SONAX The Beast Wheel Cleaner, Color-Changing Non-Acid Formula, 1 Liter | Fast color-changing, pH-neutral wheel cleaner loosens brake dust, road grime and contamination on a wide range of wheels

I do all our own car washes and have tried many wheel cleaners over the years. I found this one a few years ago recommended off a gearhead message board and have been using it ever since. It's expensive, and it goes quick, but it's beyond worth it. I am never ceased to be amazed how great the wheels look after washing the car. I do use a brush to scrub the wheel, but it's an effortless scrubbing. Then hit them with some ammonia-free window cleaner at the end. Looks brand new after every wash, no matter how bad they were before.

Best stuff I’ve used for brake dust and wheel buildup.

OMG, I was skeptical whether this was work or not. My rims were really bad, caked in break dust, I tried using nail polish removal but that would take some time and a lot of scrubbing. I sprayed this on and used the red brush, in 95 degree weather, not recommended, then when I got back around the car, it dried so I sprayed a second coat and scrubbed faster then rinsed with a high power rinse (it wasn’t that high powered) and BAM. Everything came off. Here’s a picture. I forgot to take a picture of it before but trust me, I was really bad.

The SONAX Beast Wheel Cleaner does a good job of removing brake dust and grime from my rims. The color-changing formula is a nice feature, as it lets you see the cleaner at work, turning purple as it breaks down dirt and grease. While it’s effective on moderately dirty wheels, I found that for heavily caked-on brake dust, it required a bit of extra scrubbing or a second application. It does leave the wheels shiny, but I expected a little more "beast" in terms of power for tough jobs. Overall, it’s a solid product for routine cleaning, but if you have really dirty wheels, you might need to put in a bit more effort. Still, a good option for general wheel maintenance.

This isn’t a paid review, as you can see in the my wheels look brand new now. Grab this spray and a scrub daddy and get to scrubbing the dirt and grime comes off like butter!

I tried all the wheel cleaners at the yard parts store and none made a dent in the caked on brake dust. I ordered the Sonax Beast wheel cleaners at as a last resort. It worked great. It took a little scrubbing with a stiff brush and a second application in a few spots. The only issue was that the instructions on the label are in German.

This stuff is amazing, although not recommended, I used it on the car paint as my white car has lots of rust spots in the paint, I was told this is from the brakes and or just roads... sprayed on and minutes later it removed all the spots, gave it a wax and paint looks new again

This stuff is great for black painted wheels, very strong, easy to spray and no scrubbing, however I have noticed on my Brembo brake discs though it makes them squeal horribly at low speeds. Once I stopped using to clean, they do t squeal anymore.
