Exterior washing using pH neutral soaps and foam cannons can provide a range of benefits for your vehicle, including:

1. Gentle cleaning: pH neutral soaps are specifically formulated to clean your vehicle's exterior without damaging the paint or other surfaces. They are gentle on your car's finish, while still effectively removing dirt, grime, and other contaminants.
2. Preventing scratches and swirl marks: Foam cannons are designed to create a thick, rich lather that clings to the surface of your vehicle, providing a lubricated layer between the soap and the paint. This helps to prevent scratches and swirl marks that can occur during the washing process.
3. Saving time and water: Using a foam cannon can help you save time and water during the washing process. The thick foam clings to the surface of your vehicle, providing an extended dwell time that helps to loosen and lift dirt and grime, so you don't have to scrub as hard.
4. Eco-friendly: pH neutral soaps and foam cannons are environmentally friendly, as they don't contain harsh chemicals that can harm the environment or damage your car's finish.
5. Improved shine and gloss: Regular washing with pH neutral soaps and foam cannons can help to improve the shine and gloss of your car's finish. The gentle cleaning action removes dirt and contaminants that can dull the finish, leaving your car looking its best.

In summary, using pH neutral soaps and foam cannons for exterior washing can help to keep your vehicle looking its best while minimizing the risk of damage to the paint or other surfaces. It's a safe, effective, and environmentally friendly way to clean your car.
