Bilt Hamber Auto Foam – Pre-wash snow foam shampoo

It is pointless to use expensive waxes and sealants while striving to achieve a perfect finish if you don’t get the basics right from the beginning. Most swirls and paint imperfections have to be addressed later on in the process because of poor detailing preparation and the effects of Foreign Object Damage (FOD) on paint (such as ‘own goal’ damage from grit and grime) having to be removed. However careful we all might strive to be, sometimes we make mistakes and damage happens. So it makes sense to be as methodical and as careful as we can be, from the very first stages of the cleaning process, not just at the end.

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

Bilt Hamber Auto Foam is a premium quality, foaming water-based pre-wash, designed to soak and saturate soiled vehicle paintwork prior to the application of vehicle shampoo, such as auto-wash. Bilt Hamber auto-foam is gentle too and can be applied with a foam lance bottle, or with a pump sprayer. Applied at a typical PIR (Panel Impact Ratio) of 4%, auto foam will dwell on the panel for typically 5 minutes. Bilt Hamber auto-foam is formulated specifically to offer maximum wetting, it rinses easily too. It is not designed as a superficial high foam product but as a functional snow foam.

Bilt Hamber AutoFoam is made with biodegradable compounds, is extraordinarily tough on soil and grime, yet harmless to paint, its 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, Bilt Hamber 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 the harm caused by swirling and marking during subsequent detailing.

When its work has been done, Bilt Hamber auto-foam may be washed off in a conventional manner, leaving a well presented automotive surface, perfectly ready for further treatments.

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

    Auto-Foam is quite simply the best foam pre wash treatment you’ll find on the market.
    It’s designed not to foam as others do allowing 100% of the product to be active on the car, cleaning away dirt, grime and road film.
    Dilution rates are a lot higher than other brands but you use so little of the solution that the product will last a very long time making 5L of it very economical

    best foam iv used to date use 150ml in the lance good cleaning power recently used it on our toyota yaris hasnt been washed is 6 months used 200ml foam and 800ml water very strong cleaning power litraly touchless wash very impressive even the sills had little to no dirt after using it

    The stuff needs no introduction. I’ve found adding 50-100ml of any other cheap “showfoam” will make this cling a bit longer too. Which I’ve found useful

  4. MARK KERR (verified owner)

    As good as its reputation, unrivalled cleaning power and ridiculously easy to rinse off compared with other pre-wash products I’ve used.

    I would recommend spending the time to calculate the correct ratio for your lance – see videos on YouTube ??

    Just purchased another 2 x 5L bottles,due to this product being so phenomenally impressive! Since my previous review (20 March), having gained more experience of using Auto Foam, I would recommend just using 100ml in a 1L lance bottle – certainly no more required if you wash weekly.

    Unlike most snowfoams, I wouldn’t allow this to dwell for more than 5 minutes, particularly in the warmer spring/summer months as ug can dry out quickly. It will have done its job by this stage so I would recommend pressure washing it off after no more than 5 minutes and following it up by washing the vehicle with Bilt Hamber Auto Wash.

    If there is excess road grime/bugs on the vehicle, I would also suggest either spraying the lower half first with Bilt Hamber Surfex HD mixed at 1:9 with water or simply adding 50-100ml of Surfex HD into you snowfoam mixture.


    Great cleaning power although not as thick as others so doesn’t cling as well! Great value for money

    Not very foamy but a thick snowfoam is for show anyway. Autofoam clings well and has great cleaning ability. Highly recoomended.
