How to Dechlorinate Tap Water for Free and at Home! [6 Ways]

If you have ever lost your water supply for a week or longer due to storm power outages, you appreciate the benefits of city water. But public water systems have a notable downside. The water sometimes tastes chlorinated. Sometimes heavily chlorinated!

Modern homesteaders appreciate the value of water that is both germ-free and chlorine-free. We enjoy clean water that’s safe to drink. But the chlorine taste is terrible! So we want to give you ways to dechlorinate tap water at home.

For free! (Or cheap.)

But first, let’s go over why you need dechlorinated water for some of your most basic (and fun) homesteading activities.

Sound good?

Then let’s begin!

Seven Reasons You Need Dechlorinated Water

Before we show you how to dechlorinate water, we have a big tip. Are you concerned about harmful chemicals, heavy metals, ammonia levels, or other chemical agents in your tap water? Then ask your water utility company for their latest consumer confidence report – or CCR! Your water utility provider or your water company must provide you with a consumer confidence report, per the US environmental protection agency (EPA.) Many governments from other Western countries follow similar guidelines. Familiarize yourself with local water policies. And make the water company uphold its obligation to serve healthy public waters!

There’s no doubt that modern rural and municipal water systems are a boon to good health. Chlorination eliminates some strains of bacteria and viruses that once were a significant source of disease and death that are essentially unknown today. However, some homesteading activities don’t work well when using chlorinated water.

Consider the following!

1. Baking Bread

Heavily chlorinated water is not ideal for yeast and homemade baked bread! Our favorite budget options for homemade baking are distilled water or bottled drinking water. Most baking recipes don’t call for much water – and the bottled water quality is usually superior to tap water for cooking.

Sometimes, chlorinated water gives the bread a chlorine taste. The bigger problem is that heavily chlorinated water can interfere with yeast growth. Your bread could take longer to rise. And it may not rise as high. You should never activate a sourdough starter in chlorinated water. (Chlorine kills the sourdough starter!)

2. Brewing Beer

Chlorine is helpful for beer making because it can help to sanitize your brewing equipment before use. However, the beer water is a different story. No chlorine for the beer water, please! One excellent home-brewing guide suggested that the boiling method works fine for eliminating chlorine from beer-making water. (Boiling is an effective method for brewing since you may need many gallons of water – or more. So using bottled water might not be the best choice.)

Chlorinated water interferes with the action of yeast in the wort. It can cause off flavors. In high concentrations, it can corrode or darken various metals or stainless steel.

3. Clothing Care

We’ve never experienced trouble with trace chlorine in our laundry. However, we read a fascinating report from the Texas Cooperative Extension that says alkaline builders and chlorine bleach can make stains worse!

High levels of chlorine can fade dark colors. They can weaken the thread of fabrics of any color. If the tap water causes brown laundry stains due to high manganese or iron, chlorine can worsen the stains.

4. Hair and Skin Care

The Indiana University Bloomington blog says that showering in chlorinated water may introduce more chlorine byproducts into your blood than drinking chlorinated water! For that reason – introducing a carbon filter or other water softener filter might increase your shower water quality.

Exposure to excessive chlorine can leave your hair dry and brittle. As well as make your skin itchy. We don’t think tap water has sufficient chlorine to cause dramatic hair damage. However, if your skin is sensitive, try using a filtered shower head when you shampoo and shower. It might make a big difference in how you look and feel.

5. Hydroponics

Most municipal water systems won’t contain adequate chlorine to kill plants. However, we read that certain plants, like peace lilies, are tremendously sensitive to chemicals. We also read from the PennState blog that some plants may get impacted by chlorinated water if it’s sufficiently chlorinated. Other reliable sources say that letting the tap water breathe for 24 hours in an open container will help drastically reduce chlorine levels, so it’s suitable for aquaponic applications.

Chlorine can interfere with the ability of hydroponic irrigation systems to deliver the trace minerals plants need just before they flower and set fruit. In an enclosed hydroponic system, there is no way for chlorine to escape just by shutting the system down for a few hours. Chlorine can also get absorbed by plants. (If your plants react negatively to chlorinated tap water, try distilled water.)

