Clean Room Floor Deep Cleaning


Cleaning in highly sensitive environments such as clean rooms adds a further challenge to what is often already a difficult task.

The sensitivity of the environment is closely monitored and controlled to avoid any contamination entering into the working environment as well as ensuring containment.
















Pressure controlled changing areas are provided to ensure contaminants are not transported either way. All equipment needs decontamination prior to entering the clean room.

This all adds to the amount of effort and energy expended when the task of deep cleaning the floors arise. Most clean room flooring is vinyl, which is sealed with a removable polish.

Stripping off the old polish and deep cleaning vinyl flooring is a tough and highly skilled job. If it is not completed to a good standard, it shows in the finished product.


Another big challenge when stripping floor polish off in these environments is that rarely will there be access to water and waste facilities. So each time fresh water or soiled water waste needs to be replenished or disposed of, operatives will have to go through the changing process moving from the clean room area to outside areas.

The process involves putting on and taking off, gowns or full body suits. Protection of the head and facial hair with hair nets. Cleaning hands with a sanitise solution and wearing protective gloves and shoe covers.

Of course, when wearing all that protective clothing and doing the very physical task of deep cleaning vinyl flooring it makes the work very hot and uncomfortable

One other challenge can be the effect of the air pressure on the works in progress. The process for stripping off layers of old polish begins with pre soaking the floor with a chemical solution of floor polish remover diluted in water.

For the chemical in the solution to be active, the floor must remain wet. The air pressure can accelerate the drying of the stripper solution, so it is very important to ensure the floor section not only being worked upon but the next section as well is kept wet.

Once the chemical has been active upon the floor for some time, normally a minimum of 20 minutes on a lightly polished floor and up to an hour on a heavily polished floor. The polish should be soft enough to clean off using a rotary floor machine.

A weighted machine will be best as extra weight can be added or removed depending on how stubborn the seal or polish is.


Once the floor polish has de-bonded from the vinyl floor surface by the agitation and scrubbing, the slurry solution left on the floor then needs to be removed with the use of a powerful wet extraction vacuum

Having removed the polish from the surface the next stage is to ensure the floor is then fully neutralised and no residue or chemical remain.

The best method is by wet mopping the floor several times. During the mopping process as soon as the water starts to get a bit cloudy it must be refreshed.

Once the floor is then clean and has dried the new polish or seal can be applied.

Two coats of a good brand polish applied should give the floor a good seal and leave the appearance fresh and vibrant.

The best method to apply the polish is using a flat mop and ensuring the polish is applied evenly.

The first coat should be applied in one direction across the floor. When that has dried and the floor has been left for a suitable time period the second coat can be applied in a cross direction from the first.

This should ensure that the floor get fully covered leaving no bare spots.
