Many people wonder, “Can you use laundry detergent to wash a car?” The short answer is: It’s not recommended. Laundry detergents are formulated for fabrics, not painted surfaces, and often contain harsh chemicals, degreasers, and fragrances that can strip away the protective wax on your car and lead to fading, etching, or dullness over time.A dedicated car wash soap is specially formulated with balanced pH and gentle cleaning agents that effectively remove dirt and grime while preserving your car’s finish. These products are designed to rinse away cleanly, leaving behind no residue that could attract more dirt. Using laundry detergent may save money in the short term, but you could end up spending much more to repair damage to your paintwork or clear coat.As a designer, I’m always considering not just what looks good today, but how materials and finishes age over time. Similarly, when choosing cleaning supplies for a project—whether it’s interior furnishings or your car’s exterior—selecting the right product guards the investment you’ve made in quality materials and thoughtful design. If you’re passionate about your car’s appearance, I recommend using tools that make the process as efficient and safe as possible.
