Australia's wet season may bring cooler temps and greener landscapes, but it also means mud, grime, and water spots on your car. Many drivers assume there's no point in washing their vehicle during the rain — but this is actually the most important time to keep your car clean.

In this guide, Accura Cars shares pro-level wet season car wash tips to protect your vehicle, maintain its shine, and extend its lifespan — whether you drive daily or rent one of our cars in Perth.

Why Car Care Matters in the Rain

Rain doesn’t just make your car wet — it often deposits acidic contaminants, road oil, and grime onto your paintwork. If not washed off regularly, these substances can:

• Damage your paint and clear coat
• Cause rust and corrosion (especially underneath)
• Create permanent water spots

So, even during Australia’s wet season, regular washing is critical to maintaining your vehicle’s value and appearance.

Top Wet Season Car Wash Tips

1. Wash After Heavy Rain, Not Just Before

Rain doesn’t “clean” your car — it spreads contaminants. Washing after rainfall ensures pollutants are removed before they etch into your paint.

2. Use a Quality pH-Balanced Car Shampoo

Always use a pH-neutral car wash product. Dish soaps and cheap cleaners strip away wax and protective coatings.

Bonus Tip: Choose a shampoo with wax additives for extra shine and hydrophobic protection.

3. Focus on the Undercarriage and Wheel Arches

Mud, gravel, and road salt collect under your car during wet weather. These areas are rust-prone and often ignored.

Use a pressure washer or underbody sprayer to clean:

• Suspension components
• Brake lines
• Wheel wells

4. Apply a Hydrophobic Wax or Ceramic Coating

Before or during the wet season, apply a protective wax or ceramic coating to make water bead off your paint. It helps:

• Prevent water spots
• Reduce grime buildup
• Make future washes easier

5. Dry Your Car Properly – Even in Rain

Drying your car after washing — even on cloudy or rainy days — prevents:

• Water spots
• Streaking
• Mould and mildew in door jambs

Use a microfiber drying towel or air blower for best results.

6. Clean Your Wipers and Windshield

In wet season driving, clear visibility is a must. Keep your wipers and windshield grime-free to prevent smearing.

Use:

• Glass cleaner with rain-repellent properties
• A damp microfiber cloth to wipe wiper blades weekly

7. Don’t Neglect the Interior

Wet shoes, umbrellas, and humidity can wreak havoc inside your car too. Protect your interior with:

• Rubber mats
• Quick-drying fabric protectant
• Frequent vacuuming
