?) miles, you can read the name of the brake mfgr. as clearly as you could when the caliper was bolted on in Regensburg.

I asked what miracle product he used, and he said P21S. So I ordered some from carcareonline, and tried it out tonight.

Nice. The dust from my Hawk HPS pads is nowhere near as intense as the dust from the stock Textar/Jurid combo, but the P21S was able to get at and remove hard to reach dust that had collected from the old pads around the lug nuts, etc. Application was easy, just squirt on and then spray with a hose (I wiped a bit with a soft brush, too). The wheels have a shine to them that I haven't seen before. We'll see if after a few applications really caked areas such as my calipers start to come clean.

The P21S is expensive, but well worth it, IMHO, especially if I can keep my calipers clean enough that I don't look like Night of the Living Dead when I change out my pads.

Hmm...

I'm running out of Griot's, and as good as I feel it is, its not cheap either, and I'm up for an alternative. I keep reading that the BMW cleaner is relabeled P21s, so if that's the case I'd be willing to give it a try.

I'm using the BMW stuff right now. It does do a good job, but with my wheels, and your Alpina's, a little brushing is/will be necessary. Never used P21S for direct comparison, but I am pleased with the BMW stuff. It does seem a little aggressive, at least the odor of it.

I was using P21S but found that it did not do a great job, I have been using Meguiar's Hot Wheels Cleaner with better results. Granted it is more acidic. I think P21S is good if you clean your wheels more often than I have been---but I will never let them get like Alan F's.:yikes:

I noticed the acidity in the bottle of Meguiar's and to be honest I think there is some level of it in the BMW version.

Alan F's wheels probably look clean compared to Alee's since he now lives in the city. His poor car is probably going through withdrawal from lack of cleaning and driving. :eeps:

It also smells like something bad, but it works pretty well and the instructions are to wet the wheels first which I assume cuts the acidity. I have not found any wheel cleaner that you can just spray on and hose off, I am on my third wheel brush in 8 months.:yikes:

The moderator of this forum is a slug:lmao:

I use a cheap detailer's choice brush that is trapezoid shaped, the handle is red and the brush which is nylon is yellow. Gets in to most spaces but does not wear forever.

i had both products back to back, the bmw product is NOT relabeled p21s, but it is a pretty good product. esp if you have a high pressure spray...

Did you use the regular P21S cleaner or the concentrate gel?

I have not used the standard wheel cleaner, but the concentrate gel is fantastic! From what I understand it is a tad stronger than the regular and since it is in gel form it sticks to the surfaces better after being sprayed on.

JST,

Glad you liked the P21S. If you do like it, I would order the 5 liter jugs. Wait until they are on special and you can pick them up for about 62 or so. I think they go on sale in March.

PS. If you really want to clean your calipers, swing your car by my house and between the P21S, some light brushing, and a pressure washer, you won't need to even wear gloves next time you work on your car.

They make a gel version for people that don't clean their wheels that often. The formula stick to the rim more and you get less run off. Trade off is that is is slightly more expensive than the normal stuff. I have used both, but since my cars is regularly washed once or twice a week I have no use to spend the extra for the gel formula.

JST,

Now it is time to do something about that very dirty door jam of yours!:yikes:
Already taken care of. That's the window mechanism lube that the dealer helpful sprayed in there trying to fix my window problem. It also leaks gradually out all over the ground effects. Really nasty stuff.

Do I need to get an alter-ego, too?

I was using the standard spray and I heard the gel is stronger. Maybe after I exhaust my spray I will try the gel.

That'll be a year or so since you aren't allowed to spend time cleaning you car on the weekends:rolleyes:

Where's that bum of a moderator to help on this topic:dunno: :confused:

Another nod for P21S

I used P21S extensively up until about 5 years ago when the cost became a bit too prohibitive in my opinion, so I've since changed to the BMW Wheel Cleaner like some others here.

It's not as good as P21S, but it does a tolerable job with a little elbow grease as this pic kind of shows on wheels that have been driven almost 12k miles, after 18 months of use and abuse.

Very nice--what do you use on the tires?
