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.

Worked great and really attacked the brake dust!

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.

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.

Get it

What else would you expect from a Koch Chemie excellent product & at a great value.

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

I saw a video on Instagram where a detailer said this was THE BEST wheel cleaner for BMW M model wheels and I’ve been trying to find something I love so I decided to give it a try.I followed the instructions and diluted the product 2:1, their strongest suggested dilution. The face of the wheels came clean where I used a brush/sponge and pressure washer. Sadly the area where a brush can’t touch did not come clean. I have purchased other products on Amazon that are less expensive that at least get those areas clean.So in short, it works ok, but not for the cost.
