Gather your supplies: You'll need table salt (preferably non-iodized) and warm water. Ensure that the water is warm but not hot to avoid burning your mouth or throat.
,
Measure the salt: Use about half a teaspoon of salt for every 8 ounces (240 milliliters) of water. This concentration is typically effective for gargling.
,
Boil the water (optional): If you prefer, you can boil the water first to sterilize it, but this step is not necessary if you're using clean tap water.
,
Mix the salt and water: Stir the salt into the warm water until it dissolves completely. Make sure the solution is well-mixed before gargling.
,
Take a sip of the salt water: Take a small sip of the salt water solution and hold it in your mouth.
,
Tilt your head back: Tilt your head back slightly to allow the salt water to reach the back of your throat.
,
Gargle: With your head tilted back, gargle the salt water in your throat for about 15-30 seconds.
,
Spit out the water: After gargling, spit out the salt water into the sink. Do not swallow the solution, as it may contain bacteria and debris from your throat.
,
Rinse your mouth: After gargling, rinse your mouth with plain water to remove any residual saltiness. You can also brush your teeth afterward if desired.
