What cleaning agents are needed for washing a car by yourself?

When washing a car by yourself, you need to use specialized car cleaning agents. The precautions for car washing are: 1. Avoid using alkaline substances such as laundry detergent or dishwashing liquid to wash the car; 2. Rinse the vehicle promptly after rain or snow; 3. Avoid washing the car under direct sunlight; 4. Use a dedicated car washing cloth to wipe from top to bottom along the direction of water flow; 5. Wash the car after the engine has cooled down. The effects of not washing the car regularly are: 1. Accumulated dust affects the car's appearance and the owner's image; 2. Bird droppings, tree sap, and insect residues can continuously corrode the paint surface, causing the car paint to age, fade, or even crack; 3. Acidic substances in rainwater and air can oxidize and corrode the car's metal, leading to premature damage.
Choosing the right cleaner is crucial when washing your car yourself. First, opt for a pH-neutral dedicated car wash solution, such as Turtle Wax or Meguiar's—avoid household dish soap as its high alkalinity can dull the paint after just a few washes. Using a foam cannon (PA壶) when applying soap enhances results by softening dirt and preventing scratches. For wheels, use a dedicated metal cleaner since brake dust is highly corrosive and regular car wash soap won’t remove it completely. Use alcohol-free glass cleaner for windows to ensure clear visibility during rain. After washing, apply an iron remover spray; road iron particles will turn purple upon contact and rinse off, leaving the paint smooth to the touch. Finally, dry the car with a microfiber towel to avoid water spots.
The biggest fear when washing your car yourself is damaging the paint. I've specifically researched cleaning agents. The key is to choose a water-activated formula—it automatically breaks down dirt when rinsed with tap water, saving effort. Avoid car wash liquids containing wax for the body, as they can affect the later waxing effect; opt for a basic version labeled 'no additives.' For wheel cleaning, choose a foam-type cleaner—spray it on, let it sit for two minutes, then scrub, and oil stains and brake dust will rinse right off. Don't forget to buy a tar remover for asphalt spots; just apply it to small areas. Washing windows requires attention—cleaners with ammonia can leave white fog, so choose one with surfactants for more clarity.
