Window cleaners no longer have to hang precariously from a ladder wielding a cloth. With extendable hoses, brushes and jet washers, window cleaning has moved on to a more efficient level of execution.

On some modern buildings it has moved a step further in that there is even self-cleaning glass which does not require as much cleaning as its predecessors. However, even that comes with challenges as not all self-cleaning glass is made the same. Some might require knowledge of how hard or soft the local water is, and great care should be taken not to scratch any of the protective coatings.

Green cleaning

With the elevated demands to keep our built environment scrupulously clean because of the coronavirus, the big question of the moment is: can we continue to deliver exemplary service whilst maintaining green practices?

The answer is yes, because not only is our machinery smart, but our cleaning agents have become smarter as well. It is possible to deep clean and cause less detrimental effect to the environment while doing so.

We can dispose of greener cleaning chemicals safer in the knowledge that they won't necessarily tarnish the water supply, or ruin the microbial filtration ecosystem of sewage plants, for example. It wasn’t that long ago that percoethylene fluid used by dry cleaners was shown in some cases to disrupt sewage treatment, and cause dirty water to be pumped back into the water supply because purification was interrupted by the chemical.

Also consider alternative cleaning agents like Stabilised Aqueous Ozone, which is a water-based cleaner that kills

99% of bacteria. Water is charged with electricity thereby converting the oxygen molecule from O2

doesn't expel any harsh chemicals upon disposal. to O3

There are also bonding microbial shield treatments made from 99% de-ionised water, which require infrequent application but can remain active against viruses for up to a month. Many mechanical floor cleaners are much more water efficient using very little to achieve maximum cleaning. Many are rechargeable too, saving on energy use.

In short, there are now many innovative solutions which enable us to clean effectively and sustainably.


The overall point that I want to convey is that the solutions exist for us to continue as an industry with a strong, sustainable profile. By sustainable I mean safeguarding the longevity of our businesses – it may take a little rejigging and a small change in our individual service profiles, but we can prevail. It also means that we can positively impact the economy and workforce with our input, as well as the social wellbeing of the end-users around us.

As for responsible cleaning practices, the innovation exists for us to maintain them while taking care of our world, protecting our water supplies and tables, not defiling our soils or adding any toxicity to our built environment.

Where some of us might have been reluctant to actively pursue these paths before, I think now we are compelled to explore every responsible option that there is so that we can weather the crisis together, and proceed into the future knowing that we have left an honourable legacy behind us.
