What cleaning agent should be used for DIY car washing?

[Lamar]

Car washing should use specialized automotive cleaning agents. There are brands like Turtle Wax and Red Power available on the market. When purchasing, ensure the cleaning agent is pH-neutral. Neutral cleaning agents protect the car paint from damage during washing, are gentle on the skin, and often contain wax components that help preserve the paint surface. Remember, never use laundry detergent as a substitute for car cleaning agents, as laundry detergents are alkaline and can corrode the car paint. More details are as follows: Do not randomly clean the engine compartment: Because the engine compartment is filled with components like circuit boards, carelessness can easily damage high-voltage packs and circuit boards. Therefore, be extra cautious when washing the car yourself, especially avoiding the use of high-pressure water jets. Cleaning frequency: There's no need to wash the car too frequently; once a week is recommended. For general dust, gently sweeping with a feather duster or a soft-bristled broom is sufficient. However, if the car encounters heavy rain, mud, or severe dust, it should be cleaned promptly.
