Its non-caustic formula safely penetrates and lifts tough grime while protecting paintwork and existing waxes. Optimized with a 4% Panel Impact Ratio, it delivers effective soak and dwell time for superior dirt removal using any pressure washer foam lance. Perfect for millennial managers who demand a flawless finish and eco-conscious care. ## Description Product Description Pre-wash snow foam shampoo. There is absolutely no point in using expensive waxes and sealants striving to achieve a perfect finish if you don’t get the basics right at the outset. 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. 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. Ingredients Non-caustic. Effective touchless cleaning action. Biodegradable.

Bilt Hamber uses PIR (panel impact ratio) to calculate the correct mix ratio of product/water so you are always going to get good results as the mix ratio is calculated to the performance (flow rate) of your pressure washer. It is very easy to calculate, instructions are on the container or can be found online. Overall the results are very good; it is not a high foaming product as some pre washes are, but thick foam does not mean good performance. Leave to dwell for 5 minutes then rinse, all light dirt will be gone and any heavy soiling will have been softened, making it easier to remove with the pressure washer or by hand. A useful thing to do if you have heavily soiled wheels & tires with plenty of brake dust build up is to spray each wheel with your wheel cleaner before applying this product, then spray this over the top covering both wheel and tire as it will increase the dwell time of your wheel cleaner making wheel cleaning a lot easier. I’ve used about 20L of this so far on a number of vehicles and it has always performed well. Half a litre is usually enough to cover a medium sized car, so 5L does go a long way. It’s also kind to any pre applied waxes or treatment on the bodywork and will not strip or thin these out. Review: Strips the UK winter and grime away brilliantly - The difference from the Karcher supplied foam is night and day. Goes on brilliantly via the Karcher wand bottle - only used 100ml for all the car and almost went round it twice to use up. Strips the UK winter grime and salts easily - brilliant product. ## Features - Causes serious eye damage. - 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 - auto-foam 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.

Good quality ceramic coatings are more that capable of handling high strength snow foam like this. **Q: Bought this well reviewed product for use on my car, However, not yet tried it. Would this be safe to use on a motorcycle?** A: Safe enough on any vehicle but watch the pressure washer spray "hardness" as not always the right method for motorbikes. Pressure washers can be a little brutal on bikes. Also remember as you force water/foam "in" you have also to get it out again. Buy a pet dryer as means of extracting all the excess water from nooks and crannies. **Q: Can I use this a boat gel coat?** A: I don’t think so. It´s a pre wash solution and not coating. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A very good contactless pre wash *by D***N on 9 June 2022* A very good and safe way to contactless pre wash your vehicle - definitely one of the better pre washes on the market.

Goes on brilliantly via the Karcher wand bottle - only used 100ml for all the car and almost went round it twice to use up. Strips the UK winter grime and salts easily - brilliant product. ### ⭐⭐⭐⭐ Bilt Hamber Auto Foam (5 Litre) *by K***E on 2 February 2020* Bought again as my BH snowfoam had depleted. Really good quality car snow foam which I apply via Kranzle Snow Bottle attached to a Kranzle cold pressure washer. This BH product is really great for cleaning your car BUT you need to get the ratio of snowfoam to water correct. Takes a bit of trial and error. Apply using snow foam lance at correct spray setting and leave to dwell on vehicle for 10 to 30 mins then simply spray off with pressure washer attachment. Have tried various snowfoam products over the years, Auto Finesse, AutoBrite, to name but a few but have always found BH products to be the best. Again only gripe is that the prices of BH always seem to creep up as is always the case with a superior product. This review is my own personal experience of using this Bilt Hamber Snow Foam and oothers will disagree.
