So one of our most popular products is "Purple Rain" wheel cleaner. It is a basic "fallout remover" that reacts with iron deposits that are left by your brake dust on wheels.
We released a few other videos showing the product in action but people seem to claim that the cleaning was being done by the pressure washer more than the purple rain wheel cleaner.
So we made this comparison video.

Brake dust can be especially difficult to remove if left on the wheels for a while, so the purple rain wheel cleaner helps to make the cleaning process much faster.
Test 1) We pressure wash the wheel. Then apply the Purple Rain and leave it soak for 4 minutes to react with the iron. Then we pressure wash the product off.
Test 2) We use a normal hose without pressure to rinse the wheel. Then apply the Purple Rain and leave it soak for 4 minutes to react with the iron. Then we rinse the product off without the use of a pressure washer.
Things to note: NO this product doesn't magically clean "dirty" wheels. If your wheels are covered in road grime, then the product will ONLY react with the iron brake deposits.
Normal dirt will need to be addressed with either an acidic or soapy wheel cleaner, along with a pressure washer, or good old fashioned elbow grease.
You will notice after test 2 that there is still some traces of road grime, however they wipe off easily with a finger.
Hopefully this comparison helps put some of the arguments to rest :)
