Sharing Information, this is only a guide and is collated from various unconfirmed sources. We have checked the details as far as possible but hold no responsibility for its accuracy. You will have to confirm your own research on any particular term.

Alkalinity - Alkalinity is useful in removing acidic, fatty and oily soils. Detergent products can be formulated at any level of alkalinity to meet cleaning performance requirements.

Antistatic Floor polishing - Conductive Flooring - A type of floor which is constructed to form a pathway of moderate electrical conductivity between equipment, people and the floor. This floor is designed to prevent the buildup of hazardous electrostatic charges in areas where flammable gases are used. The resistance of such flooring must be maintained between 25,000-100,000 ohms. Special polish and maintenance products are available for this flooring.

Autoclave - An instrument that is pressurized by steam, without the inclusion of air, in which articles and/or liquids may be sterilized.

COSHH - COSHH is the law that requires employers to control substances that are hazardous to health. You can prevent or reduce workers' exposure to hazardous substances by: finding out what the health hazards are; deciding how to prevent harm to health risk assessment; providing control measures to reduce harm to health; making sure they are used; keeping all control measures in good working order; providing information, instruction and training for employees and others; providing monitoring and health surveillance in appropriate cases; planning for emergencies.

Contact Time - The published time that a disinfectant or sanitizing chemical must remain wet on the surface being treated. These chemicals are killing germs only when wet.

Pine Oil - Oil processed from gum trees, used in hard surface cleaning and disinfecting.

pH scale - measures how acidic or Alkaline a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is Alkaline.

Risk Assessment – A Risk Assessment is a systematic method of looking at work activities, considering what could go wrong, and deciding on suitable control measures to prevent loss, damage or injury in the workplace. The Assessment should include the controls required to eliminate, reduce or minimise the risks. For general office cleaning this means assessing the hazards, methods and precautions of each particular task in a specific work place. See

Rotary Carpet Cleaning - A carpet cleaning technique in which a detergent solution is worked into the carpet pile by a brush or bonnet mop attached to a rotary slow speed (Aprox 150rpm)machine. Loosened soil is usually removed by vacuuming, commonly called shampooing.

Floor buffing and spray cleaning 300-400 rpm. Burnishing 400-800 rpm and ultra high speed burnishing 800–1500 rpm. Some specialised burnishers range from 1500-3000rpm These are usually gas or battery powered.

Scrubber Dryer – Machine with a cylindrical or rotary brush that will spray a chemical onto a floor, agitate the liquid then suck the soil back into a holding tank, leaving the floor clean and dry.

Shelf-life - Length of time an undiluted product can remain active and effective. Light, temperature, organic matter and metals can affect chemical stability.

Spray Buff - An intermediate floor care procedure which cleans, removes black marks and shines the wear areas of the floor. Utilises a sprayed solution, a floormachine and a synthetic floor pad.

Spray extraction – This is the process associated with carpet and upholstery cleaning machines. The method is to spray a diluted chemical under pressure in to a carpet. It is followed by sucking up the chemical and soil in to a holding tank by vacuum. Usually done in one process by the same machine. Pressures vary from 40 to 500 psi dependant on the machine. 70-100 psi is normal.

Steam cleaning – Using a machine that heats water to about 120ºC. This is then expelled under pressure on to the surface to be cleaned. This term is often given to Spray extraction which is a different process.

Sterilisation - Process of killing all forms of microbial life including fungi, viruses, spores and vegetive bacteria.

Strip and Seal – To remove old seal from a floor with chemicals or by mechanical means i.e. sanding. A suitable seal is then applied to the floor surface, to enhance the look and act as a hard wearing sacrificial surface to protect the original floor surface from wear. Floor Seals are often Polyurethane like varnish or oleo resinous. Floor polish is often applied on top of seals to further protect the floor.

Strip and Polish - To remove old polish from a floor with chemicals. A suitable polish is then re applied to the floor surface. It will enhance the look and act as a sacrificial surface to protect the original floor surface from wear. Floor polish is usually a water based emulsion of polymers and waxes that can easily be removed with the right floor polish stripper.

Sulphamic Acid - Is frequently used for removing rust and lime scale. It is used in good quality toilet and washroom cleaners with a blend of other chemicals. This can replace the more volatile, irritating and damaging hydrochloric acid. When compared to most of the common strong mineral acids, Sulphamic acid has desirable water descaling properties, low volatility, low toxicity and is a water soluble. It will vary in strengths from 3-15%

Sulphuric Acid - Highly corrosive acid made from sulphur dioxide. Used in drain opener chemicals. This is a dangerous chemical and all instructions and safety measures must be adhered to.

Surfactant - Surface-active ingredient that increases foaming, dispersing, spreading, emulsifying and wetting properties of a product.

Polish Undercoat – Micare Basecoat Is applied to a porous floor surface such as linoleum to seal the floor prior to applying floor polish.

Use-life - Length of time a diluted product can remain active and effective. Stability of the chemical as well as the storage conditions determine the use-life of antimicrobial products.

Viracide - A chemical agent that kills viruses.

Wetting Agent - A Chemical which allows water to spread more freely.
