Koch-Chemie - Alkali Wheel Cleaner - High-pH Wheel Cleaner for Wheels and Tires - Dissolves Dirt and Brake dust Without irritating Skin - 1 Liter

This stuff is great. Diluted about 7:1 and I have been able to do no touch wheel washing with a pressure washer. Removes all the nasties and the brown from the tires. I dispense in a cordless foam gun and it foams up great on the wheel. Seems like a more expensive product, but once you dilute it is actually cheaper than all the no-names out there.

The product is really good. I highly recommend it. It truly works. I use it professionally.

Worked great and really attacked the brake dust!

This product works very well for caked on brake dust but when I shoot it in windy conditions it can get in my eyes or inhaled by accident so just for that 4 stars but the dilution ratio 1:10 and the quality is really good

I'm a little bewildered by the bad reviews. This is one of the best wheel/tire cleaners I've used. I dilute it about 1/9 in a foamer, foam it on the wheels, tires, and wheel wells, then foam on my regular soap (giving this a little dwell time on the wheels), then I use a soft brush on the wheels and a medium brush on the tires, before power washing everything. It keeps my wheels clean and degreases my tires for dressing application. It's good stuff thar makes quick work of the worst part of car washing.

This wheel cleaner requires no scrubbing it works so great! I spray it on and rinse it off with the pressure washer. This is a huge time saver cleaning all the dirt and grime out of the rims and is definitely worth the money. I would highly recommend this product if you’re looking for a wheel cleaner that actually works without having to scrub hard!

I had high hopes for the Koch Chemie wheel cleaner based on the description and reviews. While it’s better than a lot of other wheel cleaners I’ve tried, it doesn’t fully live up to the hype.I found that I had to apply it multiple times to get my wheels properly clean, especially if there was heavier brake dust or grime. It definitely helps loosen dirt, but it’s not the powerful, one-spray solution it’s advertised to be.Overall, it’s a decent cleaner and a bit better than many other options out there — just don’t expect a perfect result with one application.

This stuff works great in a foamer to remove tire browning!
