There are different levels of pure water which we use. We refer to is as pure water, but its also referred to as ultra pure water and im sure most on here if not all on here know that ultra pure water is used in various ways, ours is to clean windows and not have to dry them because they dry clear as far as our eye sight is concerned. However dig a little deeper and its more than that. Also dependant upon its usuage their are different clarities of ultra pure water. Why does water clean so well and break down dirt and deposits on the window?? Why does hot water disolve more dirt easily?? Yes at end of day, simply because it does is good enough reason for most to just use it! However dig a little deeper and understand why, such as it being extremely hypotonic for instance.
I looked into it a short while ago, for the reason of the strength of this stuff that we splash around and could it do damage to the seals etc. It was educational, but alot of information to take in as regards to my reason why. Concluded that guys have been doing for a while and no legal cases or causes been brought forward.
On those points I would assume that total parts per billion have a faster, more aggressive dissolvent rate than that of parts per million. However does that translate to an increased clean time per window for the actual length of time we spend per window. I wouldnt have thought so, to the extreme thats mention on this thread. But then I dont use ppm and so could be completely wrong and be interested to see it at work
The thing is Nathan its only going to be somebodies opinion, some think hot cleans better others don't, some think adding a
small amount of a cleaning solution to your water improves it others don't.
I see the exact same as NWH when I change my resin it seems to clean better and quicker but I honestly couldn't tell if its
down to me looking more closely at the clean and seeing things that I wouldn't be looking for if the resin was older.
The mistake your making is thinking that we clean the dirt of the glass by dissolving it in water, that's not the case we loosen the
dirt and use the water to rinse/push it off the glass dissolving it has very little to do with the process.
Fill a bucket with pure throw in a pile of dirt stir it and let it sit, you will find that most of it will sink to the bottom and never
get dissolved, it will only be certain things within that dirt such as salts that will become dissolved solids and raise the tds.
