Bilt-Hamber Autofoam is a premium water-based pre-wash formulated to soften and dissolve stubborn road grime without contact – before the main wash begins. The product is an active Snow Foam that works with advanced surfactants to penetrate and loosen dirt, sand, and road deposits without risking damage to the paintwork.

Autofoam from Bilt-Hamber is not designed to produce a thick, decorative foam blanket. The foam is intentionally formulated to break and run off – forcing the surfactants to continuously work against the dirt throughout the entire dwell time. The result is a more effective clean compared with products that prioritise visual foam depth over function.

The product is non-caustic and biodegradable, making it suitable for regular use without causing harm to the clear coat or its binders. See more Bilt-Hamber products for car care in our range.

What is Autofoam and why choose it?

Autofoam is Bilt-Hamber's answer to one of the most common problems in detailing: swirl marks (circular scratches in the paintwork) that occur when sand and coarse dirt are rubbed against the paint surface during the wash process. By using an active pre-wash such as Autofoam, the heaviest soiling is dissolved and rinsed away before a wash mitt or sponge is used, dramatically reducing the risk of paint damage.

The formula is developed for professional use and is equally suited to bodyshops and detailing studios as it is to enthusiasts who want to give their vehicle the correct treatment from the outset. The non-caustic formulation means the product can be used regularly without weakening the clear coat – an important criterion for anyone who has invested in a Coating or Sealant.

Where is this product suitable?

• Bodyshops and professional car care businesses
• Detailing studios focused on paint protection
• Hobby detailers and car enthusiasts
• Vehicles with paint-protecting Coating or Sealant that require gentle cleaning
• All vehicle types: passenger cars, vans, and motorcycles

Frequently Asked Questions (FAQ)

Does Bilt-Hamber Autofoam work as a pre-wash on vehicles with Ceramic Coating?

Yes, Bilt-Hamber Autofoam is formulated to be gentle on paint protection layers. The non-caustic formula does not break down Ceramic Coating or Sealant, making Autofoam a suitable choice for regular pre-washing on protected paint surfaces. Apply the foam to a cool, shaded surface and rinse off after approximately 5 minutes.

What volume and dilution apply to Bilt-Hamber Autofoam 5L?

Bilt-Hamber Autofoam is supplied in a 5-litre container. The recommended dilution when applying via a foam lance is typically 4% (PIR – Panel Impact Ratio), but can be adjusted between 1 and 5% depending on the level of soiling. A 5-litre container provides a large number of washes and is therefore cost-effective for professional use in detailing studios and bodyshops.

What sets Bilt-Hamber Autofoam apart from other Snow Foam products on the market?

Unlike many competing Snow Foam products, Bilt-Hamber Autofoam is not designed to produce a maximally thick foam layer. The foam is intentionally formulated to break and run off continuously, forcing the active surfactants to work against the dirt throughout the entire dwell time. The result is a more functional clean rather than a visually impressive but ineffective foam blanket. The formula is also biodegradable and non-caustic, which is important for regular use without paint wear. See also other pre-wash products in our range for comparison.
