You probably grew up thinking cotton swabs were the ultimate wax removers. But you've heard it before (assuming you're not suffering from hearing loss): Don't stick any spear-like objects (aka Q-Tips) into your ear, as they can perforate your ear drum. Jaw movement naturally forces your ear canal to move and dislodge wax (though we don't suggest a taffy diet to do so). If you experience buildup, you can remove the wax with an over-the-counter softener like glycerine. Or put mineral oil in your ears, let it sits for 60 minutes, then gently flush with saline warmed to body temperature, or just let it fall out on a piece of cotton.
You can also see a doctor, who may try to remove it through a vacuum-like device, which is safe if done by an experienced practitioner. The vacuum technique is much safer than a method that used to be commonly used: flushing the ears out with water and high pressure. The water, if not the right temperature, can cause dizziness, and the high-pressure flooding can damage the drum.
