Well I don’t know about baking soda, but I will say that I’ve discovered that good ol’ hydrogen peroxide is the best way to get rid of ear wax AND it kills germs by the bushel.
Also, on those occasions where I’ve had a bad cold bug that was trying to move down into my lungs, I added a 500ml bottle of hydrogen peroxide to a cold water room humidifier, turned it on before bedtime, and in the morning I would be coughing up and getting rid of all sorts of mucus and junk.
Now I’m not about to say that hydrogen peroxide is all you need because there are situations where you HAVE to get yourself to a doctor but I know what has worked for me, maybe it will help someone else.
Thank you for the tip on ear wax. I often have a nasty ear wax buildup and resort to using my Water Pik with hot water. It is an unpleasant experience. The use of hydrogen peroxide would be a great solution for my problem. Do you dilute it? How long do you let it sit in your ear?
