Clogged pores? Help!?

I have really clogged pores. Like when I squeeze my skin stuff comes out. It's mainly on my nose area. I wash my face twice a day and I don't have bad acne. My pores are just so clogged! I've used stuff to clear them and it works but the next day they are clogged up again. It doesn't have anything to do with my makeup I think cuz I've gone days without wearing any and I still get the same results. How can I make my pores stop clogging and why do they clog so much? Ps: I don't do any like sports activities or anything that would make me sweat a lot but I have oily skin
