I wouldn't try to remove anything, just go through the process again. It's important to make your film of fat really thin, or it won't work properly.
I use my cheap cast iron frying pan pretty much every day. I don't follow 'best practice', but have no issues with sticking. I wash it with detergent (stir-fry flavoured pancakes are weird!), rarely use animal fats, and my flatmate even hits it with the scourer sometimes. Gasp.
After cleaning, I dry it immediately on the element (easy, as it lives there), then wipe it very sparingly with veg oil on a piece of old towel.
If something sticks, I soak it while it's still hot, or heat water in it, then wash. Obviously, if anything sticks, ever, I don't have the best-seasoned pan, but it's generally not an issue.
