Using soap or detergent on a seasoned pan is a no-no. Which is probably why yours is not being very non-stick.

Honestly, I don't think I'd use steel wool, either, as it's going to leave scratches for food to get stuck in.

I've always heard to use salt, but I've not had much success with that.

Try plain baking soda. It's mildly abrasive and will soak up any excess oils, water, and other liquids.
