It is generally not recommended to use Dawn dish soap to wash your car. Here are some reasons:

1. Paint Roughness:

• Dawn is designed to remove grease and grime, which makes it effective for tableware, but too harsh for car paint. It can strip the car’s surface of protective wax or sealant, leaving the paint vulnerable to damage.

2. pH Balance:

• Automotive soap is specially formulated to be pH balanced to help maintain the integrity of paint and varnish. Dawn’s pH is not balanced, which can cause dullness or damage over time.

3. Possibility of vortex traces:

• The abrasive nature of dish soap can create micro-scratches or swirl marks on the paint, especially if the wrong cleaning technique or tools are used.

4. Residue:

• Dawn leaves a residue that may attract dust and dirt, making your car look dirty soon after washing.

in conclusion

For best results and to protect your vehicle’s paint, it is recommended to use a specialized car wash soap formulated specifically for automotive use. These products are designed to clean effectively while gently protecting your car’s paint and protective coatings.
