2. Soil preventative actions

Prior to installation it is important to establish an effective cleaning zone in order to stop the ingress of dirt and soil. This will protect the floor covering and reduce cleaning costs.

The cleaning zone from outdoor areas should start with scraper mats in order to stop the drag-in of coarse particles. After this a barrier mat will absorb moisture and smaller particles. This should also be placed at high traffic points such as between factory and office, between kitchen and restaurants and also in the elevator area.

The most efficient cleaning zone should have a length of at least five metres. You should vacuum-clean the cleaning zones daily with a rotating brush and ensure that basic cleaning is made at regular intervals in order to maintain a maximum absorption of moisture and dirt.

3. Vacuum cleaning

The purpose of vacuum cleaning is to remove all loose dirt types and dust. Entrances and corridors should be vacuumed daily even though the areas are not visibly dirty. Plan the vacuum cleaning in order that high traffic point areas are vacuum-cleaned most often.

Vacuum cleaners mounted with a rotating mouth brush are recommended. The mechanical effect of the brushes is effectively loosening dirt and particles from the pile.

Filters: Use a vacuum cleaner with a good and efficient HEPA-micro filter system in order to be able to remove fine dust and maintain a good indoor climate. The HEPA filter system, which has been developed in co-operation with the Asthma and Allergy Association extracts 99,997% of pollen, dust, animal scales and other particles.

Recommended vacuum cleaners: Use a vacuum cleaner with an effective absorption capacity. The vacuum cleaner should have an effective micro filter system in order to be able to remove fine dust and maintain a good indoor climate

4. Cleaning at intervals

Cleaning at intervals can be regarded as a less thorough cleaning, where the appearance of the carpet is freshened up at regular intervals. Cleaning at planned intervals is an excellent cleaning method for carpets with light or medium soiling. This type of cleaning involves the methods and procedures described as:

a. Chem-Dry® method
b. Combi - cleaning
c. Extraction method
d. Dry-cleaning

a. The Chem-Dry® method involves brushing in a hot (60-75 degrees) pH neutral heavy carbon dioxide aqueous solution, which is subsequently absorbed and dried with a cotton disc.

Advantages:
  • extremely efficient cleaning
  • small quantities of water used
  • no soaking of the backing
  • no use of chemicals
  • the dirt is mopped from the carpet pile
  • short drying time (typical 1 hour)
  • minor risk of mistreatment
  • method and agent with a minimum load on the indoor climate
  • carpet stays clean longer, as there are no remaining concentrations of dirt attracting soap or chemicals.

Procedure: vacuum cleaning - spraying of carbon dioxide solution - absorption of dirt and moisture with cotton discs - possibly stain removal - drying.

b. Combi - cleaning involves cleaning with vapour in a custom-built brushing machine (Lux Professional). Two reverse rotating brushes loosen the dirt, which together with the cleaning water is lead via a conveyor belt into a drain tank. The machine uses small quantities of vapour / water, which results in short drying times.

**Instead of vapour, clean water can be used; however, this will increase drying time**

Advantages:
  • very efficient cleaning
  • small quantities of water
  • no soaking of the backing
  • no use of chemicals
  • short drying time (typical 1- 2 hours)
  • minor risk of mistreatment
  • method and agent with a minimum load on the indoor climate
  • carpet stays clean longer, as there are no remaining concentrations of dirt attracting soap and chemicals.

Procedure: vacuum cleaning - brushing treatment - possibly stain removal - drying.

c. The Extraction Method is carried out by spraying a cleaning solution into the carpet pile. After a short period of action a rinse with clean water is made and absorption of the cleaning solution and dirt.

Advantages:
  • moderately effective cleaning
  • the use of an extraction machine alone gives good removal of loose dirt but may not remove more difficult stains
Disadvantages:
  • larger quantities of water required
  • longer drying times required (typical minimum 24 hours)
  • risk of mistreatment
  • the use of a cleaning solution (chemicals)
  • risk of remaining concentrations of dirt attracting soaps and chemicals.

Procedure: vacuum cleaning - spraying of cleaning solution - short wait - 2 - 3 times rinsing with clean water and absorption - ending with 1-2 times absorption - drying.

d. Dry-cleaning is an alternative cleaning method which can be applied where there is no time for the carpet to be allowed to dry before being walked on again.

Advantages:
  • moderately effective cleaning of visible dirt
  • no drying times
  • the carpet can be taken into use immediately after cleaning.
Disadvantages:
  • dry-cleaning can have an influence on the air quality during and after execution
  • effective air circulation is a must
  • immediately after dry-cleaning small quantities of the dry-cleaning agent may be left in the carpet, which demands repeated vacuum cleanings before they are fully removed.

Procedure: vacuum cleaning - pre moisten with pre spray - spread the dry cleaning agent - brushing - drying - vacuum cleaning with a mouth brush.

