Your car catches tiny bits of metal from road grime, train tracks, and brake pads. These particles stick hard to your car and normal soap cannot remove them. That's where Witch's Brew comes in. Iron removers use special chemicals that react with the metal on your vehicle. The chemical turns the metal into a purple liquid form so you can rinse it away safely.

Decontaminating (decon) a surface before buffing removes embedded dirt, iron particles, and old waxes. If you skip this, your buffing pad will pick up the trapped debris. The pad then drags this debris across the paint, creating deep scratches. Cleaning the surface before this process ensures a flawless, smooth finish.
