How to Remove Iron Particles?
3 Answers
After iron particles accumulate on the vehicle, it is necessary to take it to a professional car wash for cleaning. Below is relevant information about automotive iron particles: 1. Causes of formation: When driving, the vehicle body generates static electricity that attracts particulate matter from the air, including iron particles. Parking near construction sites or factories can also lead to iron particle accumulation. Additionally, iron particles are produced from brake disc wear during braking. Japanese cars directly discharge iron particles into the air. These particles are also easily attracted to the car paint while driving. 2. Hazards of iron particles: Iron particles on the paint surface will adhere to the car's surface as moisture evaporates. Once oxidized, they turn into yellowish-brown rust spots. The iron particles will continuously spread and oxidize the surrounding paint, eventually penetrating the topcoat and oxidizing the underlying metal. Alternatively, high speeds or engine heat can soften the paint, allowing the particles to embed themselves. Once iron particles fuse with the paint, the damage progresses from the surface inward, gradually causing the paint to lose its luster, discolor, and form "psoriasis-like" blemishes. The paint may deteriorate, making maintenance extremely difficult. In severe cases, the paint may peel or flake off, becoming irreparable.
Last time I helped my neighbor deal with those rusty yellow spots on the car wheels, I specifically bought a bottle of iron remover. Spray it on the yellowed rims, and it's quite magical to see the liquid turn purple. Just let it sit for five minutes, then scrub with a stiff brush and rinse off. For stubborn areas, using detailing clay back and forth works exceptionally well. Remember to wear gloves when handling this stuff—it's harsh on the skin. If you can't manage it yourself, spending some money to go to a professional wheel repair shop is more worry-free. They have specialized equipment and can also handle brake dust stains baked onto the rims.
Professional iron particle removal actually involves two steps: softening and rinsing. First, spray tar remover on the wheel surface and let it sit for three minutes. After the rust reacts and loosens, rinse it with a low-pressure water gun, then dry it with a microfiber cloth. Pay special attention to the back of the spokes and screw holes, as these dead spots are prone to dust accumulation. Never use a steel wool pad during the process, as it can scratch aluminum alloy wheels. Doing this every three months can prevent brake dust sintering, and car wash shops usually charge around 80 yuan for this service.
