If there is parking or other vehicle traffic near the
doors, we must consider leakage from the automo-
bile engines. Engine oil, brake fluid, anti-freeze and
transmission oils will be deposited over time and
must be removed. Not only is this unsightly, but
eventually these oil spots will attract dry soils and
start their approach to the front door. Oil absorbent
can be used as a poultice to bring oil stains to the
surface, where they can be removed. Dry granular
absorbents are best for outdoor work and work best
if left on the spot for several hours or days depend-
ing on the severity of the spot. These spots can also
be pressure washed, using strong degreasing
agents. Again, watch for the run off, but there are
several pressure washing tools with vacuum contain-
ment, such as the Hydroforce SX-15.

The real key to providing great outside service of de-
bris removal is to understand the surfaces you will be
working with. Everything from concrete driveways,
asphalt parking surfaces, paver block walkways and
natural stone outer lobbies are found in buildings.
Having a good working knowledge of each surface
type is necessary to develop long term maintenance
strategies.

mat should be able to withstand the elements and
have someplace for the dirt to drop into so that it
does not get contaminated and start doing the oppo-
site of what it was intended to do. The inside mat
