In conclusion, washing your car correctly is essential to maintaining its paint and appearance. Avoid using laundry detergent, as it can damage the paint and leave your car unprotected. Instead, use car-safe soap, rinse thoroughly, and dry carefully with a microfiber towel. By following the right steps, you ensure your car stays clean without any damage to the paint. So next time you ask, "Can I wash my car with laundry detergent?" remember that the answer is no—always use products designed for automotive care.
