Oh dear no.. not sure how safe it is. The best way to get your ears cleaned is to go to the doctor and let them do it! (trust me, everything will sound much clear after)
Well yeah I dont see how water in your ear could hurt unless its really high pressured, but ive been doing it all my life when I wash my ears and such.
Find an elephant take it to the river he drinks the water then sprays it in your EAR from his trunk, then when you get up after being knocked to the floor by the force Your Ears are then Clean
I rarely clean out my ears. I usually rub them down a little bit while in the shower, but I don't use q-tips or put anything inside of them. My wife says i'm deaf though...
