Do not use laundry detergents
or dishwashing soaps with
degreasers. For liquid cleaners,
use approximately 20 drops
per 3.78 L (1 gal) of water.
A concentrated soap solution
will leave a residue that creates
streaks and attracts dirt. Do not
use solutions that contain strong
or caustic soap.
Do not heavily saturate the
upholstery when cleaning.
Do not use solvents or cleaners
containing solvents.
To clean, use a terry cloth fabric
dampened with water. Wipe droplets
left behind with a clean dry cloth.
Commercial glass cleaners may be
used, if necessary, after cleaning
the interior glass with plain water.
Start by vacuuming the surface
using a soft brush attachment. If a
rotating brush attachment is being
used during vacuuming, only use it
on the floor carpet. Before cleaning,
gently remove as much of the soil
as possible using one of the
following techniques:
Gently blot liquids with a paper
towel. Continue blotting until no
more soil can be removed.
For solid soils, remove as much
as possible prior to vacuuming.
To clean:
1. Saturate a clean lint-free
colorfast cloth with water or club
soda. Microfiber cloth is
recommended to prevent lint
transfer to the fabric or carpet.
2. Remove excess moisture by
gently wringing until water does
not drip from the cleaning cloth.
3. Start on the outside edge of the
soil and gently rub toward the
center. Fold the cleaning cloth to
a clean area frequently to
prevent forcing the soil in to the
fabric.
4. Continue gently rubbing the
soiled area until there is no
longer any color transfer from
the soil to the cleaning cloth.
5. If the soil is not completely
removed, use a mild soap
solution followed only by club
soda or plain water.
