Koch Chemie Alkali Wheel Cleaner Awh

Koch Chemie Alkali Wheel Cleaner Awh, as the name suggests, utilizes the alkaline end of the pH spectrum to lift dirt off of your wheels. 

I had an advanced sample to test before release, and started using it at full blast (because winter in New Hampshire). This stuff EATS, does a very nice job of removing all the gunk built up from the brakes as well as everything that attached itself from the roadways. Under normal conditions, I would suggest knocking this back with water at a rate of 1:10 for general wheel cleaning, but you can use a dilution of 1:2 if it's a really grubby set.

During application, you want to rely on the chemical instead of dwell time. That means spray on, brush the surface, and rinse off before moving to the next wheel. If you have a spot that requires more cleaning, spray more instead of letting the initial application sit. Just like an acid, you keep this 'wet work'. I am far more comfortable with an iron remover drying on a set of wheels than acidic or alkaline cleaners as they will mark. KNOW YOUR PRODUCTS, KNOW YOUR PROCESS.

Alkaline tends to mist and fog when sprayed, can get foamy, but Awh seems to do that less than others in this category. 

Finish the work by completely rinsing the wheel, tire, as well as the ground it sits on so runoff does not mark the pavement etc.
