Can Water Be Too Soft? The Real Answer Explained

Can water be too soft? It’s a question that comes up a lot after people install a water softener and notice that shower water feels… different.

The honest answer is no — at least not in any way that’s harmful to you. Soft water feels slippery and unfamiliar at first, but that’s actually your skin without mineral residue on it. Your body isn’t used to feeling that clean.

Water softeners do a fantastic job, but the change can be jarring when you’ve spent years washing in hard water. Let’s clear up what’s really going on.

How to Identify Hard Water

To identify hard water, see if there’s a layer of residue on your skin every time you wash your hands with soap. That’s a telltale sign of hard water.

On the other hand, soft water can give you the sticky feeling you’re not used to. At first, it might even feel a little uncomfortable.

Instead, you might think that the water feels too viscous and soft. That doesn’t mean you should avoid it.

Installing a water softener can save you a lot of money on expensive lotions. If you’re not sure whether the investment makes sense, read our guide on whether a water softener is worth it.

With less money, you can enjoy skin as smooth as natural silk.

How to Tell If Your Water Is Too Soft

Here are some guidelines on how to tell if your water is too soft.

Taste It

It’s the minerals in the water that give it its characteristic taste, and incredibly soft water contains few minerals. Essentially it’s distilled water.

It will have the smooth taste of distilled water and will probably be unpleasant to drink.

Test It

There are test kits available to measure the different minerals in your water. If the kits indicate low mineral levels, your water may be too soft.

If the salt content is high, it may be coming from your water softener. Softeners use chloride to remove minerals from the water, and a high salt content means too many minerals may have been removed. Learning how much salt to use in your water softener can help prevent this issue.

Check Your Faucets

One of the disadvantages of having minerals in water is that over time they begin to leave deposits on your faucets. Water with standard mineral content will also cause this problem.

If you’ve been using the same water source for years and your taps are free of deposits and stains, you can be confident the water is very soft. With soft water, appliances that use water last 30% longer. For more on equipment longevity, see our guide on how long a water softener lasts.

Soap

Minerals in water can interfere with soap suds and other cleaning products. If your soap suds are excessive or the soap is too slippery, the water may be very soft.

This is disadvantageous because it can increase the cost of cleaning products if you use too much. But in practice, you simply need less soap to get the same results.

My Water Is Too Soft, Can I Make It Harder?

From time to time, people ask if there’s a way to make the water less soft when the softener is installed. Yes, that’s the simple answer, but before you go down that road, here are a few things to think about.

Use less soap when showering or bathing, about one-third of what you usually use. Sometimes people say they can’t get the soap out.

The fact is that what you’re used to when you shower in hard water is soap and chalk residue.

Now that you often experience what people call “gooey,” the more accurate word would be “silky.” Soft water won’t create soap scum or contain chalk, leaving the skin and pores clean and free of the dirt that contributes significantly to skin disorders such as eczema and psoriasis. You can also try putting vinegar in your water softener to keep the system clean and working at its best.

Why Is Soft Water Slippery?

If you’ve been using hard water in your home all your life, the immediate benefits of switching to soft water are apparent. Using less detergent reduces wear and tear on water appliances and maintains efficient plumbing in your home.

Another component of soft water, often overlooked, appears at your first bath or shower. It’s entirely different from hard water.

Soft water creates a different feeling on your skin, often described as “slippery” or “silky” compared to hard water. This often leads those who aren’t used to soft water to suspect that their water softener has a problem.

What Makes Soft Water Feel Slippery?

The science behind this silky-smooth feeling starts with the types of minerals (or lack thereof) in the water you bathe with.

Hard water contains dissolved calcium and magnesium, which naturally accumulate as the water flows over rock below ground. These minerals work their way through the plumbing and showerhead, leaving a flaky white residue as the water dries.

The minerals make it very difficult to cleanse the skin properly. The hardness ions react with detergents in soap and coagulating shampoos, leaving the detection rings around the bathtub.

This hardness-soap combination is also difficult to rinse off the skin properly.

The soap foam becomes granular, which can make cleaning more difficult. The excess residue left on the skin clogs the pores and excessively dries out the skin.

