Methods for removing grease spots from the car are as follows: 1. If the grease spots haven't been there for long: If detected early, they can be wiped off directly with a cloth. 2. If the grease spots have been there for a long time: If the grease has been present for an extended period, causing wrinkles, bubbling, or cracking on the paint surface, it is necessary to use automotive-specific cleaning sandpaper to remove the grease, followed by waxing to restore the car's shine. Below are some precautions for car washing: 1. Frequency of washing: Under normal circumstances, washing the car once every 1-2 weeks is standard. 2. Wash as needed: Since each car is parked in different environments, some cars, apart from being driven on the road, are mostly parked in underground garages and may remain clean for up to a month in good weather; many cars parked outdoors usually accumulate a layer of dust within two weeks. Therefore, the frequency of washing will vary depending on the vehicle. 3. Cleaning agents and tools: First, ensure that the cleaning agent used is neutral, as acidic or alkaline ones can corrode the car paint to some extent. For washing tools, especially the towel used for the car body, it is essential to use a special pure cotton car-washing towel to avoid scratching the paint. 4. Wash the car after rain: Due to current environmental pollution, rainwater often contains acidic substances, so it's advisable to clean it off as soon as possible. If there are stains or mud on the car, it's also recommended to wash them off promptly to prevent corrosion and oxidation of the paint. 5. Regular paint maintenance: Maintenance treatments for the car paint surface generally include waxing and glazing. Glazing is slightly more effective than waxing, lasts longer, and is also more expensive.