6. Keeping Chickens, Fish, and Other Pets

Even though your fish tank likely has a special filter, we advise against using regular water or tap water for your tank. We’ve read from several trustworthy sources that tap water with chlorine can harm your fish – even in small amounts. Higher amounts can potentially kill your fish. Make sure your water is bottled water quality. And always sample aquarium water with a reliable testing kit!

The digestive tracts of chickens and their manures can contain Salmonella bacteria. These bacteria can build a resistance to chlorine. Then decontaminating against Salmonella becomes more difficult.

Excessive chlorine can damage the gills of fish you keep in an aquarium or an outdoor pond. Even when you can’t smell chlorine, it may be present in concentrations that are toxic to fish.

Signs of excessive chlorine are similar to low oxygen levels. Look for fish floating to the surface and fanning the gills as if desperately trying to breathe.

Dogs that swim in chlorinated water may develop dull coats and dry, itchy skin.

Chloramines in drinking water are highly toxic to snakesturtleslizards, and amphibians.

7. Making Coffee and Tea

We recently read an excellent article teaching how to brew perfect coffee. The article reminds us that water makes up 98.7% of your morning coffee cup! The guide recommends skipping chlorinated water and opting for bottled or filtered water. We agree. Chlorinated water has its place. But never for fresh homemade coffee!

Many people don’t like the taste of coffee and tea made with chlorinated water.

You can solve any problem with excessive chlorination by installing a reverse osmosis system for your home and garden.

There is, however, a significant downside to using modern technology to get rid of chlorine. It’s the cost!

A whole-house reverse osmosis system will cost at least $150. A reverse osmosis system big enough for a small (two-acre or one-hectare) farm will probably cost around $7,500.

Fortunately, it is possible to get rid of chlorine from tap water for free. Or for cheap.

Here are some of our favorite methods.

6 Ways to Dechlorinate Tap Water for Free – or for Cheap!

Let’s start with the simplest zero-cost foolproof method of removing chlorine in tap water.

1. Let Tap Water Stand Uncovered Over Night

When researching how to dechlorinate water for free, we stumbled upon a chlorine disinfectant guide on the Tampa.gov website. Their water chlorination FAQ section says that chlorinated water is safe to drink. They also write how letting a pitcher of water sit idly for a few hours can help drastically reduce the chlorine flavor. You can pour a pitcher, sit back, and then let the chlorine evaporate.

Here’s the easiest way to remove the chlorine flavor from water. Pour it from your faucet. Then wait a while!

We’ve read from multiple reliable sources that letting tap water sit in an open container for a day helps reduce the chlorine flavor dramatically. You can fill a pitcher of water in your fridge, for example.

 (Make sure you let the water stand in an open container. The more air-to-surface area exposure the water gets, the better.)

2. Boil Water for 15 Minutes

We read another helpful report from Alaska’s Drinking Water Program. They provide many practical tips for helping reduce the chlorine flavor in tap water. Our favorite chlorinated water tip is to boil the water for ten to fifteen minutes. You can toss the water pitcher in the fridge after it cools and use it whenever you wish.

Bringing tap water to a rolling boil for 15 minutes kills that nasty chlorine flavor. For sure! Even though chlorine is heavier than room-temperature air, it’s lighter than steam, so the bubbles of boiling water will carry it away. Boiled water, of course, tastes flat. But your plants and your pets won’t care.

(Let the dechlorinated boiled water return to room temperature before using.)

3. Adding Vitamin C

Vitamin C is a new(ish) method of neutralizing chlorine. We’re new to the process. However, we’re proponents because it reduces chlorine without requiring UV exposure, direct sunlight, or bottled spring water. And it seems like a cheap method! We’ve read that sodium ascorbate or ascorbic acid vitamin C will help remove chlorine.

Vitamin C is likely the safest of all the chemicals used to remove chlorine from tap water. One of our favorite vitamin C dechlorination insights was on the University of Nebraska (Lincoln) Extension website. They say that adding 50 mg of ascorbic acid per liter of water improves the taste in chemically-treated water.

You can find ascorbic acid tablets for dechlorinating small amounts of tap water. And vitamin C balls to put in your shower head to dechlorinate tap water for shampooing your hair. 

