Traditional methods of gum removal include scraping,
power washing, freezing, sand blasting, laser burning.
All of these methods have there pit falls. In fact some
of them create pits, even in concrete and particularly
in asphalt. GumFighters method far out performs all
of these methods.
Power Washing: This is probably
the most common method used. Due to the high volume
of water, it can only be used outdoors. Large amounts
of water are disbursed through a hose attached to a
wand under very high pressure, normally ranging from
1200 to 3500 PSI. Depending on the type of surface being
cleaned, this high pressure can damage the surface.
Many local ordinances are now requiring the operators
to reclaim the water being using by a vacuum system
so the large amounts of contaminated water does not
enter the drainage system. These machines are normally
very loud thus most of the cleaning must be during off
hours so as not to harm or inconvenience pedestrians
and customers. Some systems use hot water and harsh
chemicals as well. This process is very labour intensive
and normally does not remove all of the gum.
Scraping: A worker normally
uses a long handled scraper and physically scrapes the
gum off of the polluted surface. Paint scrapers are
used as well which causes the worker to be on their
knees while removing gum. This method is not normally
effective. This is also time consuming, laborious and
frequently damages the surface being cleaned. This method
is not suitable for soft surfaces such as carpets, rubber
and plastic tiles or surfaces prone to scratching. It
is not effective on rough to moderately rough surfaces
because only the surface can be removed leaving a black
sticky residue behind.
Freezing: This method involves
a heavily protected worker directing a jet spray of
carbon dioxide onto a gum spot. The carbon dioxide spray
freezes the gum and lifts it of the surface being treated.
This method is dangerous and not suitable for use in
areas where pedestrians or customers have access during
the operation of this equipment. This process is normally
conducted in the evening or off hours. This process
has caused damage to surfaces due to the extreme cold.
It is primarily used outdoors.
Sand Blasting: The key word
here is blasting. This process is only used outdoors
and is extremely messy. Sand and debris may be dangerous
to customers and pedestrians. This process is only used
in off hours. Requires expensive equipment and extensive
clean up. Due to the high pressure and sand used, it
normally damages the surface while removing the gum.

Laser Burning: This method
operates by using a laser beam to burn off the gum spot.
This method can not be used indoors or on surfaces prone
to burn. Normally operates in off hours due to the obvious
hazards. Normally expensive and has limited application.
Burning: This method uses
a propane torch to burn off the gum spot. As mentioned
in the Laser Burning, it is not used indoors and can
be very dangerous if not operated properly.
GumFighters: While our process
devours gum, the GumFighters method is gentle to surfaces
and safe for the environment. Our GumCart is engineered
to produce steam a high temperatures with low pressure,
using only 20-30 litres of water per day. Our proprietary
cleaning agent is a neutral chemical with a PH of 7.0.
It is extremely effective yet non-toxic. The small brush
at the end of the wand works carefully with the steam
and cleaning agent to disintegrate gum in seconds. The
operator exerts minimal pressure and uses different
brushes depending on the surface to be cleaned. Our
process works indoors as well as outdoors. We remove
gum from carpets, furniture, doors as well as footpaths,
walls and street surfaces during normal business hours
and business days.
