For fabric seats or carpeted areas, dilute Simple Green accordingly and use a soft brush to lift dirt and stains. Ensure proper ventilation during and after cleaning to expedite drying and maintain a fresh interior ambiance.

9. Mindful Drying Techniques

Invest in a quality microfiber drying towel to minimize the risk of water spots. Pat the surface dry instead of rubbing, reducing friction and preserving the integrity of your car’s paint.

10. Regular Maintenance

Consistency is key. Establish a regular car cleaning routine using Simple Green to prevent the buildup of dirt, grime, and contaminants. This not only maintains your car’s appearance but also contributes to its overall longevity.
