How to get baked on gunk off glass cookware?

I have an Anchor Hocking glass baking dish. Thanks to frequent use, and children doing dishes, it has baked on dirt. I can’t seem to get it completely off. I’ve tried scrubbing, and even soaking in bleach. It still has ugly brown spots as well as being tacky to the touch. Any good old fashioned remedies for this? I really don’t want to go out and get some speciality cleaner just for this one dish.
