1. Reasons for oxidation of automobile wheels
1. The surface is scratched by a hard object. At this time, the air can directly contact the aluminum and oxidize at the injured part first. In the future, the oxidation will gradually spread to the surrounding area.
2. Wheel hub oxidation is often caused by corrosion by corrosive chemical products.
Nowadays, after washing the car, the general car wash shop will help to brush the tires for free. After the brushing, the tires are shiny and beautiful. But once this kind of thing is brushed on, it will often corrode the tire and wheel hub, and even affect the performance of the tire, causing the wheel hub to become yellow and oxidized. Seeing them brushing free tire wax, they must stop immediately.
2. How to solve wheel oxidation
Preparation: 1 bottle of toilet cleaner, 1 large brush, 2 used toothbrushes, 1 bucket, and 1 tap water source.
Cleaning:
1. Receiving water in a bucket.
2. Use clean water to clean the dust on the surface of the wheel hub first.
3. Use toilet cleaner to dilute the black and yellow dirt on the surface, and scrub the edges and corners with a waste toothbrush.
4. After cleaning with clean water, all the black and yellow dirt is removed except for the wheel hub which cannot be cleaned due to wear and tear. I am very satisfied.
The wheels are wiped with a wet sponge, so that the start-up process will remove most of the remaining brake dust and dirt, and prevent the scrubbing surface from scratching the wheels.
Remove dust and debris from the store to buy clean aluminum alloy wheels, avoid acidic cleaners. Mix an appropriate amount of water and detergent in a bucket. Soak the sponge in a bucket of detergent and water. Squeeze the sponge bucket to avoid wasting detergent. Scrub the wheels with a sponge.
Third, the daily maintenance of the wheel hub
1. Scratch treatment of wheel hub
In the process of long-term use of a car, it is inevitable that there will be various scratches on the wheel hub. The treatment of these scratches is generally divided into six steps:The first step is to check the scar. If there is no damage to the inner side of the wheel hub, you can simply repair it. Use paint thinner to wipe around the scar to remove dirt;
In the second step, it is difficult to remove the dirt on the deepest part of the scratch. At this time, you can use a toothpick to clean it thoroughly;Step 3: In order to prevent unrelated parts from being painted with paint by mistake, it is best to carefully stick the adhesive tape around the scar;The fourth step is to arrange the tip of the brush and apply the finishing paint. The paint will shrink slightly after drying, and it is best to paint it slightly protruding;The fifth step, after painting, it takes about a week to dry completely. After drying, apply water-resistant paper dipped in soapy water to smooth the surface;The sixth step, after wiping with water-resistant paper, wipe out the light with the mixture, and then wax.
2. If you encounter a deep scar, the key point is to observe whether the metal surface is exposed. If the metal surface is not visible, it will not rust. You can concentrate on applying the finishing paint. Use the tip of the pen to go up little by little, and then wait for the paint to dry completely. To avoid such a phenomenon, the car should be diligent to wash the rim when it is first used. Generally speaking, the rim should be washed at least once a week. Then rinse with plenty of water.
3. Daily maintenance can not be ignored
Daily maintenance is also indispensable. When the temperature of the wheel hub is high, it should be allowed to cool down before cleaning. Never use cold water to clean it; otherwise, it will damage the aluminum alloy wheel hub and even deform the brake disc. And affect the braking effect. In addition, cleaning the aluminum alloy wheels with detergent at high temperatures will cause chemical reactions on the surface of the wheels, loss of luster, and affect the appearance.
4. When there is hard-to-clean asphalt on the wheel hub. If the general cleaning agent does not help, you can use medicinal "activating oil" to wipe it, and you can get unexpected results. Car owners may wish to give it a try.The copyright belongs to the author Website of China wheels
