This is hands down the best no-effort wheel cleaner I have ever used. Most products claim you can just spray them on and rinse them off, but you usually need a brush to agitate the entire wheel before seeing any results. With the Reactive Wheel Cleaner, I can literally pressure wash the wheel, apply the product liberally, and watch it remove every last speck of dirt without a brush. It even turns red once the process is complete—it couldn’t be easier.
