Question: can you use kosher salt to make saline solution?
Answer: To make the solution, mix 3 teaspoons of non-iodized salt (kosher salt with no additives is best) and one teaspoon of baking soda. Store this mixture in a small clean jar. When you are ready to use it, mix a teaspoon of the mixture into 8 ounces of distilled, sterile, or previously boiled and cooled water.
