Oberk 2-in-1 Wheel Cleaner is pH neutral, using an advanced chemical formulation for removing iron particles and excessive brake dust without the risk of damaging the most delicate wheel finishes. With a thicker viscosity, Oberk 2-in-1 wheel cleaner clings to the vertical surfaces of the wheel while retaining a foamy mixture of cleaners to lift and remove every day contaminants picked up from the road or your vehicles braking system. Oberk 2-in-1 wheel cleaner is safe for use on all painted surfaces, plastics and more, but it was developed to fill the void between new iron removing technology and traditional foaming wheel cleaners. Product Note: The 128 oz. gallon product does not come with an individual spray bottle. Directions to Use We recommend the vehicle being in the shade and the paint cool to touch. Applying to hot paint or direct sunlight can cause drying, water spots and short work time. Oberk wheel cleaner is safe for all finishes but retains the cleaning power to remove iron as well as clean heavy road debris. The clinging formula changes color to show when it is reacting with iron particles and sticks to vertical surfaces for extended dwell and cleaning time. Spray 2-1 Oberk wheel cleaner on a DRY wheel surface and let dwell. Wheel surface can be wet, but spraying directly on dry surface will maximize efficiency and effectiveness of iron removing. Brush wheel face and barrel surface, then rinse clean. Follow with defense gel for premium wheel protection and dry with the wheely dry towel or blower.
