There are a few different ways to know when to stop posting your ears. The most reliable way is to use an earwax removal kit that has a light and magnifying glass. With this tool, you can see the wax build-up in your ear and determine when it is time to remove it.
Another way to tell if you need to remove earwax is by using a cotton swab. If the cotton swab comes out clean, then there is no need to remove any wax. However, if the cotton swab has wax on it, then it is time to remove the wax.
The last way to tell if you need to remove earwax is by looking in the mirror. If you see any wax build-up on the inside of your ear, then it is time to remove it.
