If you notice that your faucets have a chalky white buildup, there are spots on your dishes, or your clothes feel rough and stiff, your home may have hard water. Hard water usually contains a high concentration of minerals like calcium or magnesium, which can dry out your skin and hair, decrease the life of your appliances, and cause a funny taste or smell. The best way to soften your water is to install an ion exchange softener in your home, but we’ll also go over DIY methods to decrease the effects of hard water naturally. Keep reading to learn more!
Best Ways to Soften Hard Water Naturally
Boil your water to remove calcium carbonate.
Sprinkle baking soda in your water before you cook or bathe.
Rinse with diluted apple cider vinegar after showering or bathing.
Install an ion exchange shower head filter to remove minerals.
Add washing soda to your laundry to eliminate calcium and magnesium.
Descale your faucets and appliances with diluted vinegar.
Steps
1
Boil away impurities.
Download Article
Boiling removes calcium carbonate from hard water. Fill a clean pot or kettle with water and place it on a stove burner set to high. Allow the water to boil for a few minutes, then turn off the heat.[1]XResearch source Let the water cool, then use a spoon to scoop the sediment off the top of the water before transferring it to a clean container.
The sediment will most likely be white and chalky. That’s the calcium leaving the water.[2]XResearch source
Boiling doesn’t get rid of all the impurities in hard water, just temporary hardness caused by calcium, magnesium, and other minerals.[3]X Trustworthy Source PubMed CentralJournal archive from the U.S. National Institutes of Health Go to source
Boiling tap water before drinking it may also help reduce your consumption of microplastics because they bond with the calcium carbonate.[4]X Trustworthy Source American Chemical SocietyScientific society for those involved with chemistry and publisher of several leading peer-reviewed scientific journals Go to source

Use baking soda in your cooking water.
Download Article
Some foods become tough and rubbery when cooked in hard water. While baking soda can’t soften water completely, it will help alter the pH level to a more natural state.[5]XResearch source Fill up a pot of water and add 1 tsp (5.6 g) of baking soda when you’re cooking dried beans and peas for a better taste and texture.[6]XResearch source
Soft water also enhances the flavors and aromas in your cooking.
Bathe in baking soda water to reduce itching caused by hard water. Sprinkle 1/4 cup (32 g) of baking soda into your bath, then soak in it.[7]X Trustworthy Source National Eczema AssociationNonprofit organization dedicated to improving the lives of those with eczema through research and education Go to source When you’re done, wash with soap to get rid of any residue.
3
Rinse your body with apple cider vinegar.
Download Article
Apple cider vinegar removes mineral buildup on your skin and hair. Apple cider vinegar (ACV) may balance your skin’s pH levels.[8]XResearch source It also contains chelating agents that bond to and remove excess minerals.[9]XResearch source Add 1⁄2 US tbsp (7.4 mL) of ACV to 1 cup (8 oz) of water and pour it over your body as a final rinse after you finish bathing or showering.
To remove more buildup from your hair, mix 3 to 4 US tbsp (44 to 59 mL) with 2 c (470 mL) of water. After shampooing, apply the mixture from your roots to tips. Let it sit for 10 minutes, then rinse and apply conditioner as normal.
Try to avoid using ACV as a rinse if you have open wounds or cracked skin. The acidity might increase irritation.
Relieve eczema by mixing 1 c (240 mL) ACV into a tub of lukewarm bath water, soaking the affected areas for 15 to 20 minutes, and rinsing with cool water.

Install an ion exchange shower head filter.
Download Article
It will remove chlorine and other minerals from your water. Shower filters are also effective at neutralizing unpleasant smells, and they are specially designed to work with high temperatures and flow rates. To install one, remove the old shower head and follow the instructions provided to install the new one.[10]XResearch source
Some online shower head sellers may make misleading claims about how much they improve water quality.[11]XResearch source Look for filters that include evidence to back up their claims.
To know exactly what minerals your water contains, try testing it with water hardness testing strips. You can pick up testing strips at your local hardware store.
5
Add washing soda to your laundry.
Download Article
Washing soda, or sodium carbonate, can temporarily soften your water. When you throw a load into your washing machine, sprinkle washing soda over your clothes to reduce calcium and magnesium in your laundry. Washing soda also helps lift dirt and grime from fabric, so it can lead to cleaner clothes.
The carbonate ions from washing soda dissolve the calcium and magnesium ions in hard water, leading to softer water.
Try to only use washing soda in your laundry, not anywhere else. Long-term washing soda use can lead to limescale buildup, which can clog pipes in heating systems.
You can also add ¼ cup (62.5 g) Epsom salt to your laundry to soften the water.[12]XResearch source

