Heavily alkaline, phosphate-free pre-wash concentrate aimed at express carwash and tunnel operations where dwell time is short. A loaded blend of complexing agents, surfactants, and additives breaks down insects, droppings, and engine and rim soiling fast, and the formula plays well with biological service-water treatment plants.

체류 시간이 짧은 익스프레스 세차장과 터널 라인을 위해 만든 인산염 없는 강알칼리 프리워시 농축액입니다. 킬레이트제와 계면활성제, 보조 첨가제를 풍부하게 담아 곤충 잔해, 새 배설물, 엔진과 휠의 오염을 빠르게 풀어 주며 생물학적 처리수 시스템과도 잘 맞습니다.

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.
