Saline solution is handy for tasks like cleaning piercings or irrigating your sinuses, but it can get inconvenient to go out and buy more every time you run out. How can you make an effective solution at home? “Normal” saline is about 0.9% salt and is a breeze to make yourself—all you need is boiled or distilled water and non-iodized salt. [1] X Research source We’ve put together a step-by-step guide to making a 0.9% solution, including slight variations in the recipe to target your sinuses, piercings, or mouth. Read on to get started!
Things You Should Know
- Boil your saline container and mixing utensil for 10 minutes or run them through a full dishwasher cycle to sterilize them.
- Mix 2 teaspoons (8.4 g) of non-iodized salt in 4 cups (0.95 L) of distilled or boiled water. Wait until the solution is room temperature to use.
- Use homemade saline to clean wounds and piercings, irrigate your sinuses, rinse your mouth, or clean out your ears.
Steps
-
Boil 4 cups (0.95 L) of tap water in a sterilized pot for 5 minutes. Add water to the pot directly from the tap or with a sterilized measuring cup. Once boiling, let the water roll and bubble for at least 5 minutes to eliminate bacteria. Turn off the heat and let the water cool to lukewarm. [2] X Research source
- Alternatively, use or purchase distilled water to skip the boiling process.
- If you’re in a hurry, microwave the water in a covered container for 2 minutes until it’s boiling or almost boiling.
- Plan to use the water quickly after boiling. If it sits too long, it will collect bacteria again.
- Avoid using well water or sea water, since these contain more particles and germs than you get from your tap.
-
Stir in 2 teaspoons (8.4 g) of non-iodized salt until it’s dissolved. Regular table salt grains are small enough to dissolve easily in hot water. If you’re using sea salt, opt for small grains or flakes rather than large crystals. Stir while the water is still lukewarm to help the salt dissolve. [3] X Trustworthy Source Cleveland Clinic Educational website from one of the world's leading hospitals Go to source- If you’re making saline for oral swishing , add 4 teaspoons (16.7 g) of salt and 8 teaspoons (33.5 g) of baking soda (the baking soda makes the solution less abrasive). [4] X Research source
- For nasal irrigation , add 3 teaspoons (12.6 g) of salt and 1 teaspoon (4.2 g) of baking soda. [5] X Research source
- To clean piercings , add 1 teaspoon (4.2 g) of salt (super salty saline may irritate the piercing more than it helps).

Wait until the solution is room temperature to use it. This keeps you from burning or irritating your skin, wounds, or orifices. [6] X Research source To transfer the saline to a syringe or irrigating tool, pour it directly from the pot into a clean paper cup , then dip your syringe into the cup. [7] X Research source
- Avoid dipping non-sterilized tools or utensils directly into the solution.
-
Store extra saline in an airtight container for 3 days at room temperature. Pour leftover solution into a tightly covered glass or plastic container and label it with the date. [8] X Research source After 3 days, dump any remaining solution, re-sterilize the container, and make a new batch if needed.

Clean wounds with a gauze pad dipped in saline. Put on disposable gloves and place a towel underneath the wound. Dab the wound in a circular motion, working outward from the center to prevent germs spreading inward. Use multiple pads if needed to remove all debris and draining liquids. [10] X Research source
- Pat the wound with a clean, dry cloth to dry it.
- Throw away your gloves and saline-soaked gauze after cleaning.
- Apply a new dressing to the wound if necessary.
-
Irrigate your sinuses with a neti pot or soft rubber ear bulb syringe . Draw 8 fluid ounces (240 mL) of saline into the bulb or syringe. Lower your head over a sink (or in the shower) and rotate to the left so your right nostril is raised. Squeeze half the solution into your right nostril and wait a few seconds for it to come out of your left. [11] X Trustworthy Source Cleveland Clinic Educational website from one of the world's leading hospitals Go to source
- Repeat this process through the other nostril.
- Breathe through your mouth while the saline runs from one nostril to the other.
- Blow your nose gently to keep the saline from running into your ears. If it does, it’s OK—the mild discomfort will go away after a few minutes.
- Irrigate at least 30 minutes before applying any other nasal medication.
-
Clear out earwax with a cotton ball dipped in saline. Tilt your head to one side and drip saline into your ear from the soaked cotton ball. Let the solution sit for a few minutes, then tilt your head the opposite way to drain it out. Repeat in the other ear. [12] X Research source
- Alternatively, add saline to your ears with a small syringe. [13] X Trustworthy Source Cleveland Clinic Educational website from one of the world's leading hospitals Go to source
-
Swish saline in your mouth for 30 seconds to relieve oral pain. Simply rinse a mouthful of solution around your teeth and gums 2-3 times per day, then spit it out. The saline acts as an antiseptic to kill bacteria and speeds up healing for oral wounds and sores. [14] X Research source
- Also try gargling saline to soothe a sore throat.
- Homemade saline is non-toxic if you accidentally swallow it.
-
Soak piercings for 5-10 minutes daily to clean and disinfect them . Pour saline into a small cup or shot glass and invert it over your piercing to form a vacuum. If the location makes this too difficult, use a cotton pad or paper towel that’s dipped in saline to clean the piercing site or add your saline to a spray bottle. [15] X Research source
- Dry the piercing gently with clean paper towels.
- Avoid using cloth towels since they contain more bacteria (and are more likely to give you an infection).

Tips
- Use less salt in your next batch if you experience burning or stinging with a 0.9% salt solution. [16] X Research sourceThanks
- Before starting, wash your hands and sterilize your mixing equipment. Gather a pot to boil water in, a container with an airtight lid, and a mixing utensil. Give them a quick hand wash to get rid of any spots, then run them through a full cycle in the dishwasher or boil them for 10 minutes. Boiling water kills germs and bacteria on your equipment that might contaminate your sterile saline solution.Thanks
- Make sure your equipment is dishwasher-safe or safe to be boiled before sterilizing. Aluminum cans or paper cartons will melt or fall apart, for example. Use stainless steel pots and stirring utensils to prepare your saline—they’re safe to boil and easy to sterilize.Thanks

To make a saline solution, start by bringing 1 cup of water and ½ teaspoon of regular table salt or sea salt to a boil on the stove. Make sure you use salt that doesn’t contain iodine or preservatives, which can irritate your skin and nasal lining. Next, let the solution boil for 15 minutes, then allow it to cool before using it. Alternatively, store the solution in a sterile jar or bottle so that it stays effective until you're ready to use it. For tips on how to make your saline solution weaker for a child or stronger for an adult, keep reading!
