Re: Ear drop solution

Hello Iloveamma,

The easiest way to make a solution that is very close to 10% citric acid is to put 1 part crystals and add 9 parts water.

For example you could measure 1 level teaspoon of citric acid crystals and add 9 level teaspoons of water.

The correct way is to measure by weight. For example 1 gram of citric acid crystals would be added to 9 grams of water to form a 10% (by weight) solution.

Making it using volume measurements will get you very close and this will be good enough for what you are doing.

Be sure to clean and disinfect your ear plugs after every use.
