nope, disagree...and a small amount of ear wax is actually healthy
A couple of years ago Misty had to have a grass seed removed from her ear and the vet found a couple more tiny ones, which he thought had probably been there for some time - he reckoned the wax had stopped them from working their way into her ear drum.
This is exactly what my vet said when Milo got a grass seed in his ear a couple of years ago. He went to roll in a cowpat and managed to rub a seed into his ear.

The vet said if he didn't have a healthy deposit of wax in his ear, there was every likelihood that it would have perforated his eardrum.
Had a bit of a scare this morning too, Milo came back to us while on a walk, with the tell-tale head shaking and holding his head to one side. When I looked in his ear, there were a couple of small seeds just outside the ear canal. I managed to get them out with my finger but only because they'd got "stuck" in a bit of wax. If his ears were spotlessly clean, I'm sure they would have gone straight down.

I do clean their ears regularly and they're due a clean about now, but ear wax is there for a reason!
