CLEANING TIPS
x Check the condition of the carpeting. If the carpet is loose, heavily soiled,
stained, spotted or badly worn, point this out to the person in charge.
x Locate an inconspicuous spot on the area to be cleaned. Test carpet for
colorfastness before proceeding. Pour the concentrated cleaning solution on
the spot, cover with a white towel and place a heavy object on top to absorb
the cleaning solution. Wait 10 minutes for any reaction to take place.
Remove weight. If there is no color transfer, it should be safe to clean.
x Remove the furniture from the area to be cleaned. Large pieces can be
moved to opposite end of the room from where you start cleaning and replace
when it is completed. After cleaning carpet, place a small square of
aluminum foil or 6-mil poly square under the furniture legs to prevent moisture
from damaging the finish or rusting the metal glides.
x Clean the area first with a Clean-Air Carpetkeeper, upright vacuum. Do not
use the Marathon 2000 as a dry vacuum! Heavily soiled carpet or areas of
concentrated foot traffic should be treated with recommended pre-spotting or
pre-spray chemicals, using a hand spray trigger bottle or pump up sprayer.
Do not allow any spotter or pre-spray to dry on the carpet.
x Identify the type of carpet fiber to be cleaned. Most commercial carpet fibers
in use are nylon or acrylic based. Best results in cleaning would be obtained
if hot water is used to clean these types of fibers. On the other hand, hot
water could shrink natural fiber carpeting, like wool and cotton in particular.
Exercise caution when cleaning natural fibers. Use cool water test for
colorfastness and apply the least amount of cleaning solution possible.
x Plan your cleaning route. Always try to have the cord to the right of the
Marathon 2000 extractor so you are working away from the cord. Operate the
extractor in parallel passes. Clean the perimeter last. Turn “off” spray switch
in turns to conserve cleaning solution.
x To decrease dry time, go over the carpet without pressing carpet spray
switch. To further decrease the drying time, use the Windshear 3000 Carpet
Blower.
x When running the Marathon 2000
extractor, do not overfill the recovery tank.
Do not allow the water level to rise above the clear dome on top of the
recovery tank.
x If the spray jets become clogged, remove the spray bar assembly or the
individual spray tips and soaks them in a mild acid or anti-browning chemical
to dissolve normal alkaline chemical buildup.
x When the Marathon 2000 extractor runs out of cleaning solution, as noted by
streaking or incomplete cleaning, turn off the machine and drain the recovery
tank. Refill as needed and continue cleaning.
