Glass is tough to remove scratches from, and I'd leave it to the pros. While steel wool can reduce the depth, it will likely leave a little scuff on the glass which can look worse than the initial scratch.
Novus is a company that I've used to fix glass problems in the past, and they are nationwide. I have no affiliation with them, just had success with their process of buffing glass. It's a specialized process and the right training, tools, and technique are worth the extra $$. Look online for replacement value of the glass first, as scratch repair can cost upwards of $100.
My $.02, and hope this helps.