Your skin doesn’t dry out when you take a bath or shower in soft water because it allows soaps and shampoos to rinse your skin and hair thoroughly. You’ll also use far fewer cleaning products to create a lather.

If you’re used to bathing in hard water and have only recently installed a softener, the usual amount of soap you used may be too much now. Too much soap makes soft water feel not only oily but also smoother.

Since hard minerals are small pieces of rock, there would be less friction when rubbing your fingers together under a stream of water without these abrasive materials.

Benefits of Soft Water

Economic and Energy Benefits

One of the fundamental differences between hard and soft water is the impact on your home. Hard water leaves behind deposits of minerals such as chalk and lime when it flows through pipes.

Over time, this causes a buildup of limescale that reduces the flow of water and can cause piping problems, such as corrosion. With hard water, calcium deposits can build up in your kettle and around your sink.

The same thing happens in your water heater, and over time this reduces heat transfer, requiring more energy to heat the water. The buildup of minerals can also increase the pressure on washing machines and showerheads.

One of the significant advantages of soft water is that it has none of these disadvantages. When a soft water system is installed, households can save on equipment repair costs, maintenance, and energy bills.

Hair and Skin Benefits

The benefits of soft water extend to your hair and skin. Soft water allows the foam to rinse out, while hard water leaves a dandruff-like residue.

With hard water, the soap film will show up on your taps, bathtub, and bathroom. After showering, you may feel your skin squeak clean instead of smooth and soft.

Hard water doesn’t activate soap suds as effectively as soft water, leaving a small amount of soap residue on the skin that can block pores and cause acne. The minerals in hard water can also remove natural oils from the skin, causing itching and dry skin problems.

Hair can also become dry and brittle due to hard water for the same reasons. Washing with soft water means there are no soap or mineral residues on the face, scalp, or hair, so the natural skin oils will do their job.

Health Benefits of Soft Water

The use of soft water extends from cleaning the kitchen, bathroom, and clothing to skin and hair care. The health benefits of soft water aren’t as noticeable with your internal health.

The water you choose to drink depends mostly on your family’s needs and preferences and the type of water itself. Chemically softened water is generally safe to drink.

Still, if you need to limit sodium intake, it may not be the best type because it replaces calcium and magnesium with sodium.

Salt in soft water, however, adds less than 3% of the daily sodium intake, so there’s generally no danger of overdoing it.

On the other hand, there’s evidence that softened water can remove lead and cadmium from pipes, which can affect safety. But while water consumption is almost always safe, softened water doesn’t have distinct health benefits because it may not provide the essential minerals that are important to our health.

Calcium, magnesium, potassium, and sodium, as well as various other minerals found in water, are an integral part of our diet. Still, many of us don’t get enough of them.

This is where the advantage of natural mineral water over soft or distilled water lies.

Is it possible to have soft water that doesn’t overload the body with mineral salts and is also safe for everyone? That also contains many of these abundant mineral ions to promote health?

This is an ongoing question in the water treatment industry.

Soft Water Bathing Tips

Here are some bathing tips when using soft water.

Use Pure Soaps

Soap works by attracting oils and greasing them into small balls, making it easy to wash them off surfaces. Some soaps contain ingredients such as perfumes or stable dyes.

Some also contain softening agents, assuming the user washes with hard water.

Since soft water dramatically increases the effectiveness of your soaps, you don’t need these additives. Look for transparent liquid soaps with essential ingredients and no strong fragrances or colors.

Use Less Soap

You don’t need as much soap to get a good lather in soft water. A little goes a long way.

Let the water do its job and save time and money by extending the life of your soap bottle.

Enjoy the Benefits

You’ll notice the changes in your skin and hair over time after bathing in soft water. Your skin will feel moisturized and healthy.

The lack of hardness minerals will allow your hair to clean itself more efficiently without the feeling of brittleness.

Hard Truths About Soft Water

If you’ve ever turned to the internet for information on hard water or water softening systems, you’ve probably noticed conflicting information.

Some websites support soft water and softeners, usually because they sell them, while others denounce soft water as harmful. Any intelligent user can see that most of the “truths about soft water” are heavily distorted.

A common misconception is that ion exchange isn’t the only way to soften water. Water softening is only possible by exchanging sodium ions with calcium and magnesium ions. If you’re curious about how this process works, our article on how often a water softener regenerates explains the ion exchange cycle in detail.

