The importance of getting accurate TDS readings

Been a very busy week this week, with the weather picking up always sees me rushed off my feet with work. I realised Id fail to write about the importance of making regular TDS readings from your setup to ensure the water your cleaning the windows with is pure, or as close to pure as possible. Generally TDS readings of between 0 and 20 ppm is okay. Higher readings and you might find the water is not doing a very good job of removing the dirt off the windows. If you don't have a TDS meter, you can easily purchase them from any window cleaning equipment supplier. Or you can fit an inline TDS meter for getting readings from the RO when you want.
