We accidentally wiped a cotton dish towel across our new, black glass cooktop when it was hot and a baked-on residue formed.

Try making a paste of baking soda and water. Apply and leave on for at least hour, or maybe over night. Then scrub off. The baking soda shouldn't scratch!
I had a glass top electric stove. Use glass top cleaner and a rag that has been dampend with hot tap water to scrub it away.
