Some machines are designed to
remove dirt using only the movement of the escalator itself,
without any additional agitation of the brushes. These
static-brush machines rely on expensive interchangeable “heads”
that fit only certain escalator widths. A facility with multiple
escalators of varying sizes must invest in as many heads for the
machine as they have escalators. Also, much time must be
invested whenever the machine is used, because the brushes do
not agitate on their own, to assist in cleaning.
Other machines remove dirt
even better and more efficiently with agitating cylindrical
brushes that work in addition to the powerful internal vacuum.
These machines are smaller and may be used on any size
escalator. Positioned at the non-moving base of the escalator
with the stairs moving upward and away, the machine remains
anchored while the cylindrical brushes move across the step,
loosening dirt and vacuuming it into a disposable bag.
Both machines require little
supervision, though it is advisable to have at least one person
in the area while the machine is operating in case there is a
problem.
How Often/Long Should You
Clean?
If the escalator treads are
heavily soiled and have not been cleaned for a long time, you
may need to run your cleaner for four hours or more to get them
clean, especially if you are using a static-brush machine. For
routine monthly or weekly cleaning, the agitating-brush machine
should get the job done in an hour to an hour and a half, while
the static-brush machine will probably take four to eight hours
or more.
Use Tynex brushes for deep
cleaning, and nylon brushes for routine maintenance. The Tynex
brushes should not be over-used as they are more abrasive than
sandpaper and may cause wear on your escalator over time.
Schedule your cleaning during off-hours when the building is
closed to visitors or during the slowest traffic time if the
building is open 24 hours. The average cleaning cycle is once or
twice a month, but if the escalator is in a high-traffic area,
it may need to be cleaned weekly. Remember, keeping up with the
regular maintenance schedule will keep your escalators looking
clean and inviting, and will prevent more serious problems from
developing.
What about Cleaning Chemicals?
Regular cleanings with dry
agitation and vacuuming will do a sufficient job of removing
soil from the escalator treads, even down in the hard-to reach
areas. Yet sometimes you may encounter a stain that requires a
little more treatment.
In such instances, a
low-moisture solution may be sprayed directly onto the soiled
area. Use a cleaning solution that lifts dirt and stains off the
treads and dries quickly and completely. Avoid any type of
cleaning product that will leave a film on the escalator. Any
cleaning solutions should be used sparingly to avoid soaking
through the steps and into the grease pit area where they can
cause lubrication problems.
While your cleaning crew is
busy polishing your escalator’s handrails and cleaning the
glass, make sure that they aren’t neglecting the stairs
themselves. Investing in an escalator cleaner, running it
according to the manufacturer’s instructions, and using it on a
regular schedule will go a long way toward making your escalator
the high point of your facility.
