Hard water contains a lot of minerals such as iron and potassium. Some geographical areas are known for naturally having hard water. Hard water can leave a white flaky mineral residue behind when it dries. This can make surfaces such as your swimming pool look dirty. Do not let hard water stains build up, as they can eventually etch your pool surface.
Things You'll Need
- White vinegar
- Spray bottle
- Pool brush
Drain the pool if the hard water stains are under the water. If they are simply on the pool deck or above the water line, do not drain the water.
Pour distilled white vinegar into a spray bottle. White vinegar is an acid cleaner that will remove alkaline stains such as hard water.
Spray the white vinegar on the hard water stains on the swimming pool. Don't spray the white vinegar in the pool water, as this could disturb your pool's pH balance and give the pool an unpleasant odor. If the hard water stains are close to the waterline, spray the vinegar on a clean cloth and hold it over the hard water stain.
Let the white vinegar sit on the hard water stain for several minutes.
Scrub the hard water stain with your pool brush until you've removed them.
