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

1. Strip off wax and sealant

• Dawn is a powerful degreaser designed to remove grease and grime, which means it can remove any wax or sealant you’ve put on your car’s paint. This leaves your paint unprotected and more susceptible to damage from environmental factors.

2. Strict requirements for paint

• The formula of dish soap such as Dawn may be too harsh for car paint. Over time, regular use can cause sluggishness and potential damage.

3. pH Balance

• Car wash soap is specially formulated to be pH balanced to help maintain the integrity of the paint and any protective coatings. Dish soap does not have this balance and may cause problems with the paint finish.

Recommended alternatives

• Use Car Wash Soap: It is best to use soap specifically designed for car washing. These products are formulated to clean effectively without damaging paint or stripping wax.
• pH Balanced Products: Look for a pH balanced car wash soap that is gentle on paint and safe for regular use.

in conclusion

While the occasional use of Dawn soap in a pinch may not cause immediate harm, it’s best to avoid using it in a regular car wash. Choose a specialized car wash soap to ensure the longevity and appearance of your vehicle’s paint.
