You can apply toothpaste to a damp towel and then rub it back and forth on the area with rust stains. After cleaning, let it dry; You can apply essential balm to the rust stain, wait for five minutes, and then wipe it with a damp towel; If the area is not very large and the adhesion is not very high, simply add water and sand it; if the area is too large and the adhesion is high, you will need to repair the car body.
I've been driving for many years, and recently noticed some rust spots under the car, which initially worried me. Following online video instructions: first thoroughly rinse the rusty areas with car wash tools, especially around the wheels and chassis where mud and water tend to accumulate. Then gently sand off the rust powder with fine sandpaper, being careful not to damage the original paint. After sanding, wipe it dry and apply a layer of rust-proof paint or spray a rust inhibitor like WD-40 available on the market. Wait until it's dry before driving. For regular maintenance, I make it a habit to wash the car once a week, more frequently during the rainy season, and always dry it afterward to avoid water stains. Leaving rust untreated can lead to spreading, corroding the metal structure, affecting safety and appearance. Tackling minor issues yourself saves worry and money, and it's a good way to practice skills, but for severe rust, it's best to consult a professional repair shop.
I'm quite passionate about car maintenance and always want to understand the causes when I spot rust. The most common reason is damaged paint exposing metal, combined with moisture corrosion. I've tried the treatment process: first clean the rust spots to remove dirt, then carefully sand them smooth without damaging the original paint. After that, apply anti-rust primer to protect the metal, and finally use spray paint to restore the color. Nowadays, nano-coating technology makes it more convenient - just spray anti-rust agent once to get it done. For prevention, I recommend checking the car body monthly, especially corners and wheel arches, and applying some car wax to isolate air and moisture. Extra attention is needed in high-salt areas as corrosion can weaken the frame strength and threaten driving safety. When doing it yourself, wear gloves and ensure ventilation - basic tools like sandpaper and brushes are enough. Normally, avoid driving through waterlogged roads and maintain a dry environment.
