With more people choosing to wash their cars at home to save time and money, experts warn that improper cleaning methods can do more harm than good. Small mistakes during a home car wash can damage the paint, reduce shine, and even lower the vehicle’s resale value.

One of the most common errors is using household cleaning products such as dishwashing liquid, laundry detergent, or even hair shampoo. These substances contain harsh chemicals not meant for automotive surfaces and can gradually strip away the protective paint layer. Similarly, DIY solutions like lemon, vinegar, or baking soda may remove dirt initially but can lead to micro-scratches and increase the risk of rust over time. Experts recommend using only car-specific shampoo for safe cleaning.

Another frequent mistake is washing the car under direct sunlight. When water dries too quickly, it leaves behind stubborn water spots that dull the finish. The choice of cleaning material also plays a crucial role. Old clothes or towels may seem soft but often trap dust particles, which can scratch the car’s surface—especially visible on darker colours.

For best results, it is advisable to follow a proper cleaning sequence. Start with the tyres and underbody, where dirt accumulation is highest, and then move upward to the body and roof. Using a microfiber cloth or a soft sponge helps prevent scratches and preserves the paint quality.

Modern vehicles come with multi-layer paint coatings that require careful maintenance. Repeated improper washing can wear down this protective layer. By adopting the right techniques and using suitable products, car owners can maintain both the shine and long-term value of their vehicles.
