Cleaning Escalator Steps: Introduction to the Work

Most of the dirt that accumulates in the steps of the escalator comes from the dirt carried in from outside on footwear as well as fibers that fall from clothing due to rubbing.
The escalator is driven by a large chain under the steps.
The chain is oiled to ensure smooth movement and to prevent abrasion.

Over time, oil seeps out onto the surface of the steps. It mixes with fibers and dirt to form semi-solid stains.
To remove these oily stains, a detergent is required.

However, if a detergent is used, it is also necessary to rinse the steps, so that no detergent remains on the steps. This requires a lot of water and a lot of work.

If detergent remains on the steps, it will damage the painted finish, metal, and plastics.
However, if a harmless detergent could be used, rinsing would not be needed. The detergent could remain without any problem.

We developed our own detergent that is harmless even if it remains on the steps: ESW-FK-III. (It does not contain any synthetic surfactants or alkali auxiliary agents.)

Next, we wash the steps with a detergent that leaves no residue and then clean them with a vacuum cleaner.
No-residue detergent: ESW-ALP-50
Leaves no residue, so rinsing is unnecessary.
