Nerta Tropical Blast is a high-foaming lightly alkaline pre-wash with an intense tropical fruit fragrance — it produces a thick clinging foam that breaks down traffic film, dirt and light grease before the contact wash, leaving a fresh tropical scent in your wash bay. The lightly alkaline pH (~11) gives stronger cleaning power than pH-neutral pre-wash foams while remaining manageable for regular use on cars, vans and commercial vehicles in valeting bays and mobile detailing setups. This is a concentrated alkaline pre-wash and must be diluted before use. Why valeters love Tropical Blast Intense tropical fruit fragrance — transforms the wash-bay atmosphere Thick clinging foam with extended dwell time Lightly alkaline (pH ~11) for serious cleaning power Effective on traffic film, road dust, light grease and salt Compatible with foam lance, foam arch and pressure washer Concentrated for low cost-per-vehicle in busy wash bays How to use Tropical Blast Pre-rinse the vehicle to clear loose dirt and dust. Dilute Tropical Blast as directed for your equipment. Apply via foam lance or sprayer, working from the bottom up. Allow 3–5 minutes dwell on the surface — do not let the foam dry. Rinse off thoroughly with clean water before contact washing. Specifications Type: high-foaming lightly alkaline pre-wash foam Sizes: 5L, 20L, 200L, 1000L (see variants) Dilution: 1:10 to 1:50 in foam lance pH: ~11 (alkaline) Scent: tropical fruit Foam density: thick, clinging Use on: cars, vans, motorhomes, light commercial FAQs How does the tropical fragrance compare to typical industrial pre-wash chemicals?Tropical Blast smells noticeably more like a tropical cocktail than chemistry — customers in mobile valeting often comment on the wash-bay scent during the job. Is it strong enough for HGV grime, or only car-grade dirt?It handles light HGV traffic film at the strongest dilution, but for very heavily soiled HGV trailers step up to Sky WE 64 or Mega Foam Cleaner for maximum cutting power. Will the alkaline pH dull a freshly waxed or sealed car?Repeated use will gradually thin out wax and sealant. For coated or freshly waxed cars, switch to a pH-neutral pre-wash like Active Foam Perfumed. Is the colour and fragrance dye permanent if it splashes onto clothes?The dye and fragrance rinse cleanly with water and a quick wash and do not stain typical work-wear at usage dilution.
