How to Wash a Car with Ceramic Coating

Ceramic Coated Vehicle? Here's How to Wash It.

A ceramic coating provides long-lasting protection for your car’s paint, making it resistant to dirt, water, and minor scratches. However, maintaining its effectiveness requires proper washing techniques. Unlike traditional waxed surfaces, ceramic-coated cars need special care to ensure the coating remains intact and continues to perform at its best.

This guide covers the best practices for safely washing a ceramic-coated vehicle while preserving its hydrophobic properties and  finish.

After reading this article, you may decide that it would be better to have your car professionally washed. Take a look at our detailing packages! We also offer subscription plans through our Supreme VIP program that saves you money and keeps your car perfectly cleaned year-round.

Wash Using the Two-Bucket Method

The two-bucket wash method is the safest and most effective way to clean a ceramic-coated vehicle while preventing swirl marks and scratches.

Why Use the Two-Bucket Method?

Prevents dirt and debris from being rubbed back onto the car.

Maintains the hydrophobic properties of the ceramic coating.

Reduces swirl marks and scratches that can dull the finish.

Ensures a effective and safer wash for long-term paint protection.

What You’ll Need

Using the right tools and products when washing your vehicle is essential for preserving the integrity of your ceramic coating.

  • Two buckets (one for clean water, one for soapy water).
  • Grit guards for each bucket (traps dirt at the bottom to prevent contamination).
  • pH-neutral, ceramic-safe car shampoo (ensures the coating isn’t stripped).
  • Microfiber wash mitt (gentle and safe for ceramic-coated surfaces).
  • Soft microfiber drying towels or touchless air blower (prevents swirl marks and water spots).

Step-by-Step Guide to Washing a Ceramic-Coated Car

1. Set Up Your Buckets

  • Fill Bucket #1 with clean water and add ceramic-safe car shampoo.
  • Fill Bucket #2 with plain water for rinsing your wash mitt.
  • Place a grit guard in each bucket to trap dirt and debris at the bottom.

2. Pre-Rinse the Car

  • Use a pressure washer or garden hose to remove loose dirt, dust, and debris.
  • Start from the roof and work your way down, ensuring the dirtiest areas (lower panels and wheels) are rinsed last.
  • Avoid high-pressure streams too close to the surface to prevent damage.

3. Wash One Section at a Time

  • Dip the microfiber wash mitt into the soapy water bucket (Bucket #1).
  • Wash a small section of the car using straight-line motions (not circular, to avoid swirl marks).
  • After washing a section, rinse the mitt in Bucket #2 to remove dirt and contaminants.
  • Rub the mitt against the grit guard to dislodge trapped particles.
  • Re-dip the clean mitt into the soapy bucket and continue washing the next section.

4. Wash Wheels Separately

  • Use a separate wash mitt or wheel brush to clean the wheels.
  • Rinse the wheels thoroughly before washing to remove brake dust and grime.
  • Avoid using the same wash mitt for the body and wheels to prevent contamination.

5. Final Rinse & Drying

  • Rinse the entire car thoroughly with clean water to remove all soap residue.
  • Use microfiber drying towels or a touchless air blower to dry the surface.
  • Avoid using chamois or rough towels, as they can leave micro-scratches.

Key Tips for an Effective Two-Bucket Wash

To ensure maximum effectiveness and prevent damage to your ceramic-coated car, follow these additional best practices:

  • Always use grit guards to trap dirt at the bottom of the buckets.
  • Never reuse dirty water from the rinse bucket in the wash bucket.
  • Wash in the shade to prevent soap from drying too quickly and leaving streaks.
  • Work from top to bottom, as lower panels accumulate more dirt.
  • Use multiple wash mitts, especially for highly contaminated areas like the wheels and lower sections.

Maintaining the Hydrophobic Properties

To ensure maximum effectiveness and prevent damage to your ceramic-coated car, follow these additional best practices:

  • Use a ceramic-safe quick detailer or booster spray after washing to enhance the coating’s water-repelling effects.
  • Avoid automatic car washes, especially those with brushes, as they can degrade the coating.
  • Wash the car every 1-2 weeks to prevent dirt buildup and maintain the hydrophobic layer.
  • Reapply ceramic coating boosters as recommended by professionals.
