Surfactants and Sticky Floors

Those environmentally friendly surfactant type cleaners can be less than friendly to your floors.

Surfactants leave residue on surfaces. How much, depends on how much was in the cleaner, to begin with — more does not equal better here. If you’re not using dilution control for your cleaning products, that’s probably why your bus floors are sticky.  There are some cleaning chemistries that leave more residue than others, for example, a quaternary disinfectant used for bio-hazards has incredibly sticky chemistry.  These floors can turn black quickly!

Residue build-up can cause other problems. That sticky film on surfaces is the perfect place for biofilm to grow. According to the CDC, bio-film happens when bacteria sticks together on a surface.

Residue also causes odors to linger. If what’s causing the odor is embedded deep in a sticky film, you better believe it’s going to keep coming back.

Material Failure in Bus Step Treads

Durability is critical for student and passenger safety.
Failure of a school bus step tread.

Are you seeing this in the step wells of school buses and commercial shuttle buses?  Why is it happening?

In the field of material science this is an example of the brittle failure of a material.  These are molded rubber parts that have been attached to a metal backing and installed as the wear surface on a step in a school bus.

Step treads should never fail in this way.  Material placed in demanding service like this should be compounded to have physical properties that make this type of failure impossible.

What can you do to have greater assurance that step treads last the life of the bus?

An extended warranty against brittle failure would be one way.

We’d like to know what you think of this idea, and would an extended warranty against brittle failure be a factor in the step treads you specify for new buses.  And, what do you think the length of the extended warranty against brittle failure should be?

Please share your thoughts below and send your brittle failure photos to
