Disinfection
Destruction of disease-causing small creatures, like micro-organisms. (See:Bacteria, yeast plants, moulds) and viruses. Every cleaning step achieves a killing or at least a reduction of micro-organisms. For getting an absolute sterilisation special additional substances are needed for the formulation of a cleaning agent. These cleaning agents are checked, released and published by a neutral institution in lists (like e.g. "Deutsche Gesellschaft für Hygiene und Mikrobiologie (DGHM)" or "Deutsche Veterinärmedizinische Gesellschaft e.g. (DVG)".
KÄRCHER offers products for disinfection and combination products for cleaning or foam cleaning and disinfection.

Emission
Release and letting out of fine spread out substances in the air - e.g. out of internal combustion engines or chimneys. These substances can partly condense again by forming dust, dirt or oily films on surfaces (emission soiling, dirt, and condensation).
Floor coating
Application of protection and care coatings on cleaned hard floors. Coating agents are first of all polymer dispersions like Wet Look RM 741, RM 740 or RM 742 which are applied manually with a lambskin stripper. At the beginning old dirt and care agent coatings have to be removed. See:floor de-coating See:cleaning/basic cleaning. Then the floor has to be neutralised (See:neutralisation). After that, the manual coating can take place. For this, the floor should not be to dry, but also not to wet that the coating agent does not dilute and that there are no unnecessarily longer drying times necessary. The coating should almost always be put on thin and even. Uneven application leads to an irregular gloss. A too thick application causes drying disturbances - in extreme cases air-bubbles. There can be put on up to 3 coats according to the desired gloss degree. The drying time between the application of each coat takes 15 min. (depending on room temperature and atmospheric humidity). 30 min. after application of the last coat it can be walked on the floor. After 24 hours the hardening process is finished. Damaged coatings can be repaired by "Cleanern".
A care product can also be applied during maintenance cleaning by using a cleaning agent with care substances.
Floor de-coating
From time to time there are layers on hard floors of dirt and care product residues, which make the floor unsightly. Due to this, the coating has to be removed completely. This is carried our with floor scrubbers, hard scrubber tools and special cleaning agents (e.g. RM 752, RM 754).
There are two technologies:
1. Wet de-coating: This procedure functions like described above.
and
2.Dry de-coating: This process works without cleaning agents and little water. But it requires a high technical power and therefore a floor cleaning machine has to be used with hard brushes or pads (See:"Sinner´scher" cleaning circle). At start of work water has to be sprayed on the brushes/pads and parallel to this on the treated surface (max. 2-3 m_). This method offers the advantage to save cleaning agents and a neutralisation as well as its checking and an additional rinsing is unnecessary. However, one have to pay attention that sensible floors do not get damaged due to high mechanical stress (heat development can cause burnings in case of carelessness).
See:basic cleaning
Floor neutralisation
Neutralisation – before taking certain floor care steps like coating or crystallisation, the floors have first of all to be cleaned (See:basic cleaning) or de-coated (See:de-coating). This is normally carried out by the usage of strongly alkaline cleaning agents. Remains of alkalinity can even on dried floors lead to coating disturbances regarding its adhesion, drying, hardening or gloss. The crystallisation can be influenced, as alkalinity neutralises a part of the acid substances in the crystallisation agent and makes it ineffective. Therefore it has to be cared for that the floor is sufficiently neutralised after its cleaning. This is done by rinsing with clear water - possibly numerous times - until a pH-value from 6.5 to 7.5 is reached. For the neutralisation of alkaline cleaning agents one can also add a little bit of vinegar essence (=acid) to the wash water.
Acid cleaning agents are also neutralised by rinsing with clear water. We do not recommend adding an alkaline substance as caustic solutions either cause residues or smell strong.
Foam cleaning
2-step-HD-procedure on vertical/diagonal surfaces during which a running off is delayed due to foam production of a special nozzle set.
See:gel cleaning
Foam disinfection cleaner
foam cleaning with foam disinfection cleaner
See:foam cleaning, See:disinfection
Foam producer/Foam Star FS2000
Appliance which operates without compressed air (own compressor) for the production of foam. Preferably used in indoor areas like kitchens, butcher's shops and sanitary areas as it can be handled splash free on limited surfaces.
This machine can also be utilised for the application of gel cleaners, for pre-spraying (See:2-step-method) and for disinfection cleaning / disinfection / foam and disinfection cleaning.
Food area
in general similar procedures like sanitary objects. Very important in this region is the recognition of germs. See:disinfection
Gel
Pudding-like state of a substance. The gel structure makes a slow running off from vertical/diagonal surfaces possible. This means, a cleaning agent with gel structure dries slower and the reaction time between cleaning agent and dirt is longer.
Gel cleaning
Gel – The KÄRCHER gel cleaning agent RM 56 is a liquid when it is delivered. Only if you dilute it from approx. 8 to 20 % it converts into a gel structure which makes a slow running off possible. Here the slow running off is also very important like in case of foam cleaning. This is precondition for an exchange between cleaning agent and dirt at the border area.
Gel cleaning is principally carried out in the 2-step-method
The gel-cleaning agent RM 56 can in a low concentration also be used like a foam cleaner.

House dust allergy
House dust allergies, which are caused by mite excreta, can be fought effectively and lasting if you use special cleaning agents. Mitex RM 765 liquid is applied like RM 760 in the spray extraction. RM 766 moistly powder is brushed into the carpet and vacuumed after a reaction time of approx. 2 hours.
6 months protection against house dust mites.
