Fabric
General Maintenance:
Daily care and immediate stain removal will ensure that
your upholstery will keep looking good for many years to
come. It is normally suicient to regularly vacuum gently
with a so mouthpiece to preserve the fabric’s color and
appearance. To preserve the colors of the material, keep
out of direct sunlight.
Do not brush fabric or use a vacuum attachment with a
rotary brush. Brushing may permanently damage the nap or
change the character of the fabric.
Thorough Cleaning:
If further cleaning is needed, dry-clean or spot clean fabric
with solvent cleaner appropriate for specific fabric. Visit
manufacturers website or contact representative for best
solution.
Do not apply water or any liquid solution. Wetting the fabric
with any liquid solution may result in permanent damage.
Polyurathane upholstery
General Maintenance:
Daily care and immediate stain removal will ensure that your
upholstery will keep looking good for many years to come.
Leaving vinyl damp or in the sunlight for extended amounts
of time can make the upholstery susceptible to drying,
fading, and cracking.
Everyday Cleaning:
For normal cleaning, wash vinyl upholstery with a so cloth
or so-bristled brush lathered with mild, nonabrasive soap
and lukewarm water. Before the suace dries, wipe with a
clean, dry cloth to remove any residue.
Thorough Cleaning:
This procedure may be repeated to remove stubborn dirt
or stains.
Ink spots can sometimes be removed by washing with soap
and water followed by isopropyl alcohol.
Do not use any cleaning method that is not listed above,
as other methods may attack the vinyl and cause eventual
degradation.
Leather
General Maintenance:
Leather is an organic material that will change appearance
over time. Never place leather furniture closer than 20-30 cm
from a radiator, or in direct sunlight.
Everyday Cleaning:
Vacuum clean frequently with a so brush, and clean sur-
faces subjected to heavy wear, such as arm and neck rests,
as required. Water-soluble stains are easily removed by soa-
king and blotting with a so cloth.
Thorough Cleaning:
For spots and spills, wipe excess liquid immediately with a
clean cloth or sponge; let the leather air dry. If the spot is
still visible, further cleaning may be necessary. Sponge the
entire suace - seat, back, or chair arm - with clean, luke-
warm water. Let the leather air dry; never use a hair dryer or
other heat source to dry leather.
For stubborn spots and stains, apply a mild, nonabrasive
soap solution with a clean, wet sponge. Rinse well and let air
dry. For butter, oil, or grease, wipe the leather with a clean,
dry cloth and let the remainder of the oil dissipate into the
leather. Do not apply water or try to wash a grease spot.
Never attempt to remove problem stains with strong sol-
vents or chemical products - i.e. saddle soap, cleaning sol-
vents, oils, furniture polishes, varnishes, abrasive cleaners,
detergents, or ammonia on leather; this can ruin the finish.

PA (nylon, polyamide) and PP
(polypropylene)
General Maintenance:
PA is a durable plastic type, which is resistant against many
chemicals and solvents. Do not use acid or strong bases.
It is resistant to oil containing products, gasoline, fat and
alcohol.
Everyday Cleaning:
For normal cleaning, wash plastic suaces with a so cloth
soaked in mild detergent and warm water. Rinse thoroughly
and dry with a so cloth. Do not use solvents or abrasive
kitchen cleaners. In normal/daily cleaning use a dry cloth.
Light dirt can be removed with a damp cloth in lukewarm
water.
Thorough Cleaning:
For tougher stains use any mild solution of dishwashing
detergent and wipe with a hard-wrung wet cloth in clean
water and then with a dry cloth. Since PA is alcohol resistant,
you can ultimately use methylated spirit to remove dirt.
Metal (chrome, aluminium, powder
coated, etc.)
General Maintenance:
Coated metal products can scratch and scu. Use caution
when cleaning or moving products to avoid damaging or
scratching metal suaces.
Water can stain aluminum as well as cause damaged chro-
mium-plated and lacquered steel suaces to rust. To avoid
this, make sure metal items are kept dry at all times.
Everyday Cleaning:
Wash coated metal suaces with a so cloth soaked in de-
tergent and warm water; rinse thoroughly and dry.
For normal cleaning, apply a pre-soened paste wax to
polished aluminum components following the manufac-
turer’s instructions. Near salt water, apply wax once a month.
In other areas, apply wax once every three months to main-
tain appearance.
Thorough Cleaning:
Aluminum, chromium-plated steel can be wiped with a
cloth moistened with methylated spirits. CAUTION - fire risk!
Provide ventilation!
Remove scu marks from low-gloss coatings with pre-sof-
tened paste wax, following the manufacturer’s instructions.
Remove scu marks and scratches from high-gloss coat-
ings using automotive polishing compounds, either liquid
or paste. Aer polishing, apply a pre-soened automotive
paste wax to restore original sheen.
Compact laminate
General Maintenance:
The non-porous suace is easy to clean. The decorative
suace and resin core of Compact Laminate is impervious
and resistant to most commonly used cleaning agents and
disinfectants.

Everyday Cleaning:
Suaces can be easily cleaned with a dry or damp cloth and
if necessary, a mild household cleaner. All-purpose cleaner,
household cleaners, water or soap are recommended. It is
resistant to everyday wear and tear but needs some atten-
tion for harsh conditions and staining.
Thorough Cleaning:
Review suppliers’ instructions for further cleaning on diicult
stains. Do not use abrasive or polishing materials, abrasive
cleaners, scourer pads, bleaches, wire wool or sandpaper.
High pressure water cleaning or steam cleaning of panels is
not recommended. Don’t use any product containing strong
mineral acid such as sulfuric acid, battery acid, hydrochlo-
ric acid, nitric acid or phosphoric acid. Care must be taken
where cleaning agents or solvents are highly acidic or alka-
line as these may permanently damage the suace.
Veneer
General Maintenance:
Always protect suaces against heat, damp or color bleed-
ing objects. Do not place furniture directly against radiators
or heaters.
To preserve the colors of the material, keep out of direct
sunlight. In addition to light, extremely high or low humidity
is a damaging environmental factor.
Everyday Cleaning:
For basic cleaning use a clean, slightly damp, nonabrasive
cloth with cleaner formulated for wood furniture. Wipe dry
with a dry, so cloth in the direction of the wood grain.
Do not use aerosol-powered cleaners or polishes. Spills and
dampness should be cleaned promptly and not allowed to
air dry.
Thorough Cleaning:
Detailed cleaning should be completed at least once a
year. Apply a quality furniture polish with a clean, so cloth
to maintain the suace. Avoid using aerosol-powered
cleaners or polishes. Do not use polishes containing waxes
or abrasives, or oil-based polishes. Verify cleaner used is
appropriate for the type of wood to prevent changes to the
color of the wood or treatment.
Scratches can be repaired with the use of a scratch-remov-
ing polish the appropriate color for the veneer. If in doubt
about the suitability of a particular cleaner or polish, check
with the manufacturer of the cleaning product.
