Stain Guide
In principle, stains should be dealt with as soon as possible
after they occur.
As more than 90% of all stains consist of residues from sugary
drinks, attempts should first be made to remove the stains with
luke-warm, clear water. Sugary drink stains can be dealt with in
this way: Work the stained area with a wet cloth, sponge or
brush. Avoid rubbing on delicate surfaces with a pile. If the
stain substance is not removed by this, however, use normal
stain removal agents. Dirt which resists removal should
first be carefully loosened using suitable equipment (back of a
knife, spatula or spoon), without damaging the pile, and the
loose substances should be vacuumed up.
Before using carpet cleaning agents or specialist dry cleaning
materials, the carpet should be tested in an inconspicuous spot
or on an off-cut for colour-fastness.
Dirt containing oil or fat can be removed using suitable carpet
cleaning agents or stain removers.
For marks covering a large surface area, intermediate cleaning
methods can be used.
Use of washing-up liquid or gentle detergents, etc., is not
recommended, as this increases the risk of repeat staining of
the covering due to residues.
Soil such as tar, asphalt, felt-pen ink, glue or paint can only
be removed using organic solvents. When using these solvents,
health and environmental protection directives must be followed.
If possible, products with a water-soluble solvent (e.g., based
on diethylene glycol ethers), which are not regarded as
hazardous substances, should be used.
Please note: Dissolved stain substances and, when relevant,
stain removal agents must not remain in the textile floor
covering in order to avoid the same stain recurring or
unnecessary repeat staining. Attention must always be paid in
such cases to rinsing thoroughly with water and then draining
(wet vacuuming, extraction).
Specific stain treatment
Chewing gum Liquid agents â€" generally based on
citrus-turpentine â€" are very well-suited to simple removal of
chewing gum. Freezing sprays used to be offered as chewing gum
removers, but these contained ozone-layer destroying
chlorofluorocarbons (CFCs) and were therefore taken off the
market. Rust Removal with 10% oxalic acid solution (available
from chemists as "salts of lemon"). After treatment, the
covering must be thoroughly treated with clear water. Blood
Removal using products containing enzymes; let work overnight. A
"rust stain" often remains from blood stains, due to its
haemoglobin (iron content); this can be removed with 10% oxalic
acid. Urine Removal using products containing enzymes; let work
overnight. Acid Removal with varnish solvent paste based
solvent. Caution with coverings sensitive to alkali! Mould
Remove with 6% hydrogen peroxide solution (chemists). Soak a
cloth in the liquid. Let work overnight. Caution due to
bleaching effect and fading of dyes! Ink Removal with sodium
dithionate solution (specialist, chemists). Test in unobtrusive
spot first!
Fruit Removal with enzymes, oxidation or reducing agent. Test in
unobtrusive spot first!
Candle wax Remove using a hairdryer. Place a coffee filter paper
on the stain and warm the spot carefully. Remove any residue
with solvent. Other method: flood stain with hot water and treat
spot immediately with a wet vacuum.
Shading Shading is the term for stains which arise without the
effect of dirt substances. While these look like seriously
stained marks (similar to a large drink spill), their cause is
really due to the pile of the textile covering being irregularly
displaced.
The phenomenon occurs in all kinds of fabrics and goes from one
room into another. The effect can also extend over several
storeys, with the affected areas lying precisely one above
another.
The scientific causes of this have not yet been determined.
Shading cannot be removed by cleaning!
Burn marks Burn marks cannot be removed by cleaning. The
affected part of the textile covering must be replaced
