Hydrogen peroxide is a cerumenolytic, which means that it can soften, break down, and dissolve earwax. Earwax is a waxy substance secreted in the ear canal that is a natural cleanser with antifungal and antibacterial properties that help protect the ears. However, too much earwax can cause problems such as infections, earaches, ear discharge, hearing difficulties, ringing in the ear, or itching inside the ear. Hydrogen peroxide can help remove earwax by adding oxygen to the wax, causing it to bubble and soften.

It is important to note that earwax only needs to be removed if it becomes impacted, which can cause symptoms such as earache, itchy ear, infection, hearing loss, tinnitus, and vertigo. Impacted earwax should be removed at a doctors office by an expert. If you feel your earwax is unsightly or you want it gone, there are safe ways to clean it at home.

While hydrogen peroxide is generally safe to use in low concentrations, some people experience side effects such as pain, itching, or irritation. It is also important to use hydrogen peroxide properly and to avoid using it if you have a perforated eardrum or grommets, or if you experience pain on administration. If you are unsure about using hydrogen peroxide to remove earwax, it is best to consult a healthcare professional.
