To clean ears at home safely, it's recommended to use a gentle solution such as a mixture of warm water and hydrogen peroxide. Avoid the use of cotton swabs, as they can push earwax further into the ear canal, potentially leading to complications. Instead, let the solution soften the earwax naturally, and then allow it to drain out on its own. If you're experiencing excessive earwax or discomfort, consult with a healthcare professional for personalized advice.
