Strong-alkaline pre-cleaner and wheel cleaner tuned for the short dwell of express high-pressure carwash lines such as Holz systems. Doubles as a precleaner ahead of an insect step and as a rim cleaner, with high water-hardness tolerance so feed lines stay free of mineral deposits.

Holz와 같은 익스프레스 고압 라인의 짧은 작용 시간에 맞춰 만든 강알칼리성 프리·휠 클리너입니다. 인섹트 공정에 앞서는 사전 처리제로도, 휠 클리너로도 활용할 수 있고 경수 환경에서도 라인에 침착물이 거의 남지 않을 만큼 경도 내성이 좋습니다.
