Q: How can I remove the “caked-on,” black dirt that collects on my wheels?
A: Along with road dirt, what you are seeing is accumulated brake dust. The old method for removal usually involved scrubbing for hours with a toothbrush.
Today, you can use ARMOR ALL® Wheel Cleaner, which safely loosens brake dust and wheel soil on most types of wheels, allowing it to be rinsed away with a spray of your hose.
Before use, read precautions on product label.
