Nerta Special 4000

Nerta Special 4000 is a concentrated alkaline maintenance cleaner (pH ~10.8) designed for everyday vehicle washing on cars, vans and commercial fleets — it lifts dirt, road film and light contamination with a strong foaming effect and predictable, repeatable cleaning power for routine wash schedules.

The lightly alkaline formulation strikes a balance between cutting power and ease of use, making it a reliable workhorse for valeting bays, fleet wash teams and mobile detailers who need consistency across many vehicles.

This is a concentrated formula and must be diluted before use.

FAQs

How does Special 4000 differ from a heavier-duty TFR like Foam Cleaner Yellow?
Special 4000 is positioned as the everyday maintenance cleaner — strong enough for routine grime but designed to be used regularly. Foam Cleaner Yellow is for occasional deep-cleaning of heavily soiled fleet vehicles.

Can it be used on a daily wash schedule for high-mileage taxi or rental fleets?
Yes — the formula is engineered for daily fleet use. For ceramic-coated cars in the same fleet, switch to a pH-neutral wash to preserve coating life.

Will it work effectively in cold British winter washing conditions?
Yes, but allow slightly longer dwell time when ambient temperatures drop below 5°C and pre-rinse with warm water if available to keep cleaning power consistent.

Is it safe for use on signage and vinyl wraps?
For laminated standard vinyl wraps it is safe at correct dilution and short dwell. For matte and textured wraps, test a small area first or switch to a pH-neutral wash to avoid dulling.