Other systems aim to soften water without salt, but these are water conditioners, not water softeners. We cover these in our guide to water softener alternatives.

These devices don’t extract minerals from the water but capture and shape them into insoluble crystalline particles that can’t conform to the pipes or appliances. They can’t form the scale deposits that are the characteristic symptom of hard water.

New technologies are on the horizon, such as capacitive deionization, but they also have drawbacks. A water softener is still the best approach for actually softening water. Check out our picks for the best water softener salt to keep your system running smoothly.

Why Cooking With Soft Water Is Better

Cooking isn’t always an easy task. The list of ingredients can sometimes be a mile long, and one element that’s always ignored is water.

You may think that water has no taste, but it can affect your cooking. With soft water, you can guarantee a pure and smooth taste.

Taste Is Improved

Cooking with soft water will help give your food a mineral-free taste. Pure, soft water also helps to preserve the authentic taste of the ingredients.

When cooking any form of pasta, for example, water that’s too hard results in a firmer dough. Water that’s too soft makes the dough weaker.

Water purified by a water softener will help your dish behave as intended.

Vegetables Are Better

Another advantage of soft water is that it makes it easier to cook vegetables. We know that vegetables can be challenging to eat, but sometimes cooking them adds flavor.

Use soft water to make sure your vegetables have the best texture and vitamin content. Hard water delays the cooking process of vegetables because it makes them harder.

The extra time it takes to cook vegetables will leave them overcooked and bland. It’s faster to cook vegetables in soft water while giving them a better taste and texture.

Drinks Are Tastier

Drinks such as tea and coffee taste much better due to the reduced limescale content of the soft water. This also affects the cooking of sauces, broths, and gravies.

Soft water accepts flavors more quickly than hard water.

A good example is the preparation of iced tea with hard water. When it cools, it becomes cloudy.

By installing a reverse osmosis filtration system, all minerals and other impurities are removed from the water entering the house. Many homeowners appreciate the pure, all-natural water produced by water softeners. You may also want to learn whether a water softener removes chlorine, since chlorine affects both taste and cooking results.

Soft Water and Gardening

Most of the time, watering the garden with softened water isn’t a good idea. This is because softened water usually contains a high volume of sodium derived from salt. Knowing what your water softener hardness should be set at can help minimize sodium levels in your softened water.

Most plants can’t tolerate high concentrations of salt.

In soft water, sodium interferes with the water balance of plants and can kill them by “fooling” them into thinking they have absorbed more water than they have. The softened water eventually causes the plants to die of thirst.

The salt in soft water affects not just the plants you water but also the soil, making it impossible for future plants to grow.

Soft Water Homes and Watering

This doesn’t mean you can’t water the garden if the water has been softened. If the water in your home is softened, there are a few options.

You should have a bypass valve installed. This means you can have a special tap outside your home that takes water from the water line before it’s treated in the softener.

You can also try mixing the softened water with collected or distilled rainwater. This will dilute the salt’s effects, making it less harmful to your plants.

But salt will always accumulate in softened-soil water. It’s essential to check the soil to make sure the salt level remains manageable.

How to Treat Soil Affected by Softened Water

You’ll need to work to correct the salt levels in the soil if the land is too saturated with softened water. There are no mechanical methods to reduce the amount of salt in your soil, but you can do this manually by regularly watering the earth with unsoftened water.

This is called leaching. Leaching extracts salt from the soil and pushes it deeper or carries it away.

While leaching removes salt from contaminated soil, it also removes the nutrients and minerals your plants need to grow. This means that you need to make sure you return these nutrients and minerals to the soil.

Washing

Soft water isn’t as abrasive as hard water, making it ideal for washing clothes to avoid damage. However, soft water will have difficulty removing soap from your skin and hair shampoo, which means you’ll use more water when you shower.

Aquariums

Soft water can’t be used safely in aquariums. Fish need stringent pH levels to preserve their ecosystem, but soft water is very sensitive to pH fluctuations. If you keep fish, you might want to look into aquarium water softeners designed especially for this purpose.

These fluctuations can occur even with the smallest additives such as fish waste. These pH changes could potentially damage or kill fish.