5. Basic cleaning

The purpose of basic cleaning is to achieve a more thorough cleaning of the carpet. The method is used for periodic cleaning where the carpet has become somewhat or very dirty. Basic cleaning can be carried out by using methods and procedures following:

e. The Chem-Dry® method for basic cleaning involves the use of the PowerHeadTM AXT technique, which injects a 60-75 degree hot pH-neutral heavy carbon dioxide aqueous solution through 550 jets per minute. The carpet is at the same time manipulated with 550 mechanical steps per minute. Absorption is made with a combination of heavy vacuum through 5000 suction planes per minute and a mechanical fluid flow through the carpet. After this the pile can be dried with a cotton disc if necessary.

Advantages:
  • extremely efficient cleaning
  • small quantities of water used
  • thorough but no soaking of the backing
  • no use of chemicals
  • the dirt is mopped up from the carpet pile
  • short drying time (typical 1 - 2 hours)
  • minor risk of mistreatment
  • method and agents with a minimal load on the indoor climate
  • carpets keep clean longer, as there are no remaining concentrations of dirt attracting soaps and chemicals.

Procedure: vacuum cleaning - spraying of a carbon dioxide solution and absorption of dirt is made during one work routine - possible drying with cotton discs - possible stain removal - drying.

f. Combi-cleaning for basic cleaning involves cleaning with vapour from a custombuilt brushing machine (Lux Professional). Two reverse rotating brushes loosen the dirt, which together with the cleaning water is lead via a conveyor belt up to a drain tank. The machine uses small quantities of vapour / water, which results in short drying times.

** In heavily soiled areas, water can be used instead of vapour with a small quantity of lowfoaming carpet cleaning agent added.**

After rinsing with clean water, absorption with an extraction machine might be necessary in heavily soiled areas. The use of water, however, will prolong drying time.

Advantages:
  • very effective cleaning
  • small quantities of water
  • no use of chemicals
  • short drying time (typical 1-2 hours)
  • minor risk of mistreatment
  • method and agents with a minimum load on the indoor climate
  • the carpets keep clean longer as there are no remaining concentrations of dirt attracting soaps and chemicals.

Procedure: vacuum cleaning - brushing - (rinsing with water - absorption with the extraction machine) - possible stain removal - drying.

6. Treatment

Your Westex Carpet has been treated against soil and stains at our factory and cured during the manufacture of your carpet. This secures good resistance to wear and cleaning. The stain resistant treatment will last for the life of the carpet.

7. When the cleaning is finished

Check your carpet for possible remaining stains, which were not removed during the cleaning process and treat them accordingly.

Do not walk on your carpet again before it is completely dry. The carpet also has to be quite dry before furniture is put back in place, as chair legs and similar may rub off on the wet carpet.

8. Stain removal

Usually stains emerge after spillage's or by set-off from soles of shoes. The stains should be removed immediately. No matter which type of carpet you have chosen the following "first aid" should be a good guidance.

Do not walk on your carpet again before it is completely dry. The carpet also has to be quite dry before furniture is put back in place, as chair legs and similar may rub off on the wet carpet.

a. First aid

  1. 1. Remove loose dirt. In case of fresh stains, first remove loose remains and spilled fluid should be absorbed with a dry cloth or white paper towel. Do not rub but dab the stain away. Dried-up or concentrated stains are treated with a brush and vacuum cleaner.
  2. 2. Lukewarm water. Dissolve with lukewarm water without soap, detergent or the Dab carefully the area with a wet cloth and absorb as much of the moisture as possible by “dabbing” with a dry cloth. Then sprinkle with corn starch and leave to dry for 24 hours before vacuum cleaning.
  3. 3. Carpet stain remover. If water is not sufficient to dissolve the stain go on with a universal stain remover. See the instructions on the packing. In order for the stain not to spread or to be pressed deeper into the carpet the stain remover has to be removed again by “dabbing”. Remember to dab with clean water and afterwards dab with absorbent material in order to remove all residues of the carpet stain remover.
  4. 4. Use special agents. If none of the three above steps of the “first aid” are successful, treatment with special agents is required. Observe the directions for use and dosage carefully and never treat humid areas, leave them to dry first. If there are rims after the treatment the carpets is generally dirty and needs to be cleaned. If the stain emerges again there are either residues of the carpet stain remover or of the stain. You will have to treat the area again as described under step 3.

The first time a cleaning agent or stain remover has to be used on your carpet it must to be examined to establish whether the agent is harmful to the carpet. Damages may occur as a consequence of colour bleed, discoloration, bleaching or dissolution. It is recommended to test the stain remover in an inconspicuous area (a corner, under a radiator etc.). The test is to be made according to the prescribed dosages and action times.

Important

Always work on the stain from the outer edge towards the middle. To avoid the cleaned area becoming rapidly soiled again ensure good rinsing and removal of the remaining stain remover.

When removing stains from larger areas the use of an extraction machine is recommended. The faster action is taken towards stains the greater chance of removing them. Please note that some types of stain are very difficult to remove and that such stains will be more visible on a light, plain coloured carpet than on a darker and more patterned carpet. Some types of stains e.g. coffee, tea, soft drinks and red wine may still be visible after cleaning with a universal stain remover or a special agent because of colour residues. Such colour residues can often be removed successfully with a special bleaching product (see our description of special agents following).

WARNING!

NEVER use chlorine-containing products as there is a risk of bleaching your carpet.
