Does cleaning your ears increase your risk of ear infections

[Wesley Clark]

Products that contain carbamide peroxide like ERO help to dissolve ear wax inside the ear canal, but does using those products increase the risk of ear infection? I know that one of the purposes of wax is to catch bacteria and move them out of the ear, w/o the wax aren't the bacteria going to have a stronger effect?

Then again it was my understanding that a lot of ear infection was due to the eustachian tubes getting clogged and I don't know if removing earwax would make a difference in that.
