To wash and dry your car without physically touching it, you can utilize a combination of waterless car wash products, foam applications, and pressure washing techniques.

Here’s a step-by-step guide based on the latest methods:

1. Preparation

• Choose the Right Location: Find a shaded area to prevent the cleaning solution from drying too quickly, which can leave spots on the paint.
• Gather Supplies: You will need a waterless car wash solution, foam applicator, pressure washer, and microfiber towels.

2. Waterless Car Wash

• Select a Quality Product: Use a reputable waterless car wash product. Some popular options include Meguiar's Ultimate Waterless Wash & Wax and Chemical Guys Hyper Wash.
• Application: Spray the waterless wash generously on a panel of the car. Start from the top and work your way down. This method is effective for cars that are slightly to moderately dirty.

3. Foam Application

• Use a Foam Cannon: If you have a pressure washer, attach a foam cannon filled with a foam wash solution. This will create a thick layer of foam that clings to the surface, loosening dirt and grime without the need for scrubbing.
• Let it Sit: Allow the foam to dwell for a few minutes to break down the dirt.

4. Pressure Washing

• Rinse Off: Use a pressure washer to rinse off the foam. This method allows you to clean the car without touching it, effectively removing dirt and debris.
• Adjust Pressure: Ensure the pressure is set appropriately to avoid damaging the paint.

5. Drying

• Use a Blower: After rinsing, use a car dryer or blower to remove excess water. This method prevents water spots and eliminates the need for towels that could scratch the surface.
• Final Touch: If desired, you can apply a quick detailer spray to enhance shine and protection.

Additional Tips

• Regular Maintenance: Regularly using a waterless wash can help maintain your car's appearance and reduce the need for more intensive cleaning.
• Check Product Compatibility: Ensure that the products you use are compatible with your car's paint type.
