"This trick is also good to use before/after wearing earplugs for an extended time (i.e. on a plane flight, all night in a noisy hotel). I think it helps by creating a sterile environment, preventing nasty bacterial activity that could otherwise occur in a sealed environment. Also kills bacteria on your fingers that you use to roll up the earplugs.Be sure the drops in your ear have evaporated completely (wave your hands) before inserting earplugs." - comment submitted by jaime9999.
With that out of the way, let's get going!
Step 1: Gather the Materials
1 small bottle of Vinegar
1 small bottle of Alcohol
1 eye drop container (or anything with the ability to distribute drops)
1 Funnel (make sure it fits the eye drop container)
Step 2: Combine the liquids
Fill the bottle with 1/2 Alcohol
secure the cap back onto the bottle.
Shake well to mix.
Step 3: Finished!
All you have to do is put four drops in each ear after swimming. (then tilt your head on to a towel to get rid of the water)
Go on to the next step to see a label that you can add to it.
Step 4: Label your Bottle
The vinegar is a good preventive since it restores the ear canals acidity. The vinegar is mainly to water down the alcohol so there is less or no discomfort younger children's ears. The alcohol is the main ingredient to flush out the water and help with the evaporation of any water left over. Be sure to replace the formula every now and then with a new batch. I'm sure you don't have to worry about it, but I'm sure it gets old eventually.
