Touchless Cleaning – What’s with Washing from the Bottom?

There’s a very good reason for power washing touchless soaps from the bottom upward.

Touchless cleaning is different to manual scrubbing—we don’t want gravity to interfere with the cleaning. Here’s why: Soap is applied through a high-pressure foamer (or via a downstream injector) and then high-pressure water is used to do the cleaning in place of scrubbing. The water is worked into the fresh soap, either using horizontal sweeps from the bottom to the top, or vertical sweeps moving backwards along a large vehicle.

The foam disrupts the static bond between the grime and the surface. It’s working harder than traditional soaps so that you don’t have to.

We use the high-pressure water to remove that grime while the foam is weakening it. Washing from the top, down just rinses everything onto the ground and removes the foam before we can make the most of that static disruption.

Once the whole surface has been cleaned, you can make use of gravity with a quick top-down final rinse.
