Experience the future of wheel decon with Iron Wheel Gel. Iron Wheel Gel is formulated to create a thick gel-like viscosity to dwell on the wheel, allowing it to work longer. The strong ph-neutral formula reacts with the iron, turning it purple. Allow 2-5 minutes of dwell time and flush off, and without the unpleasant sulfur smell that permeates and lingers in your work environment, and on your clothes and skin!
