Nerta Blue Diamond is a powerful alkaline pre-wash and traffic film remover (pH ~12) engineered to cut through heavy traffic film, road grime and motorway-grade contamination on cars, vans, HGVs and commercial fleets. Distinctive blue colour and aggressive alkaline chemistry make Blue Diamond a workhorse choice for fleet wash teams handling harsh-condition vehicles — ideal for sprayer or wash-system delivery as the heavy-duty pre-wash stage before contact washing. This is a concentrated alkaline TFR and may be corrosive to metals — read the safety data sheet before use.

Specifications Type: heavy-duty alkaline pre-wash and TFR (corrosive to metals) Sizes: 5L, 20L, 200L, 1000L (see variants) Dilution: 1:10 to 1:50 — follow label per dirt level pH: ~12 (strongly alkaline) Use on: HGV trailers, vans, commercial vehicles, fleet FAQs How is Blue Diamond different from TC 2000 — they are similar in pH?Both are pH ~12 alkaline TFRs. Blue Diamond carries the corrosive-to-metals warning and is positioned for harshest conditions; TC 2000 is the workhorse industrial cleaner for routine HGV use. Is the blue dye permanent on a wash-bay floor or workshop overalls?The blue colour is water-soluble and rinses cleanly with water at usage dilution. It does not stain washed concrete or typical work-wear after a normal laundry cycle. Will it strip wax or sealant on a fleet vehicle?Yes — at pH 12 expect any wax or sealant to be stripped over time. Use Blue Diamond where heavy cleaning trumps long-term protection. Can it be safely run through a roll-over carwash arch?Yes when correctly metered for the equipment.
