I WONDER - How Do Our Ears Keep Clean?

Ears can accumulate dirt, bacteria, and dust, leading to irritation and hearing issues. To combat this, ears have a self-cleaning mechanism that involves producing wax to trap and expel debris. Ear hairs also play a role in trapping dust. While some people may need to clean their ears due to excess wax, the ear generally maintains its cleanliness naturally.

What helps in the process of trapping dust in our ears?

Why might some people need to clean their ears more frequently?
