It’s highly effective at removing light dirt and grime, making it an excellent choice for regular maintenance washes. The foam also rinses off easily, leaving the vehicle clean without any residue.

Dilution Ratio: The Panel Impact Ratio (PIR) for Auto-Foam is 4%, but the actual dilution varies depending on the foam lance and pressure washer used, typically ranging between 300-450ml per litre of water.

2. Bilt-Hamber Touch-Less

  • Rating: 4.5 stars

Bilt-Hamber Touch-Less is another excellent snow foam shampoo from Bilt-Hamber, designed for users who want a quick and easy way to clean their vehicles. It can be rinsed without pressured water.

Performance: Despite being touchless, this product provides a powerful cleaning effect. It’s particularly effective at removing road grime and traffic film. The foam is not as thick as traditional snow foams, but it still clings to the surface long enough to break down dirt and contaminants. It’s ideal for lightly soiled vehicles or for users who want a quicker wash.

Dilution Ratio: The recommended dilution ratio for Bilt Hamber Touch-Less varies depending on the level of contamination. For maintenance washes, a 0.5% Panel Impact Ratio (PIR) is typically used, while for heavily soiled vehicles, a 2% PIR is recommended.

Best Snow Foam FAQs

Q: When should customers use pH-neutral snow foams?
A: pH-neutral snow foams are ideal for vehicles with protective coatings, such as vinyl wraps or paint protection film (PPF), as they clean without stripping away any protective layers or damaging the wrap.

Q: Can alkaline snow foam damage paintwork?
A: No, alkaline snow foams are generally safe for vehicle paintwork. They are effective at removing dirt and grime without causing damage. However, it's important to use them as directed and to rinse thoroughly to prevent any potential issues.

Q: Are alkaline snow foams better than pH-neutral ones?
A: Generally, alkaline snow foams tend to have stronger cleaning power, making them more effective at removing stubborn dirt and grime. However, pH-neutral snow foams are gentler on the vehicle's surface and are safer for vehicles with protective coatings. The choice between the two depends on the specific cleaning needs and the type of vehicle.

Q: How do I properly use snow foam on a wrapped vehicle?
A: When washing a wrapped vehicle, it's recommended to use a pH-neutral snow foam to avoid damaging the wrap. Apply the snow foam using a foam lance, allow it to dwell for a few minutes, then rinse thoroughly. Always use a two-bucket wash method with grit guards to minimize the risk of scratching.

Q: Can I use snow foam on vehicles with paint protection film (PPF)?
A: Yes, snow foam can be used on vehicles with PPF. It's advisable to use a pH-neutral snow foam to ensure the protection layer remains intact. Always follow the manufacturer's guidelines for both the snow foam and the PPF to maintain the vehicle's appearance and protection.
