Are deep blackheads even possible to remove?

I've had these since I was 10, and I've tried everything. It's really frustrating. ): My blackheads are too deep for Biore strips or squeezing/popping. Scrubbing them doesn't get rid of them. I've tried the oil cleansing method, but that only removes 1-2 small blackheads. I keep very good facial hygiene, and I don't overwash my face. I'm beginning to think that it's impossible... personal experiences on what really works?
