The Australian wet season can be tough on your car. Constant rain, road grime, and mud not only affect your car’s appearance but also compromise its long-term value. Many drivers assume rain will "clean" their vehicle — but in reality, rainwater carries dirt and acidic pollutants that can damage your paint over time.

In this guide, Accura Cars shares the top rainy season car wash tips for Australian drivers, helping you maintain your vehicle through every storm — whether you're renting, owning, or detailing.

1. Don’t Skip Washing Just Because It’s Raining

One of the biggest myths in car care is that rain naturally cleans your car. In fact, rainwater in urban areas contains acidic contaminants that can etch into your paint and leave water spots if left uncleaned.

✅ Tip: Wash your car regularly even during the rainy season to protect the clear coat.

2. Use a pH-Neutral Car Shampoo

When cleaning your car during the wet season, avoid dish soaps or generic detergents — they strip wax and harm paint.

✅ Use a pH-neutral car shampoo specifically designed for Australian car detailing in wet weather.

3. Apply a Hydrophobic Wax or Ceramic Coating

Applying a protective layer helps water bead off the car’s surface, reducing water spots and grime buildup.

✅ Look for ceramic coatings or wet-season waxes for long-lasting protection during heavy rains.

4. Focus on Wheel Wells and Undercarriage

During rain, mud and grime collect in your car’s undercarriage and wheel wells — areas often missed during casual washes.

✅ Use a pressure washer or underbody rinse tool to remove salt, grit, and sand from these critical spots.

Why it matters: Prevents corrosion and prolongs the life of brake and suspension systems.

5. Don’t Forget Your Windows and Mirrors

Clean and streak-free windows are essential for safe driving in rainy conditions. Use glass cleaner with rain-repelling technology to ensure better visibility.

✅ Apply Rain-X or similar repellents to your windscreen and mirrors.

6. Dry Your Car After Washing – Even in Rain

Leaving water on the surface can lead to spotting and staining, especially during humid or wet seasons.

✅ Use a microfiber towel or soft drying blade. Avoid air drying or letting the rain handle it.

7. DIY vs Professional Car Wash – What’s Better in Rain?

While DIY washes are great for maintenance, the rainy season may call for professional detailing, especially for ceramic coating or deep cleans.

✅ Accura Cars recommends regular professional car washes during rainy months if you don’t have a covered wash area.

Bonus Tip: Protect Your Car Interior Too

• Use rubber floor mats to keep wet and muddy shoes from ruining your carpets.
• Keep microfiber cloths handy for foggy windows and mirrors.
• Consider applying a fabric guard to your seats to prevent water stains.
