Nerta Carnet Jumbo is a lightly alkaline professional vehicle wash and maintenance cleaner (pH ~10.6) engineered for fleet wash teams that need a fast, efficient daily cleaner for cars, vans and commercial vehicles — it lifts road grime, dust and dirt with predictable, repeatable results. Designed as a workhorse fleet shampoo, Carnet Jumbo handles high-volume daily wash schedules without the heavy-duty alkalinity of a full TFR — striking the balance between cleaning power and routine usability for taxi fleets, delivery vans, mobile valeting and trade wash bays. This is a concentrated formula and must be diluted before use. Why fleet operators choose Carnet Jumbo Reliable daily fleet cleaner for high-volume vehicle wash teams Effective on road grime, dust and traffic film Lightly alkaline (pH ~10.6) — strong but routine-friendly Concentrated formula for low cost-per-vehicle Compatible with sponge, brush, foam lance and wash arches Suitable for cars, vans, taxis, motorhomes and commercial fleets How to use Carnet Jumbo Pre-rinse the vehicle with clean water. Dilute Carnet Jumbo as required for your equipment and dirt level. Apply via sponge, brush or wash system from the bottom up. Agitate stubborn areas if needed (do not let it dry on the surface). Rinse thoroughly with clean water before drying or moving to next vehicle. Specifications Type: lightly alkaline professional fleet wash cleaner Sizes: 5L, 20L, 200L, 1000L (see variants) Dilution: 1:20 to 1:100 — follow label per application pH: ~10.6 (lightly alkaline) Use on: cars, vans, taxis, motorhomes, commercial fleets FAQs How does Carnet Jumbo differ from heavier-duty TFRs in the Nerta range?It sits in the middle of the range — stronger than a pH-neutral shampoo but lighter than a heavy-duty TFR like Foam Cleaner Yellow. Pick Carnet Jumbo when you need predictable daily cleaning rather than occasional heavy-duty cuts. Is it suitable for taxi fleets that wash multiple times a week?Yes — the formulation is engineered for daily and twice-daily wash cycles. For ceramic-coated taxis, switch to a pH-neutral shampoo to extend coating life. Will it produce noticeable foam in a foam-lance, or is it more of a sprayer/wash-arch chemical?It is more of a wash-system and brush chemical than a thick foam-lance product. Use a dedicated snow foam if your routine includes a foam-lance pre-wash stage. Can it be used for cleaning workshop floors and concrete forecourts as well as vehicles?It can handle light forecourt cleaning at higher concentration but for heavy oil and tyre marks on concrete you will get faster results from a dedicated floor degreaser.
