Is it good to wash a car in the rain?

The thought of washing your dazzling car in the rain may make you skeptical.  While it may seem beneficial to some, it also comes with potential risks.

Many people believe that allowing rain to wash their cars naturally saves time, money, and water. However, this approach is not always practical; it can dull the car’s shine and damage its surface over time.

Read this blog to find out whether washing your car in the rain will be a helpful solution or a hidden hazard in the long run.

Why Do People Believe Washing Cars in the Rain Is Beneficial?

Natural wash with rainwater: Rainwater effectively washes the surface of your car and loosens the long-accumulated dirt and debris.

Eco-friendly and cost-effective way: Park your car outside in an open space and let the rain act as a natural, eco-friendly alternative to traditional washing. This also conserves water, making it an added environmental benefit.

Convenience: The rainy season in Canada provides an opportunity for car owners to wash their vehicles conveniently. After rainwater softens dirt, you can follow the usual process: shampoo with a pH-neutral product, rinse with clean water, and pat dry with a microfiber towel.

Why washing a car in the rain is not always a good idea

Concerns associated with acid rain: Rain often contains environmental pollutants such as debris and dirt particles collected from the air, commonly referred to as acid rain. This can be harmful to your car’s paintwork and may cause significant surface damage.

Risk of water spots and streaks: Rainwater droplets inevitably create water spots and streaks on the car’s surface, which can make it appear dirty and damaged.

Ineffective cleaning: Rainwater alone does not effectively clean your car’s surface; it simply wets it. Without physical effort, it cannot remove marks, stains, grease, or grime. Furthermore, mud stains can splash onto the car when rainwater hits roads or flat surfaces.

Cold Weather Risks: In cold regions of Canada, washing your car in the rain is not advisable, as water can freeze and damage the car’s exterior.

Does Not Provide Protection: High-quality products are used to ensure the safety of the car’s paintwork, but washing the car in rainwater does not provide any protection and can even cause damage.

When is washing in the rain most effective?

Light to moderate rain: Washing your car during light to moderate rain is more effective than during heavy rain.

Drying time matters: After washing your car in the rain, dry it immediately to prevent water spots and streaks.

Use the right products: Enhance the cleaning process by using high-quality products like pH-neutral shampoo or specialized car cleaners.

Check the weather: If the rain seems more polluting and acidic, avoid washing your car to prevent severe damage. Always check the weather forecast in your area beforehand.

How to wash your car in the rain

There is no strict rule for washing your car in the rain, but there are a few simple steps you should carefully follow for the best results.

Pre-rinse: Let the rainwater naturally soak the car’s surface for a few minutes. Then, use a car wash mitt to gently remove grime, bird droppings, and other debris.

Use of soap: Apply specially formulated products like pH-neutral soap, shampoo, or cleaners to effectively clean the car’s surface.

Cleaning:  Clean the car section by section, applying and removing products to ensure thorough cleaning.

Drying process: Use high-quality microfiber towels to dry the car. Use an upward and pat-drying technique to prevent water spots and streaks.

Protective coating layer: Finish by applying a layer of wax or sealant to the car’s surface to protect the paint and secure prolonged polish.

Why is car washing important after rain?

Rainwater is naturally acidic, which can severely damage your car’s clear coat, leading to rust and corrosion. It also causes environmental pollutants to accumulate on the surface. To prevent these issues and maintain your car’s value, lifespan, and shine, expert detailers recommend washing your car immediately after rain.

In Conclusion

Washing your car with rainwater has both benefits and drawbacks.  If you choose to wash your car in the rain, it’s essential to use the right tools, products, and post-wash care techniques, as prevention is always better than repair.
