i used a brush quickly to get the inner wheel, but I would say the wheel cleaner did about 95% of the work.

DAMN ... the wheel's bleeding !!!

Pretty impressive.
Up to now was using Orange Blast.
Very effective, but not much as that.

Possible to get it somewhere in Canada ?

just used it myself.
I like the way it goes red.
Works best if you have a pressure cleaner.

guys can this stuff be used on exhausts aswell, iv just got a standard tail pipe on my e90 m sport, buts its dull after i wash it. not sure what to use on it?

[Detailers Domain]

make sure they are cool to touch I tried it on my R32 and S4 and it worked well, I would still say polish them out with metal polish.

[canofwhoopass]

Damn, may have to try this stuff.

[phistyle]

I really want to try this stuff since my rims has a lot of brake dust that's hard to get off but it's so freaking expensive...even with the discount code, it's almost $30 @_@

Is this safe to use on gunmetal powdercoating? Will it fade my wheels over time?

Let's see some testing on some very dirty OEM BMW wheels WITH macro setting close-up shots. For all we know there could still be a lot of left over grime on those wheels - everything looks good from afar. Till then, I am not convinced it's any better than what's on the market now.

When Phil at Detailer's Domain posted up some pics of the Sonax brand wheel cleaner in action last week I was impressed and decided to do a comparison for my on edification. My results are my results and your's could vary for any number of reasons including the brake pad material and other crud that gets on your wheels.

Disclaimer: I have no association with any of the products tested or businesses mentioned in this test. I purchased the Sonax and P21 just like any consumer would do.

We start with two very dirty wheels that have baked on brake dust that have been sitting for at least 4 months. Even though these wheels were cleaned on the inside last Summer, a lot of the baked on brake dust would not come off even with a lot of P21 and other cleaners and a lot of brushing with a nylon bristle parts washing brush. Thus as a reference point some of the brake dust has been on these wheels for close to a year.



For all of these photos the Sonax wheel cleaner is used on the left and the P21 cleaner on the right. The P21 is the spray, not the gel. The Sonax is kind of a light gel or heavy foam consistency.

Both wheels were placed in the shade and sprayed with a liberal coat of wheel cleaner and allowed to sit for about 7 minutes.



Because these wheels were so filthy and the brake dust was caked on there was no point in just hosing them off as this crude was going to require some heavy elbow grease to get the worst of the grime off. For normal brake dust on the outside of the wheel a light wipe or brushing should be all that is necessary based on past experience.

This is a close-up to show how really bad the crud was on the wheels.



After considerable brushing and a good rinse we have the two wheels side by side for comparison.



The wheel on the left with the Sonax cleaner has considerably less crude left than the wheel on the right cleaned with the P21. Equal brushing effort was used as best as possible. The spoke area is where it's easiest to see the left over crud.

This is the Sonax wheel up close.




This is the P21 wheel up close.



After more cleaner and brushing the wheels started to look close to what I wanted - clean.



The only thing left on the painted surfaces now is some small tar spots to be removed. I like this look much better but it did require considerable work - as you would expect of baked on brake dust.




So here are my conclusions based on my experience with the Sonax and P21 wheel cleaners:

1. The Sonax definitely cleaned the heavy baked on brake dust best

2. For light brake dust either cleaner will probably work fine

3. The Sonax has a strong acrid odor compared to the sweet P21 odor -

Always use these types of cleaners outside with good ventilator for safety reasons

4. The Sonax removed baked on brake dust that the P21 would not remove regardless of how much I scrubbed

5. I did not detect any dulling of the clearcoat with either cleaner - YMMV as there are many different wheel finishes

6. The Sonax is more expensive based on bottle size but when you need the best cleaning the Sonax is better than the P21 in my limited testing

7. When my current supply of P21 is exhausted I will switch to 100% Sonax wheel cleaner as it removes all the brake dust in my experience which is important on spoked wheels


Keep in mind that your experience may be different than mine. I still like P21 and think it's fine for lighter brake dust. For the heavy stuff or with certain brake pad compounds the Sonax looks to be better at removing the crud in my experience. It may also be easier to remove the heavy crud with the Sonax and a power washer. I didn't test that aspect. I have done that in the past with the P21 and it still did not remove the baked on crud.

I'm using Sonax to get my rims fully clean. Then I'm going to coat them in rejex and maintain them with weekly cleanings.

Phil why don't you stock rejex? It's good stuff.

You can always count on German made Quality!

^^That looks almost too good to be true. What is the active chemical in the SONAX Wheel Cleaner?

[TiAg335i]

There is a primary chemical that does most of the work - just like every cleaning product on the market.

For example, to dissolve iron-based deposits there must be a chemical that can form an iron-soluble complex, although I'm not sure how this product does it without acid.

can't wait to get some of that for my spring detail
