At this point there’s no question about it, we clean windows and clean them well. If you think that window cleaning methods have only advanced as far as paper towel and a bottle of Windex, you’re wrong (no offense).
Window cleaning is just like any other service trade, many have tried and many have failed. Leaving streaks behind is something that we simply do not do. There’s a lot more behind proper window cleaning than you may think – ready for some science!?
Okay, so when there are molecules in the water that you use to clean windows; there will be streaks left behind. Simple as that. That probably leaves you with a few questions now. What are these molecules, and more importantly how do I get them out of my precious water?
TDS: a measure of the combined content of all inorganic and organic substances contained in a liquid in molecular, ionized or micro-granular (colloidal sol) suspended form.
The molecules found in water typically come from common organic sources such as leaves, silt, waste and sewage. These molecules are charged both negatively and positively. Elite uses an amazing piece of equipment that purifies our water through first a carbon filter, then at RO filter (revers Osmosis) followed by a DI (deionization) filtration system. This removes any TDS (total dissolved solids) from the water through an ion exchange leaving you with 100% pure partial free water to use on your windows.
Next, of course, there must be a way to check if there is a low TDS in your water. That is what we use a TDS meter for. With a TDS meter we are able to test the TDS levels in the water before it is used on any ways. This is just another way of assuring there are no streaks or imperfections left on the windows once the job is done. A TDS over 50 will more than likely leave streaks on windows.
Everyday we are finding new and innovative ways to clean windows cleaner, safer, and better.
