One of the most common things for people to ask me about are wheel cleaners. While I certainly have not tried every wheel cleaner on the market, I have tried a few of the major ones and I continue to use them because they work very well. Here are some of my thoughts on Sonax Full Effect, CG Diablo Gel, and P21S Wheel Gel.

It is important to remember that having the right wheel cleaning tools is also a big part in being able to quickly and easily clean your wheels.



Note: "When caring for your wheels it is important that you have the proper products and tools. It is also important to know what type of wheels you have so you use the proper products on them. If you have factory alloy wheels, chances are they have a layer of clear coat on your wheels. This makes things easy because you can use a variety of wheel cleaners without worrying about oxidizing your wheels finish. You can also treat them like you would your clear coat on your paint, which means you can wash, clay, polish and protect your wheels. After market or upgraded wheels that have a high polished finish or bare metal need to be treated carefully, otherwise you may oxidize the finish and potentially damage your wheels.

Your wheels should be completely cool when you start to clean them. If you have been out driving, even just a little bit, give them ample time to cool down before using any cleaner on them. You can spray them down with water to help them cool down but it may take some additional time for them to reach air temperature so you can begin cleaning. Clean the wheels in the shade whenever possible to avoid water marks or rinse them frequently while in direct sunlight."

My current "go to" product for significantly dirty wheels has been Sonax Full Effect Wheel Cleaner. This product is sprayed liberally onto the dirty area, agitated with wheel brushes, wheel woolies, and/or wheel sponge/mitts in order to quickly and easily remove even the heaviest buildup.

You can see it has a substantial layer of dirt, brake dust, road grime, etc...

Sonax Full Effect wheel cleaner was sprayed liberally on the wheel. The chemical starts as a bright green and turns purple as it starts to react with the dirt and brake dust that cover the wheel.

Here you can see the color change as the wheel cleaner begins to work and the dirt and contaminates start to flow from the wheel.

After agitating with various brushes and wheel woolies, you can see the amount of grime that is coming off of the wheels.

After cleaning (tires dressed as well)... a significant difference.

Another product that I was very pleased with was P21S Gel Wheel Cleaner. This product seemed to work quite well on rather heavily soiled wheels (and therefore was obviously effective on lightly soiled wheels as well). The thicker "gel" formula allowed it to cling on the wheels which enabled you to let it dwell on the wheel for a longer period of time before proceeding with agitation if you wished.

Wheel cleaner applied to the wheel, prior to any agitation. You can see how it is still clinging to even the very top of the wheel and not simply running off.

After agitating with a wheel brush and wheel woolies, the wheel looks perfect (tire was also dressed, of course).

A favorite of mine for routine maintenance (ie wheels that are cleaned weekly) is Chemical Guys Diablo Gel - Diluted 4:1 with water. This is a more cost effective wheel cleaner and works well to clean up light dirt and brake dust.

CG Diablo Gel Sprayed onto the wheel and left to dwell for a minute or two. The product starts to cut through the brake dust and grime even before it is agitated.

After a quick pass with a wheel brush and/or wash mitt/sponge the wheels look as good as new (tires were also dressed in this picture).

3 of my favorites out of all the wheel cleaners I've tried. Nice review.

I love the P21S Gel the most but the price is very steep.
 
my go to is SFE as well and i have also tried p21 and diablo, ill give the slight edge to diablo over p21 only because of the cost and smells good too lol
 
Ive been thinking about switching from ironx to sonax for dirty wheels. The reason being because ive had ironx, in 3 separate cases dull the finish so bad that i had to spend a significant amount of time polishing the wheels back. This happenes 3 times (on slightly older vehicles), once on a near mint condition 93 honda accord se, a 97 jeep grand cherokee and an old 90's gmc truck...all with factory clearcoated wheels.
Product did not dry on surface. Let dwell agitated, rinsed, dull as heck!
Have you ever experiwnced this with sonax?

Its funny...on the old truck i used iron x to clean 2 of the wheels. After noticing the damage i tried wheel brightener on the other 2. ..which caused no damage.
 
Nice review. I just used 1Z Color Tec today and that one is very good.

^Buying these products in bulk helps make the cost a bit more reasonable.

^Diablo is the only one that smells good, no doubt about that. Sonax smells terrible, and I don't recall any odor from P21S.

^I've never experienced that with Sonax or Iron X (though I rarely use IX on wheels). You have probably done many more vehicles than I have, so your sample size is much great I would imagine.

Nice review. I just used 1Z Color Tec today and that one is very good.
^I've heard that is a very good cleaner as well. Once I get through my current gallon of SFE I may have to pick some of that up.

Let me tell you why it's very good. Before I was using Trix as my iron product and this is much better. The 1Z foams up and is very concentrated. I used too much at first. It seems to have a "soap" component to it as well. It smells bad, but no where as bad as Trix.

One thing is, because its so concentrated, it takes some rinsing to remove. I'll only buy 1Z from no on. Its also much cheaper than similar products and comes with the great 1Z sprayer.

I used to use Diablo as well, but found out Sticky Wheel Cleaner works just as well and is much cheaper. Its also more concentrated.

I also use Meg's Wheel Acid on occasion, or just to clean something (anything) nasty:

no extra charge for the pictures ;)
 
Sonax is my go to product for dirty wheels especially for BMW wheel.
 
Very nice review. I have yet to try SFE. Currently really enjoy Wolfgang Über.

BMW wheels make excellent candidates for wheel cleaning reviews. Lol
 
Consider Autoglym non acid wheel cleaner. Unfortunately AG doesn't carry it yet (Nick still hasn't tested the sample I gave him almost a year ago-hint hint) but it does a fantastic job - about $40/gallon delivered. Shoot Nick an email guys and ask him to give it a test drive. It would be great if AG would/could carry it.
 
"I use the Chemical Guys Foaming sprayers... the above images of Sonax FE are using said sprayers. You can see the reflection of the bottle/sprayer."

Perfect

Will try it next time
 
Off Topic... Jeremy, your PM box is full... was going to PM you something but was denied.
 
These are the three that I am trying to decide between for my "primary, go-to" wheel cleaner. I just picked up a bottle of 1Z so now my decision may be even harder! Price is not so much a consideration for me, as I am just a enthusiast and the difference in price over the course of a year is not that big of a concern. I just want the "best" and any and all feedback you can give would be greatly appreciated. I own bottles of all of them, just deciding which one to get the gallon(s) of!
 
Great write up. I have been seeing some really dirty wheels that are poorly taken care of and have been struggling to get them anywhere near meeting my expectations, let alone my customers'. Some new products try. Thank you!

At $40/gallon delivered, Autoglym non acid wheel cleaner is the best product out there. I've tried P21s gel, Wolfgang and the Sonax - all good but none better and the gloss that the Autoglym leaves behind is simple the best imo. Send me a pm and I'll give you the contact info for purchasing.
