Spotless Windows Every Time: A Complete Guide to Producing Pure Water for Window Cleaning with Reverse Osmosis
Clean windows are essential to maintaining the appearance of any building, whether it’s a residential or commercial property. However, cleaning windows with ordinary tap water can result in spotting and streaking, making the windows look worse than before. To achieve spotless windows, it’s important to use pure water for cleaning.
So, how do you make pure water for window cleaning? The answer lies in reverse osmosis systems. Reverse osmosis is a process of purifying water by removing impurities and dissolved solids through a semi-permeable membrane. To make pure water for window cleaning, you need to pump hard water through a reverse osmosis system and then test the water to make sure the TDS (total dissolved solids) reading is below 0.07.

What is a Reverse osmosis?
Reverse osmosis (RO) is a water purification process that uses a semi-permeable membrane to remove impurities from water. In simple terms, reverse osmosis works by applying pressure to push water through a membrane that allows only water molecules to pass through, while blocking other contaminants. This process can remove up to 99% of dissolved salts, minerals, and other impurities from water, making it ideal for various applications, such as drinking water, industrial processes, and window cleaning.
The process of reverse osmosis involves several stages. First, the water is passed through a pre-filter to remove larger particles and debris. Then, it goes through the semi-permeable membrane, where impurities are removed. The water that passes through the membrane is known as permeate, while the impurities that are rejected by the membrane are known as concentrate or reject water. The concentrate is usually discharged to a drain or sent back to the source for further treatment.
The purity of the water used for window cleaning is crucial. If not done correctly, the windows will have spots and streaks, defeating the purpose of cleaning them. The first step in making pure water is to check how hard your water is by using a TDS meter. If your water is under 100 ppm, you may be able to use a DI (deionization) vessel alone. However, in the long run, it may be more cost-effective to invest in a reverse osmosis system.
When buying a reverse osmosis system, it’s essential to consider the GPD (gallons per day) rating. The higher the GPD rating, the more water the system can produce, but the more expensive it is. The 400GPD reverse osmosis with a DI chamber is a popular choice among window cleaners. It comes pre-filled with resin and is ready to use out of the box.
Before connecting your water to the filters, make sure that your water pressure is sufficient. If your pressure is low, you can purchase a booster pump to speed up the process. Once connected, you will have two pipes coming out of the system – one for waste water and the other for pure water. The waste water should be drained into a suitable area.
If you live in an area with soft water, you may be able to get away with using a DI vessel alone. However, if your water is under 100ppm and the DI vessel takes it down to 5 or over, you will need to purchase a second vessel.
Using pure water for window cleaning has many advantages. Firstly, it ensures spotless results by removing all minerals and irons during the filtering process. Secondly, windows stay cleaner for longer when cleaned with pure water as it deters dirt, unlike dish soap which can attract dirt. Lastly, pure water is safe for the customer’s property as no detergents are used.
In conclusion, producing pure water for window cleaning is an essential part of the process that requires careful consideration and planning. By using a reverse osmosis system, you can effectively remove impurities from hard water and ensure that your window cleaning results are spotless and streak-free. However, it is important to determine the hardness of your water before investing in a reverse osmosis system and to choose the appropriate GPD for your needs.
Using pure water for window cleaning not only delivers superior results but is also environmentally friendly, safe for customers’ property, and extends the life of window cleaning equipment. By following the tips and recommendations provided in this article, you can produce pure water for window cleaning with ease and achieve professional-level cleaning results.
