GrimeCrusher Hi pH Presoak

Our Strongest Presoak Ever.

The dirt on a vehicle is rarely just loose dust. Road film contains oily residue mixed with fine dirt and other material that sticks to the body of a car. AutoLux GrimeCrusher Hi pH is an alkaline presoak developed to break up and wash away that buildup in touch-free washes.

We created GrimeCrusher for operators who want the strongest cleaning in touch-free washes. Our goal was to develop our strongest touch-free presoaks yet while keeping the price competitive. GrimeCrusher Hi pH gives operators a high-pH option for washes dealing with nasty film and organic deposits.

Built to lift and disperse soil

GrimeCrusher Hi pH combines multiple sources of alkalinity with a specialized detergent. The alkaline ingredients support cleaning and help the formula tolerate hard water.

The detergent has more than one job. It helps break up and disperse soils, and it supports the formula’s stability at high pH. By keeping loosened dirt dispersed in the wash solution, the presoak helps prepare it to be rinsed away from the vehicle.

The formula produces dense foam designed to cling to the vehicle while the chemistry works.

A flexible fit for your wash

GrimeCrusher Hi pH can be used on its own or paired with GrimeCrusher Lo pH in a two-step wash. That gives operators a choice based on their equipment, water and the soil conditions at their site.
