Water softener salt is a form of sodium chloride, or table salt. It is typically used in water softeners to remove minerals from hard water that cause soap scum and scale buildup.

Water softener salt can be used in a variety of ways around the home. It is an effective de-icer when sprinkled on icy sidewalks and driveways. It also helps prevent ice from forming and makes it easier to shovel snow away. Additionally, water softener salt can be used as a fertilizer for plants, as it increases the soil’s fertility and helps prevent diseases. When added to the water in swimming pools, it can help keep algae at bay. Water softener salt is also effective in removing grease stains from carpeting and fabrics.

No, they are not. Rock salt is simply large chunks of sodium chloride that has been mined from the earth. Rock salt is sometimes used as a deicing agent on roads and sidewalks in cold climates. Water softener salt, on the other hand, is usually crystals of evaporated sea water or mined deposits that have been specifically processed for use in water softeners. While both kinds of salt are composed mostly of sodium chloride, water softener salt contains fewer impurities and has a more consistent shape, making it better for use in water softening systems. Furthermore, rock salt is usually not suitable for water softening because it releases too many insoluble materials into the system that can clog it up. Therefore, when purchasing salt for use in a water softener, it is essential to use a specially-processed water softener salt.

Uses Of Water Softener Salt

  • For melting ice: Water softener salt is made up of large grains, which makes it ideal for melting ice. Sprinkle some of the salt on icy surfaces and driveways to melt ice quickly.
  • For killing weeds: A solution made of water softened salt can help kill weeds without the use of harmful chemicals. Simply mix one part water softener salt with five parts water, pour it onto unwanted plants or weeds growing in your garden or lawn, and watch the weeds die.
  • For removing rust stains: Water softener salt can be used as an effective rust remover if mixed with lemon juice. Create a paste from these two ingredients, apply to affected area, let sit for 10-15 minutes, and then rinse away with cold water. You should see a significant improvement in the appearance of the stain.
  • use water softener salt on your driveway: Water softener salt is not only useful for removing hard water deposits from your home’s plumbing system. It can also be used to help maintain the surface of your driveway! Sprinkle a small amount on areas with snow or ice, and use a shovel or broom to spread it around. The salt will help melt away the snow and ice, making it easier to drive over. Make sure to sweep up any excess salt when you’re done so that it doesn’t get washed into the ground. You can also use salt periodically throughout the winter months to help keep icy patches at bay.
  • Use on the walkway: You can sprinkle some water softener salt on the walkway and it will reduce ice buildup during the winter months. It helps to prevent slipping by creating a surface that isn’t as slippery as regular ice.
  • Use water softener salt to kill grass and weeds: Water softener salt can be used as an effective way to control weeds in your lawn and garden. By sprinkling the salt around the area you want to kill, it will draw moisture away from the roots of the plants, which will slowly dehydrate them and eventually cause them to die. However, it’s important to note that using too much of this salt can also damage your soil.
  • Protect Your Vegetables From Slugs: Water softener salt can be used to create an effective barrier around your garden or outdoor plants to help protect them from slugs. Spread the salt in a thick layer around the perimeter of your planting beds, and the salt will dehydrate any slugs that venture onto it. Reapply after rain or when you notice gaps in the coverage.
  • Use for rust removal: Using water softener salt, put the items in a container and cover them with warm water. Let sit for 10 to 15 minutes and then scrub away the rust easily with an abrasive sponge or brush. You can also use dry salt on rusty tools that cannot be submerged in water. Simply sprinkle the salt onto the rusted area, add some lemon juice or white vinegar, let it sit for a while, and then scrub it off.
  • It will stop candles from dripping: Water softener salt can be used to stop candles from dripping. Simply sprinkle some of the salt into the wax before burning, and it will solidify and prevent the liquid wax from spilling out.

Solar Salt Vs Rock Salt

Water softener salt is available in two forms: solar salt and rock salt. Solar salt, also known as evaporated salt, is made of small pellets or cubes of compacted sodium chloride that have been harvested from sea water. Rock salt is produced by mining underground deposits of halite (salt). It usually contains trace minerals such as magnesium and calcium, which can give it a slightly different taste than solar salt.

In addition to being used in water softeners, both varieties of water softener salt can be used for other purposes. For example, rock salt can be applied directly to icy sidewalks and roads during winter months due to its ability to lower the freezing temperature of water. Solar salt is often added directly to swimming pools to raise their chlorine levels, making it very popular among pool owners. Solar salt can also be used in the production of soaps and detergents.

Yes, you can use water softener salt in your pool, though it is not the most cost-effective option. Water softener salt functions similarly to regular pool salt and helps keep the pH of your pool balanced. When using water softener salt for a swimming pool, it is important to note that the grains are larger than those found in regular pool salt and may leave a gritty feel on your skin. Additionally, it is important to use high-quality water softener salt that has been tested for purity as impurities can lead to scaling or corrosion of metal surfaces in the pool. Lastly, you will need to use significantly more water softener salt than regular table salt due to the larger grain size. All of this can make it a more expensive option than regular pool salt, but if you already have water softener salt on hand then it can be used in your pool.

Yes, it can! By adding a teaspoon of salt to the detergent compartment, you can help reduce water spots and reduce the build-up of hard minerals in your dishwasher. Water softener salt can also be used as an abrasive cleaner for pots and pans – simply mix it with hot water and use a sponge or scrub brush to clean stubbornly stuck-on residue. What’s more, this combination makes an effective wallpaper or grout cleaner as well.


Are there different types of water softener salt?

Yes. The two main types are rock salt and solar salt, which both contain sodium chloride as the active ingredient. Rock salt is mined from ancient underground deposits, while solar salt is harvested from evaporated seawater. Depending on your needs and budget, either type may be suitable for use in a water softener system.

Does the salt go bad?

No, the salt does not go bad. Water softener salt is a stable material that can last indefinitely if stored properly and in the right conditions. However, it is important to change the salt regularly – generally every 6 months – as it will become too saturated with magnesium and calcium minerals over time.

Is water softener salt edible?

No, water softener salt is not edible and should never be ingested. While the salt used in water softeners has been processed to remove any impurities, it is still considered a mineral-based product and can contain high levels of sodium chloride which can be dangerous if consumed.

You can determine the size of your tank by checking the manufacturer’s manual or consulting a professional.


In conclusion, water softener salt has a variety of uses. It can be used to soften hard water, as well as to de-ice driveways and sidewalks during the winter months. It can also be used to improve soil quality in gardens and lawns. Salt can even be used to create homemade cleaning products that are effective but much cheaper than store-bought products. With its variety of uses, water softener salt can be a great addition to any home or garden.
