There's been a lot of talk on here recently about wfp not being all its cracked up to be. In this fast moving world I'm sure the next innovation is just around the corner that will 'revolutionise' window cleaning the same way wfp did.
Watching TV last night I saw a long advert for the HD steam cleaner, where they were steam cleaning windows.
Got me thinking if this was possible on a large scale, using pure water, so a 'pure steam' cleaner so to speak. No brushes, maybe just a soft pad to scrub any stains, and let the steam do all the work. It would literally melt almost everything off the glass whilst using a lot less water to clean.
Although I'm not sure if this method would be safe to use on the rubbber seal around the edge of the window, perhaps some sort of guard would solve this.
I wonder if anyone else has any ideas or predictions on what the future holds..
