Bilt Hamber Auto Foam 5L - Pre-Wash Snow Foam Shampoo

Auto-Foam is the result of extensive in-house research and development. Auto-Foam will reduce even further the possibility of damage to paintwork by presenting you with beautifully clear FOD free paint, ready for subsequent detailing.

Auto-Foam is a new generation premium quality, foaming water-based pre-wash treatment, designed to soak and saturate soiled vehicle paintwork prior to the application of vehicle shampoo and paint food. Auto-Foam is gentle too, and is for use with all pressure washer foam lances. Applied at a typical PIR (Panel Impact Ratio) of 4%, Auto-Foam will panel-dwell for typically five minutes. Auto-Foam is formulated specifically to offer maximum wetting and it rinses easily too. It is not designed as a superficial high foam product, but as a functional material.

Auto-Foam is made with biodegradable compounds, is extraordinarily tough on soil and grime, yet harmless to paint. The non-caustic formulation ensures that even regular use will not attack paint binders. Our hard-working surfactants will attack and penetrate the hardest of road dirt and grime, without the need for manual intervention.

During the panel-dwell period, Auto-Foam’s bubbles will systematically burst and move, encouraging our soaking and cleansing agents to start working. The effects of road grime are neutralised by them, by being bonded within our blend of surfactants, and then lifted from painted surfaces and physically removed, minimising harm caused by swirling and marking during subsequent detailing.

When Auto-Foam’s work has been done, it may be washed off in a conventional manner, leaving a well presented automotive surface ready for further treatments.

For excessively soiled surfaces, simply increase PIR and/or number of applications.

How To Use
Use on a cool surface.
Dilute as required to obtain a PIR (panel impact ratio) of between 1:100 and 5:100.

FAQs

Q: Is Bilt Hamber Auto-Foam pH Neutral?

A: No, Bilt Hamber Auto-Foam is not pH neutral. It is an alkaline-based pre-wash with a pH range of 13. Being alkaline based gives it strong cleaning power without damaging wax, sealants and paints as its non-caustic. 

Q: Is Bilt Hamber Auto Foam a pre-wash?

A: Yes, Auto Foam is an excellent pre-wash designed to remove as much contaminants and dirt off your car's paintwork before the contact and shampoo stage. 

Q: What is the mixing or dilution ratio for Bilt Hamber Auto Foam?

A: Bilt Hamber recommend a panel impact ratio (PIR). This is to do with the amount of chemical that makes contact with your car when coming out a sprayer or lance. This varies depending on the pressure washer and foam cannon. We can recommend that you calculate this for best results. This can practically vary from 100ml to 400ml of product per litre.

Q: What is the recommended concentration for a heavily soiled vehicle?

A: Depending on the level of dirt on your vehicle you can increase/decrease the amount of product use to be more economical. You should use the PIR, the volumes are good gauges. For heavily soiled vehicles - 4% PIR (approx. 400ml/litre), medium 3% (300ml/litre), light 2% (200ml/litre). You should use the PIR, the volumes are rough gauges.

Q: What is the difference between Bilt Hamber Touchless and Autofoam?

A: Touch-Less is great for regular cleaning, it has a lower pH and is more concentrated than Autofoam. It also can be easily rinsed off. Auto-Foam is better at tackling heavy dirt and grime, being thicker and higher in alkaline. It depends on your needs. For an in depth comparison, please read our blog.
