You can also test your tap water using a little dish soap. Fill a bottle with water, add a few drops of soap, close it, and shake well. If the water becomes full of fluffy bubbles and stays relatively clear, it’s an indication of soft water. However, if you see only a thin layer of bubbles and the water looks cloudy or filmy, your water is likely hard. This is a quick and easy experiment that shows how minerals affect water’s reaction with soap. The result not only reflects water quality for drinking but also highlights why hard water often makes washing clothes or dishes more difficult.
👉 Remember, this is just a home-based check. For a complete and trustworthy analysis of your water, getting it tested by professionals is always recommended.