Use vinegar to remove hard water buildup.
Download Article
Descaling your faucets can extend their lifespan. Hard water can lead to limescale buildup, which reduces water pressure in faucets. To descale a shower head or faucet, fill a plastic bag with distilled white vinegar and attach it to the opening with a rubber band. Wait 1 hour, then remove the bag and rinse the area.[13]XResearch source
Hard water can also lower the efficiency and lifespan of appliances that use water, like coffeemakers and fridges. Consult each appliance’s manual to see how to descale it.
House cleaning professional Andrii Gurskyi says you can remove orange residue in the shower from hot water by scrubbing it with white vinegar, hot water, and a toothbrush.[14]X Expert Source Andrii GurskyiHouse Cleaning ProfessionalExpert Interview
Aim to descale your faucets, appliances, and other areas prone to buildup once a month.
7
Install an ion exchange softener for your entire water supply.
Download Article
These kinds of softeners are usually installed by a professional. Ion exchange softeners have resin beads that water flows through and traps excess minerals.[15]XResearch source For whole-house softeners, you may be required by law to hire a professional who can install it in your home.[16]XResearch source
Home ion exchangers are ideal for hard water rated medium to very hard. They are one of the most common choices for improving household water.
You may want to run a hard water test first to note the kinds of minerals in your water. Some softening systems may be better at removing certain contaminants than others.
Prices vary according to model and region, but these kinds of softeners generally run between $500 and $6,000.[17]XResearch source

Use a reverse osmosis filter in aquariums.
Download Article
It will purify and distill your water for happier, healthier fish. Install a reverse osmosis filter on the back of your fish tank and make sure it’s plugged in. The filter will separate the impurities from the water and leave only the softened water in your tank.[18]XResearch source
Most aquarium-sized reverse osmosis filters cost around $60.
There are reverse osmosis filters that can fit on your home’s water supply—the average cost of these is around $2,200.[19]XResearch source
9
Place driftwood in an aquarium.
Download Article
Driftwood releases tannins that naturally soften water. Pick up a log of driftwood from a beach nearby, then boil it in water for about 5 minutes. Let the log cool and then place it in your fish tank to naturally soften the water over time.[20]XResearch source
Driftwood can also decorate your tank, help anchor aquatic plants like Java fern or moss, and provide shelter and comfort to your fish.[21]XResearch source
Advertisement 10
Add peat moss to an aquarium.
Download Article
Peat moss naturally filters hard water and purifies it. Purchase a layer of peat moss from an aquarium store and place it at the bottom of your tank. Over time, the humic acid and the tanning agents in the moss will soften the water and filter it.[22]XResearch source
Peat moss may turn your water a slightly yellow-green color; however, it doesn’t mean the water is dirty.
Try not to lower the pH of your water for hard water fish species like guppies or mollies.[23]XResearch source

To soften hard water naturally, get a filter installed, or for a short-term solution, try boiling your water before you use it. If you drink water straight from the tap often, consider installing a drinking water filter in your kitchen to remove impurities. Some filters attach directly to your faucet, while others act as filters for pitchers. If you only want to soften small amounts of water at a time, fill your kettle from your faucet and boil it. Let the water cool completely, then transfer it to a container with a baster, siphon, or ladle. Try to avoid any sediment that gathers at the bottom. To stop your boiled water from tasting flat, pour it back and forth between 2 clean containers for a few minutes, which will restore oxygen to the water and improve its taste. If you want to soften your shower water, get an ion exchange shower head filter from a hardware store. These filter chemicals, like chlorine and lead, from your water.
