Nerta Active Diamond Foam is a high-performance alkaline snow foam pre-wash (pH ~11.8) that produces a thick clinging foam to safely loosen dirt, traffic film and road grime before contact washing — reducing the risk of wash-induced swirl marks and micro-scratches on cars, vans and commercial vehicles. Designed for foam-lance and touchless wash use, Active Diamond Foam delivers extended dwell time and stronger cleaning power than pH-neutral pre-wash foams — ideal for detailing enthusiasts wanting a deeper pre-wash and professional fleet operators handling stubborn traffic film. This is a concentrated alkaline pre-wash and must be diluted before use. Why detailers choose Active Diamond Foam Thick clinging snow foam for maximum vertical dwell time Reduces wash-induced swirl marks by lifting dirt before contact Strong cleaning power on traffic film, road grime and dust Compatible with foam lance, sprayer and touchless wash systems Concentrated for cost-effective detailing and fleet use Suitable for cars, vans and commercial vehicles How to use Active Diamond Foam Pre-rinse the vehicle to clear loose dirt and dust. Dilute Active Diamond Foam at the rate suggested for your foam lance. Apply via foam lance or sprayer, working from the bottom up. Allow to dwell on the surface (do not let it dry). Rinse off thoroughly with clean water before contact washing. Specifications Type: high-performance alkaline pre-wash snow foam Sizes: 5L, 20L, 200L, 1000L (see variants) Dilution: 1:10 to 1:50 in foam lance pH: ~11.8 (alkaline) Foam density: thick, clinging Use on: cars, vans, motorhomes, commercial vehicles FAQs How does Active Diamond Foam differ from Nerta Snowfoam (the pH-neutral version)?Active Diamond Foam is mildly alkaline (pH ~11.8) for stronger cleaning. Nerta Snowfoam is pH-neutral and ceramic-coating safe. Choose Active Diamond Foam where cleaning is the priority and Snowfoam where coating safety is paramount. Will it strip wax or sealant on a freshly waxed car?With repeat use yes — the alkaline chemistry will gradually thin protection. For waxed and ceramic-coated cars, switch to Nerta Snowfoam. Is it suitable for touchless wash systems where there is no contact-wash stage?Yes — the formulation works as a touchless cleaner with extended dwell. Always rinse thoroughly with high-pressure water for best results. How does the foam dwell time compare with Hyperfoam or Foam Cleaner Yellow?Active Diamond Foam offers extended dwell with strong cleaning. Hyperfoam pushes maximum foam volume; Yellow is the heavier-duty fleet TFR. Pick the right tool for the job. UK stock and fast dispatch from SnowFoam UK on every order.
