KOCHCHEMIE Magic Wheel Cleaner - Powerful Rim and Rim Well Cleaner; Acid Free, Dissolves Iron Particles Using Visible Red Discoloration, Excellent Adhesion and Viscosity (500 milliliters)

I recently purchased a used BMW. As many of you know, BMWs are notorious for their brake dust.The previous owner of said BMW didn't have the same level of, shall we say, meticulousness with regards to keeping this wheels clean. The wheels, when I took possession of the car, looked like they had only been half-heartedly cleaned over the years, with a lot of build up in crevices and hard-to-reach spots.Enter Magic Wheel Cleaner. I followed the product's instructions and, voila!, the wheels came out looking great. For some of the more stubborn spots, I had to get in there with a rag and scrub a bit, but the product had loosened up the bond and it wiped off easily.Works as advertised. Highly recommended.

Works very well, all brake dust etc were removed without scrubbing

This company makes THE BEST cleaning tools/chemicals for your car. I use this tire cleaner in the beginning of the wash and can see it change color as it eats the caliper debris and dust from the wheels. Worth every penny. Side note: Check out their other chemicals too, you won't be disappointed.

Got the rims extremely clean.

Product does what it is intended to do. Melts away brake dust and crud from wheels prior to spraying with water. As others have noted, this liquid is strongly perfumed. Must store in the garage or outdoors.Single bottle is good for spray cleaning about four, very dirty 20" wheels. *My wheels are all ceramic coated and this is an effective cleaning agent.Also - after purchase of second bottle, went ahead and bought the giant container and continue to refill to spray bottle, using a narrow funnel and latex kitchen gloves on the hands.

Stuff works great on matte black wheels. Would definitely recommend if you’re looking for something stronger to break down down break dust and built up dirt and grime

My car puts out clouds of brake dust and I have tried about every wheel cleaner out there and NOTHING compares to MWC. Spray on a dry wheel, leave for a few minutes and rinse well. I used my garden nozzle on jet stream. After that dry wheel and done. It is pricey but for me it’s worth the extra money for a product that works as advertised!

This product works amazingly well. Unfortunately the spray trigger broke during my first use. Hopefully future iterations of this product address this. I'll be watching reviews to see if anyone has experienced the same.
