Can you remove the rust stains
from my concrete?.
The short answer is a resounding maybe. Rust removal is a tricky thing
because depending on what caused the rust, how long the rust has been
there, and the unique attributes of that particular pour of concrete,
can all play rolls on how successful a rust treatment can be.
Good results can usually be attained from treating irrigation rust
stains from well water. These types of rust stains can either be
completely removed in most cases, or at the very least, almost
Rust stains from rusting objects like a decaying car parked on the
driveway, or a piece of iron furniture on the back porch, can usually
be successfully removed as well. These can tend to be a bit more
stubborn than the well water variety, but the results from treatment
are still usually worth it.
The worst, and what
we've found to be the most stubborn of all the rust
stains commonly found on concrete, are rust stains from fertilizers.
Often times they will almost be mistaken for mold or algae because
they are usually a darker brown to almost black sort of color as
opposed to an orange color. These are most often caused by fertilizer
granules being left on concrete and soon after the concrete getting
wet. After making contact with the water, the iron in the fertilizer
will then oxidize leaving a small rust spot on the concrete.
Another common area that we see fertilizer rust stains, is at the base
of potted plants that are placed on concrete. when the pots get
watered, the leaching water from the base of the pot (which may have a
lot of iron in it from fertilizers or even the soil its self) will
leave rust stains usually in a ring pattern under the pot. These can
be very unsightly and the results from a rust treatment are usually
limited, so the best rule of thumb is not to let it happen to to begin
Another aspect to consider about treating rust stains is that the
chemicals used in the treatment process will also brighten the
concrete. This is usually considered a benefit more so than a problem
because it can make your concrete look 10 years younger, or even like
it was just poured the day before. Because of this brightening affect,
the downside is the whole concrete area must be treated (rust stains
or not) otherwise you will end up with patch work of brighter shades
of concrete where the rust treatment was done.
As a side note: Concrete brightening is a stand-alone service that
we can do whether there are rust stains or not. It can really add a
wealth of curb appeal to a concrete driveway or other concrete area.

In most cases, our basic package for
concrete cleaning will be all you will need. This service includes
pressure washing the concrete using our surface cleaning machine, followed
by a surface treatment to help eradicate any mold, algae, and mildew that
wasn't removed by the pressure washing process. The surface treatment is
also very important because it will insure that the mold, algae, and
mildew spores, that can be deeply embedded in the concrete substrate, will
be completely removed which will help to keep the concrete clean for much

What about oil
like rust stains, can be difficult to completely remove from bare
concrete. The success rate for removing oil stains is also dependant on
multiple factors such as: how long has the oil been on the concrete? What
are the characteristics of the concrete (is it smooth, how porous), and
what kind of oil it is. Depending on these particular characteristics of
the concrete, the longer the oil stain is left on the concrete the more
limited the results will be. If the stain is treated immediately it can
usually be completely removed, or at the very least, to a faint shadow.
