Regular cleaning is important to remove potentially harmful contaminants and debris, and to maintain a healthy indoor environment, but numerous chemicals, together with improper cleaning techniques, can undermine air quality. The increased focus on workplace health and wellbeing and the introduction of standards, such as the WELL Building InstituteTM framework, has therefore put many traditional cleaning chemicals under the spotlight.
Chemical free cleaning with stabilised aqueous ozone is not a new concept, but improvements in the technology and a reduction in the size of the equipment needed has now made it feasible for most facilities. The process relies on the fact that ozone is a powerful oxidising agent, which when dissolved in water produces a broad spectrum biocide that destroys bacteria and viruses, as well as removing dirt, grease and mould. Oxygen from the air is converted into ozone by electricity within the preparation unit and infused into ordinary tap water. The stabilised aqueous ozone leaves the dispenser to fill all cleaning equipment from auto scrubbers and buckets to trigger sprays, and remains effective as a cleaning agent for 24 hours.
- It eliminates the use of cleaning chemicals that contribute to health problems and impact air quality.
- It is a sustainable alternative to chemical cleaners, which is equally effective, odourless and leaves no residue.
- It is effective against bacteria such as E.coli, streptococcus and MRSA.
- It is completely safe to use, converts back to water and oxygen, and avoids chemicals being discharged into watercourses.
- There is no need to transport, store, mix or dispose of chemicals.
Now for the really clever bit! Ozone owes its biocidal effectiveness to its ability to oxidise organic materials in bacterial membranes, which weakens the cell wall, leading to rupture and immediate death of the cell. In contrast, chlorine, and other oxidising and non-oxidising biocides, must be transported across the cell membrane in order to interfere with either the nuclear reproductive mechanism or enzymatic reactions in the cell, either of which results in substantially less biocidal efficiency.
