Comprehensive Iron Fallout Decontamination and Removal

Ensure the vehicle panels are cool to the touch (ideally below 30°C). In Australian summer conditions, this usually requires working inside a garage or under a professional gazebo. Never apply iron remover to a panel that has been sitting in the sun, as the chemical will flash-dry instantly, potentially etching the clear coat or leaving permanent streaks.

Perform a comprehensive pre-wash using snow foam to remove loose grit, followed by a two-bucket contact wash. Use a high-alkaline 'strip wash' shampoo if possible to remove existing waxes. This ensures the iron remover makes direct contact with the embedded particles rather than being blocked by surface contaminants or old protection layers.

Use a dedicated drying towel or air blower to remove approximately 80-90% of standing water. While some iron removers can be used on wet cars, excess water dilutes the formula, reducing its effectiveness and increasing the 'run-off' rate, which wastes expensive product.

Don nitrile gloves and eye protection. Iron removers have a potent sulphur-like smell that can be overwhelming in enclosed spaces. Ensure your workspace has high airflow. If working in a garage, use a pedestal fan to move fumes away from your breathing zone.

Work one panel at a time, or 2-3 panels if working in a temperature-controlled environment. Spray the iron remover generously over the surface, starting from the bottom of the panel and working upwards. This 'bottom-up' approach prevents 'run-down' streaks from forming on dry paint.

Allow the product to dwell for 3 to 5 minutes. You will observe a 'bleeding' effect where the clear liquid turns deep purple or red as it reacts with iron oxide. In high-humidity coastal areas, the reaction may happen faster. Do not allow the product to dry on the surface.

For heavily contaminated vehicles, use a damp microfibre applicator or a soft detailing brush to gently agitate the product while it is still purple. This helps the chemical penetrate deeper into the 'root' of the iron shard embedded in the paint.

Rinse the panel thoroughly with a high-pressure washer. Pay close attention to window seals, door handles, and badges where the chemical can hide. Continue rinsing until the water runs completely clear and no purple residue remains.

While the car is still wet, apply a dedicated clay lubricant to a 50cm x 50cm area. Using a fine-grade clay bar or mitt, glide the tool over the surface using light finger pressure only. You will feel and hear the clay 'grabbing' at the remaining contaminants.

Work in a cross-hatch pattern (up-down, then left-right). Continue until the clay glides silently and smoothly over the panel. This removes non-ferrous contaminants like industrial overspray, tree sap, and stubborn bug remains that the iron remover cannot dissolve.

If using a traditional clay bar, fold the bar frequently to reveal a fresh, clean surface. If using a clay mitt, rinse it in a bucket of clean water after every panel to dislodge trapped particles and prevent scratching.

Perform a final high-pressure rinse of the entire vehicle to remove any clay lubricant residue or dislodged particles. Dry the vehicle completely using a clean microfibre towel or air dryer.

Place your hand inside a thin plastic sandwich bag and lightly run your fingertips over the dry paint. The bag amplifies any remaining imperfections. If the surface feels like glass, decontamination is successful. If it still feels gritty, repeat the process on those specific areas.

Decontamination leaves the paint 'naked' and unprotected. It is critical to apply a sealant, wax, or ceramic coating immediately after this process to prevent the freshly cleaned pores of the paint from becoming re-contaminated or oxidising under UV exposure.
