I posted a link under a different thread, but people seemed to like it, so I thought I'd start a new one. Products Tested: -P21s Special Performance Gel Concentrate Wheel Cleaner -Chemical Guys Diablo Rim and Wheel Cleaner Gel Concentrate (cut 2:1) -Chemical Guys Diablo Rim and Wheel Cleaner Gel Concentrate (undiluted) -Griot's Wheel Cleaner The concept behind this test was to see what these 3 safe cleaners were capable of, objectively as possible. Understand that these wheels are not a typical case. Also, given the the condition, I would use a much more aggressive cleaner, but the point was to test cleaners that are safe for any surface, including raw polished aluminum.

That's what you get with a 16 year old car that was owned by a young woman who didn't care about it. OOPS! Fixed it!
:lol: Dylan, you know it's your job to keep that car of her's clean too! It's the only way my girlfriend doesn't get mad at me for being in the garage all the time
yeah those were some nasty wheels, I say diablo would be well suited for well maintained wheels, and for heavily soiled wheels i'd reach for the P21S
have you guys try Brown Royal by Flash? Manufacturers and Distributors Of Professional Auto Detailing Products and Car Wash Cleaning Chemicals
Nope. Even though it is "non-acidic", they still say not to use it on uncoated wheels, which makes me think it has alkaline builders. So, it isn't in the same class as these cleaners.
Nice test. Its nice to see a test done on some really messed up wheels to see what they will actually do. Thanks for sharing. So you are saying that P21S and Diablo are safe even for uncoated anaodized wheels, like say Volks?
Yes, I bought a gallon last year when trying to get some nasty rust/brake dust off of two wheels. It worked very well. It worked just as wheel as the ads on YouTube. The few things I didn't like about it was the smell. Very strong smell that will make you cough if you are not careful. I don't really like the brown color either but maybe that is just me. I did like the price and the cleaning abilities so for the occasional wheels that are pretty nasty, that is what I use. It is also very good on tires. I can spray it on tires and hit them with a hose and they are clean. I typically will still scrub the tires with a brush before rinsing but you really don't need to. With that said, I still love P21 and feel like I can trust it more on expensive wheels(meaning I do not feel like P21 could harm a delicate finish). I also like the fact that it is a gel.
Thanks for doing these tests! I think I might buy another 5L of P21S just to have some on hand along with my Diablo.
Very nice review! Would be great to see how Sonax Extreme performs in the competition vs CG Diablo or P21S
That is what I am saying. I am planning another test to show this. Keep your eyes posted on that blog. I wouldn't quite say that. It just isn't on par with P21s gel. Considering the price though, I think it's a very good option for wheel cleaner.
