Difference Between Hard Water and Soft Water

The major difference between hard water and soft water is the presence of minerals. Hard water is good for drinking due to its rich mineral content. However, when compared to washing clothes or laundry, it is not a good choice

. The hard water leaves stains over the fabric and does not clean it. As it is rich in minerals, it does not clean out the detergent efficiently and leaves a bad odour with stains.

How water Becomes Hard?

The very common question appears in mind that how the water becomes hard or rich in minerals? The answer is simply that when the water passes through the deposits of limestone, it absorbs all minerals. Also, when it passes through the land, containing chalk or gypsum, it becomes rich with minerals.

These minerals include calcium carbonate, magnesium carbonate, sulfates, and bicarbonates. These minerals are very good for human health and prevent gastric cancer and other diseases.

However, if talking about laundry, it does not work well.

Now coming to the point that how the hard water affects laundry? It contains minerals and therefore it does not work well with any type of normal detergent. It does not clean the cloth or fabric efficiently instead leaves the minerals over it.

How do you Wash Your Clothes with Hard Water?

Some companies make special boosters or detergent liquids which deal with the hard water efficiently. The use of these products prevents any stain over the clothes and washes the fabric with scented agents.
