My mother tends to have a lot of ear wax in her ears, which causes her to not hear properly. What is the best way to clean her ear wax? She's also 71 years old.
If necessary (and in many or most cases it isn't), you can use various over-the-counter ear wax cleaning kits. If this is unsuccessful or undesired, then you can have her see a doctor.
Take her to an ENT Dr to clean her ears