There is an additional consideration for using vitamin C to dechlorinate water for pet care. Vitamin C (1) removes free oxygen in tap water. And (2) lowers its pH. You should consider these two effects when using vitamin C to dechlorinate tap water for pet fish.

Aeration will compensate for the free oxygen removed by vitamin C. Making sure you use sodium ascorbate instead of other forms of vitamin C should impact pH minimally.

4. UV Treatment (or Sunlight!)

We’ve read that direct sunlight might be an excellent method to dechlorinate water. However, we’ve only found one study investigating the efficacy of ultraviolet light in removing chlorine. Fascinatingly, and coincidentally, we’ve also read from multiple reliable sources that a UV light source might fight a broader spectrum of organisms than chlorine. Some even say UV light is better than chlorine for water treatment outright. Who knew?

Sunlight can help expedite your chlorination-ridding process. UV light accelerates how fast calcium hypochlorite and sodium hypochlorite break down into chlorine gas.

UV light exposure is a surprisingly easy method for eliminating the chlorine in municipal water that you use for maintaining an outdoor fish pond. Just add a waterfall effect. Sunlight will break down chlorine, and recirculating water through the waterfall will help liberate the chlorine gas into the air.

5. Under-the-Sink Charcoal Filtration Units

Reverse osmosis water filters are our favorite way to remove chlorine from the water and make tap water safe! Not only do osmosis filters remove ions, metals, chlorines, and radon, but also other nasty stuff you don’t want in your water. (We read how reverse osmosis systems also remove pesticides and organic chemicals. Good riddance!)

If you have $50 to spare, there is an easy way to dechlorinate kitchen tap water for everyday use. Just install a charcoal filter unit under your sink.

Charcoal filters aren’t as effective as reverse osmosis filtration units. But they aren’t as hard to maintain. Charcoal filters will also remove odor-causing organic matter and some mineral contaminants.

(If you drink a ton of water, consider adding a reverse osmosis filter. Forbes lists the cost as low as $150 but upwards of $15,000. For small-scale residential use, the price is on the lower end of that range. It might be well worth the investment if you drink lots of water. Or if you detest chlorine flavor!)

6. Adding Lemon Juice to Dechlorinate Tap Water

Sick of the yucky chlorine taste? Try adding a slice of lemon! Not only will a few lemon slices add fresh flavor to tap water, but the ascorbic acid within also neutralizes the chlorine in tap water. Sounds good to us!

Here’s one of the most underrated methods to dechlorinate water. Just add lemons! Any acidic organic substance will work. Consider lemon juice or lime juice. Either can remove chlorine from tap water. It has to get mixed well, and the mixture should stand for a couple of hours. A tablespoon (15 ml) of lemon juice will dechlorinate a gallon (4 liters) of water for kitchen use. 

How to Dechlorinate Tap Water for Free – FAQs

We know water dechlorination is tricky. So we put together these tips for helping eradicate chlorine from water. We also share a few aquatic life tips. We hope they help!

Is Chlorine Safe for Aquarium Water?

No! Never use chlorine-treated water with your fish tank! Chlorine is dangerous for your fish. But you can treat the water so that it’s safe. One popular method of using chlorinated water for fish tanks is sodium thiosulfate. Sodium thiosulfate helps to remove chlorine from water, making it safe for an aquarium with water and fish.

No matter the source of dechlorination, we always recommend using an aquarium water testing kit to ensure the water is safe.

Is It Safe to Drink Chrolinated Water?

Yes! Drinking chlorinated water is considered a safe and viable practice. But we realize many homesteaders don’t like the taste. If it makes you feel better, the EPA (Environmental Protection Agency) limits how much chlorine your local water company may use.

Even still, we realize chlorine isn’t a natural method of removing parasites or bacteria, and many prefer a biological filter rather than a chemical treatment. However, we feel comforted to know some safeguards are in place.

Can You Put Fish Straight Into Tap Water? Or Add Tap Water to My Tank?

No! Even if you have a 1,000-gallon tank, we recommend against it. Tap water should get dechlorinated before it’s added to the fish tank. Some fish hobbyists say that tap water may be safe if their tank has an aeration device. But we disagree. We say it’s always better to remove the chlorine first! (Keep your fish safe! One slight water quality mistake can cause your fish to get sick. Or worse.)
