One teaspoon of boric acid powder to one pint of rubbing alcohol (70% solution). Shake to dissolve. Apply 4-5 drops to the ear; leave the solution in for 5-10 minutes.

Stop if it stings when applied to the ear.

I've been using white vinegar and rubbing alcohol 90%. I mix them 50/50.

Take the following recipe to the pharmacy:

Aqueous Solution: 8 parts of aluminum acetate solution BP with five parts purified water, freshly boiled and cooled; or Nonaqueous Solution: 2 percent acetic acid, in a propylene glycol vehicle containing propylene glycol diacetate 3 percent and sodium acetate 0.015 percent.

There are a lot of solutions out there - and a lot of threads about this..! Basic do it yourself solutions are mainly alcohol (to dry the ear) with something to make the pH low (to discourage growth of Pesudomonas bacteria, a common ear canal bug).

The usual acidifying agent is white vinegar. Boric acid is used in outer ear infections, but typically as a powder, which is blown into the ear canal using an insufflator. Powders work well for ear infections, but are not as commonly used for self medication as they are harder to keep dry, and are not FDA approved. The reason that they are not FDA approved has less to do with safety and more to do with the fact that there isn't a big market for them, so it's not worth the (major) cost of getting FDA approval.

CSF-HC (chloramphenicol, sulfanilimide, amphotericin with hydrocortisone) powder works great, but it's hard to get an not over the counter...
