Bilt Hamber Auto-Foam is a powerful, water-based snow foam pre-wash designed to soak and saturate dirty vehicle surfaces before contact washing. Its non-caustic formula provides strong cleaning performance against road grime and heavy contamination without dulling high-gloss finishes. Unlike snow foams developed primarily to create thick, lingering foam, Auto-Foam uses rapid-wetting technology to maximise surface contact and cleaning performance.

Key Benefits

• Effective Pre-Wash Cleaning: Loosens and removes road grime, traffic film, and heavy surface contamination before contact washing.
• Maximum Wetting Technology: Rapidly spreads across the surface to soak and saturate dirt rather than relying on unnecessarily thick foam.
• Non-Caustic Formula: Provides powerful cleaning performance without using caustic soda.
• Safe for High-Gloss Finishes: Will not dull automotive paintwork when used according to the manufacturer’s directions.
• Reduces Contact Washing Risk: Removes a substantial amount of contamination before your wash mitt touches the paint, helping minimise wash-induced marring.
• Easy to Rinse: The highly wetting formula rinses cleanly and carries loosened contamination away from the surface.
• Foam Lance Compatible: Suitable for use with pressure washer foam lances.
• Economical Concentrate: Applied at a typical 4% Panel Impact Ratio for dependable and repeatable cleaning performance.

Why Auto-Foam Is Different

Auto-Foam is designed around cleaning performance rather than producing the thickest possible foam. Its rapid-wetting formula spreads across the surface, penetrates contamination, and helps loosen grime during the dwell period.

The foam may appear wetter and collapse faster than heavily thickened snow foams. This is intentional and allows the cleaning solution to maintain close contact with the paintwork while it works.

Recommended Dilution

Apply Bilt Hamber Auto-Foam at a typical 4% Panel Impact Ratio (PIR). The amount added to your foam cannon will vary depending on the pressure washer, foam cannon, water flow, and equipment settings.

To calculate your required mixture:

1. Fill the foam cannon with a measured amount of water.
2. Spray the full contents into a bucket.
3. Measure the total amount of water collected.
4. Calculate 4% of the collected volume to determine how much Auto-Foam should reach the vehicle.
5. Adjust the concentration in your foam cannon as required.

How to Use

1. Prepare the Mixture: Dilute Auto-Foam to achieve a typical 4% Panel Impact Ratio.
2. Apply Evenly: Cover the vehicle thoroughly using a pressure washer foam lance.
3. Allow to Dwell: Leave the product on the surface for approximately five minutes while ensuring it does not dry.
4. Rinse Thoroughly: Pressure rinse the vehicle to remove the loosened grime and remaining product.
5. Contact Wash if Required: Follow with your preferred automotive shampoo and safe wash method.

Perfect For

• Removing road grime before contact washing
• Regular vehicle maintenance
• Heavily contaminated vehicles
• Reducing wash-induced swirls and marring
• Professional detailing workshops
• Enthusiast vehicle care
• Use with pressure washer foam lances

Important Information

Do not allow Auto-Foam to dry on the surface. Avoid applying the product to hot panels or in direct sunlight. Always calculate dilution using Panel Impact Ratio rather than relying only on the amount placed inside the foam cannon.

PRO TIP: Do not judge Auto-Foam by the thickness of the foam. Its wetter, fast-acting consistency is designed to maximise surface contact and cleaning performance. Correctly calculating a 4% Panel Impact Ratio will produce far better results than simply filling the foam cannon with an estimated amount.
