Upholstery Maintenance

Coach seats are lightweight, with foam-padded
backs and cushions. For both appearance and
durability, best results are obtained if upholstery
is cleaned at regular intervals before dirt, dust
and grit have been ground into the fabric. Seat
fabric is made of 50% wool, 33% cotton, 9%
nylon, and 8% acrylic.
Routine Cleaning
•
All that is required to remove the dirt is a gentle
beating with the hand or the back of a brush.
This will bring the dirt to the surface where it is
easily removed with a vacuum or brush in the
direction of the pile which can easily be
recognized by running a hand lightly over the
pile. If the fabric becomes excessively dirty,
particles of grit will cause gradual wear, reducing
the life span of the fabric.

Dry Cleaning
•
If covers are to be removed for cleaning, dry
cleaning is recommended since washing might
cause some shrinkage, preventing the covers
from being reapplied to the seats without
damage. Other than spot cleaning the covers
while they are in place, dry cleaning is not
recommended, since the resulting fumes could
be hazardous in the confines of the coach and
the solvent could be detrimental to the foam
padding of the seats.
Cleaning With Covers in Place
•
The most effective and economical method to

clean the fabric seat covers is by washing with
either an approved foam upholstery cleaner or
with a mild household detergent.
Thoroughly vacuum the upholstery. Remove any
spots or stains before the seats are washed to
avoid a cleaning ring.
Dilute household detergent or liquid foam
cleaner according to directions on the container.
