Vorreiniger B Precleaner – Alkaline High-Foam Prewash

Vorreiniger B Precleaner is a highly concentrated, phosphate-free alkaline prewash for professional car and truck cleaning. It creates strong foam and removes heavy dirt quickly during the prewash stage.

Vehicles collect insects, bird droppings, road film and brake dust every day. Therefore, an effective prewash is essential. Vorreiniger B Precleaner combines powerful surfactants with high-quality complexing agents. As a result, it loosens stubborn dirt before the main wash cycle begins.

You can use Vorreiniger B Precleaner in:

• Automatic gantry carwashes

Special corrosion inhibitors protect sensitive parts such as anodised aluminium. Consequently, the product delivers strong cleaning while maintaining material safety.
