When I hit 40 I would get ear infections every time I spent more than a couple hours a day in the water. Then I started using the recipe below after EVERY dive. I haven’t had an ear infection in 24 years. I always have a bottle on board and in my truck. I just take the cap off hold my finger over the opening and let a small amount go down into each ear.
All the materials are available at any drug store for less than $5.00. The Alcohol dries the water, The boric acid is what your grandmother used for infections and the white vinegar keeps the wax from drying up because of the alcohol.

Ear wash recipe
1 Pint 70% or less % Isopropal Rubbing Alcohol
Boric acid powder 6 oz. is more than enough
White Vinegar


Pour out about 2" of the alcohol out.

Pour or put about 3 Table spoons Boric acid into Alcohol and shake up. If acid remains in powder on bottom you have enough if not add until a small amount remains on bottom. Only a certain % will go into solution so you can't overdue the Boric Acid.Fill the remaining area in the bottle with white vinegar and shake up. The solution is now ready to use.

I usually buy 3 or 4 bottles of alcohol and mix them up in a big bowl then pour them back mixed up into the alcohol bottles. This way the powder on the bottom remains in the bowl and won’t make your ears white when the solution dries out after pouring it into your ears.

whats the shelf life?

the simple treatment for otitis externa or swimmer's ear is acetic acid, or dilute vinegar, to prevent the growth of bacteria. the alcohol helps dry the water out.


"Effective solutions for the ear canal include acidifying and drying agents, used either singly or in combination.

Burow's solution is an effective remedy against both bacterial and fungal external otitis. This is a buffered mixture of aluminum sulfate and acetic acid, and is available without prescription in the United States."

What's the shelf life.

Yes that's me back in 65 in Diving school. As for the stories, I am still in the process of building more as I dive every chance I get.
Thanks
