Highly alkaline, low-foaming pre-wash concentrate with phosphate, formulated to break tough adhesions like insect bodies, bird excrement, environmental film and rim soil within very short contact times. Built around chelants, surfactants, alkalis and special boosters, it suits express wash tunnels with closed pre-wash circuits and alkaline wash-bay cleaning. Quick-separating per ÖNORM 5106 and meets VDA class B.
킬레이트제, 계면활성제, 알칼리, 특수 첨가제를 균형 있게 배합한 강알칼리·저발포 프리워시 농축액으로 인산염을 함유합니다. 짧은 반응 시간 안에서 벌레 자국, 새 분비물, 환경 오염, 휠 때 등 강한 부착 오염을 분해하기 때문에 폐쇄 회로 익스프레스 세차장과 알칼리 워시베이 청소에 잘 맞습니다. ÖNORM 5106 빠른 분리 기준에 부합하고 VDA 클래스 B 인증을 받았습니다.

How it works
- Alkaline cleaning — Alkaline chemistry that breaks down grease; can stain aluminium and matte finishes.
- Chelates minerals — Binds metal ions in water to reduce spotting and loss of cleaning power.
- Cleaning surfactant — Lifts soil off the surface and disperses it in water.
- nonionic surfactants — Ionic types of the surfactants used in this product.
