Chemical Guys Diablo Gel Rim and Wheel Cleaner Product Reviews

This stuff is worthless. I used a 3/1 ratio and it has very little cleaning power when sprayed directly on my rims. I compared this to just spraying CG Ecowash using same type of spray bottle and the Ecowash removed all the brake dust while the Diablo didn't do much at all. I'm going to try an ONR mix next time I clean my rims, bet it does better than Diablo too.

Great CG product as always. I dilute 3:1 and it helps breakdown dirt/grime on wheels. It is definitely no P21S or Sonax but for the price, it is a great pH balanced wheel cleaner that is great for everyday washes.

I use this wheel cleaner very frequently. The value is great, I cut it 3:1 and it works great. I only use something stronger like P21S when I clean wheels that haven't been cleaned in months.

I received a bottle courtesy of DI. Following the "instructions" and dilluting 6:1 it's pretty watery and needs a brush or cloth to really remove any dirt. Going to mix it at 3:1 and see how that works.

Does it work as well as P21S or Sonax? No. Is it much more cost effective and just as safe? Yes. I use this wheel cleaner on wheels that are in decent shape. Dirty, but not terrible. The terrible wheels get the expensive Sonax or P21s because they just plain do a better job. That being said though this is a great wheel cleaner for the price as long as you don't expect miracles. My favorite aspect of this product is how well it sticks to the wheels. It is a true gel even wheel diluted which allows a longer than normal dwell time.

I bought this product because of its saftey on all wheel types, but the more I use it the less I'm impressed with it. I really need to try P21s to compare, but I dont think I am going to purchase this anymore.

I have gone through 2 gallons of this Diablo Gel Wheel Cleaner and I can say that it is safe on all wheels like P21S Gel, but is nowhere near as powerful. It is good for maintenance cleanings, but it will not strip durable tire dressings the way P21S Gel will. Diluting it 3:1 is really the best bet...any weaker and it just becomes too watery. Any stronger and most sprayers will not suck the product out evenly. While I would recommend this product to someone looking for wheel safety, the cheaper Sticky Gel is significantly more powerful at the equivalent dilution ratios.

I mixed some in a bucket with water, and applied with a brush, gently. After letting it work for a few minutes only, all the dirt and brake dust just washed off. No scrubbing needed.

Im on the fence with this product. Seems the dilution ratio needs to be closer to 2:1 to be effective in my eyes. Still requires a fair amount of scrubbing. Does nothing for cleaning tires in my experience.

For the Ferrari and Maserati wheels, Im not ready to repalce P21s gel with this just yet.

For regular maintenance use, soap and/or a 10:1 diluted degreaser seems to do the same thing for me.

I diluted it 3 to 1 and I'm not impressed. Lots of brushing to get the wheels clean. It doesn't work nearly as well as p21s.

I diluted it 2:1. sprayed it on,dwelled for three minutes,and rinsed. On real dirty wheels it needed a brush.
Still, the best for really bad wheels is Meg's WB.

I tested with 1:4 and 1:5. It both worked well. much like P21s wheel cleaner. But still it is more cheaper than P21s. I just love it. by the way it smells good too. :)

The last 3 opportunities that I have had to clean my car, I have used Diablo for the wheels and tires on my Acura TL-S. I have been very happy with the results. The product has a great bubble-gum scent. I diluted it 3:1 like the instructions recommended, and it worked great to remove all brake dust and gunk that had built up after a week of rainy weather. It suds up nicely, rinses off easily, and I like how it lasts longer than some other wheel/tire cleaners that can only be used at full strength. This is a very satisfying product to use, and it is one that I would recommend highly. Gallon purchases are in my future.

This stuff is great. I used it at 4:1, sprayed it then walked away for a couple minutes and when I came back the rim looked clean. I still had to use a brush for some parts but the grime all came off pretty easy. I will definitely be buying some more.

I purchased diablo the day it was released from CG. I actually did a head to head comparison to the 'green stuff' and found that they work equally well. I would not mix diablo 6:1 though it becomes to 'watery' I mix 3:1 and it is great, plus you still get a great value compared to the other ph neutral cleaners. 3x more product for the same price.
