Dish soap: You can use a mild dish soap, such as Dawn or Ivory, as an alternative to car wash soap. Be sure to dilute the soap in a bucket of water to prevent it from being too harsh on your car’s paint.
Laundry detergent: Another option is to use a mild laundry detergent, such as Woolite or a similar brand. Again, be sure to dilute the detergent in a bucket of water.
Baking soda: Baking soda can be used as a gentle abrasive to clean your car. Mix baking soda with water to make a paste, and use a sponge or cloth to apply it to the surface of your car. Rinse thoroughly with water.
Vinegar: Vinegar can be used to clean your car’s windows and remove water spots. Mix equal parts water and vinegar in a spray bottle and apply to the windows. Wipe clean with a microfiber towel.
It’s important to note that while these alternatives can be effective at cleaning your car, they may not provide the same level of protection as car wash soap. If you’re concerned about protecting your car’s paint, it’s best to use a soap specifically designed for cars.
