1] put a waterproof barrier over shoulder/neck.
2] mix 1/2 warm water with 1/2 peroxide.
3] lay on side, with affected ear up; or just lay head on side.
4] gently put one eyedropper full of fluid into ear. Let sit for 5 - 10 minutes. Put another few dropperfuls in, until fluid starts rushing out.
DO NOT put anything in the ear - no Qtip, no toothpick, no bobby pins, no hair pins, etc.
The only person who should do this is an ear doctor, who has the correct instruments to do it without injuring your ear.
If you still have something in there, see a clinic.
