Nerta High Foam Cleaner is an alkaline pre-wash foam (pH ~11) with a citrus fragrance designed to deliver balanced foaming performance for regular pre-wash use on cars, vans and commercial vehicles — it loosens dirt and grime before contact washing without the most aggressive chemistry of a heavy-duty TFR. Targeted at hand car wash bays, mobile valeting and routine fleet washing, High Foam Cleaner produces a thick clinging foam that gives good visual coverage and dwell time so dirt releases ahead of the rinse stage. This is a concentrated alkaline pre-wash and must be diluted before use. Why operators choose High Foam Cleaner Balanced alkaline foam pre-wash for regular wash bay use Thick clinging foam with strong visual coverage Citrus fragrance for a more pleasant working environment Compatible with foam lance, foam system and sprayer Effective on traffic film and routine road grime Suitable for cars, vans, motorhomes and commercial vehicles How to use High Foam Cleaner Pre-rinse the vehicle to clear loose dirt and dust. Dilute High Foam Cleaner as required for your equipment. Apply via foam lance or sprayer, working bottom-up for full coverage. Allow 3–5 minutes dwell on the surface (do not let it dry). Rinse off thoroughly before contact washing. Specifications Type: alkaline pre-wash foam cleaner Sizes: 5L, 20L, 200L, 1000L (see variants) Dilution: 1:10 to 1:50 in foam lance pH: ~11 (alkaline) Scent: citrus Foam density: thick Use on: cars, vans, motorhomes, commercial vehicles FAQs How does High Foam Cleaner sit alongside Foam Cleaner Yellow and Traffic Foam Cleaner?High Foam Cleaner is the everyday choice — less aggressive than Yellow and Traffic Foam, ideal for routine pre-wash. Step up to Yellow or Traffic Foam only when handling exceptionally heavy fleet grime. Is the citrus fragrance noticeable on customer cars after rinsing?The citrus scent fades within an hour of rinsing, so customers do not drive away with a strong residual smell on bodywork. Can I run a thinner dilution for routine fleet vehicles to reduce cost?Yes — for lightly soiled fleet cars, dilute towards the weaker end of the range. Save the stronger dilution for vehicles returning from heavy motorway use. Will it work with cold rinse water in winter, or should I use warm water?Cold water will work but allow slightly longer dwell time below 5°C. If warm water is available, cleaning power and foam consistency improve noticeably. UK stock and fast dispatch from SnowFoam UK on every order.
