What cleaning agent should be used for DIY car washing?
3 Answers
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.
I always wash my car myself and have tried several cleaning agents. I find that dedicated neutral car wash liquids, like those from Turtle Wax or Meguiar's, are the most reliable. They are gentle on the paint, produce rich foam, and easily remove stains. When washing, first rinse off the dust with soft water, then pour the car wash liquid into a bucket, dilute it, and gently scrub the car body with a sponge or soft brush. For the wheels, it's best to use a dedicated wheel cleaner to avoid rust. After rinsing, dry the car with a soft towel and avoid leaving it under direct sunlight to prevent water spots. The key is that the neutral formula protects the wax layer and extends the paint's lifespan. I also regularly apply wax for extra protection. The whole process is simple and affordable—just 20 minutes—and much cheaper than going to a car wash.
Choosing the right car wash detergent for DIY car washing requires some attention. I primarily focus on the ingredients and pH level—neutral or slightly acidic solutions are the safest and won’t corrode the paint. Commercially available car-specific wash solutions often contain protective agents that help maintain the shine longer. While household dish soap can be used in a pinch, its high alkalinity can damage the paint if used frequently, so it’s best to avoid regular use. The washing process should follow these steps: first rinse the car body, then apply the car wash solution evenly and scrub gently, avoiding direct high-pressure water spray on the paint. Opt for a soft sponge instead of hard brushes, and dry the car immediately after washing to prevent water spots. Additionally, consider the surface material—use a dedicated glass cleaner for windows to ensure streak-free clarity. Following this comprehensive approach ensures efficiency while minimizing potential damage.
