In ears also dont stop your ears from self cleaning, just means the final stretch has to be washed out i guess. As you do. Dont shove paperclips in there.
And consider over/onear headphones maybe.
People should get to know their bodies and stay healthy. If I do not do these things I just described, by the way, I start to lose hearing after a few months.
Yes they do, through education and medical advice. Not by sticking things into their holes.
If you got crazy buildup despite washing, you need to speak with a doctor too.
