Cleaning your stove glasstop with baking soda and warm water and soap.  I seen this on pinterest and thought I'd try it.  Just sprinkle baking soda on the stove top. Have a bowl of warm water and dish soap ready.  Place a towel in the soap water and squeeze just enough to be soppy but not all the way rung out.  Lay on top for 20 minutes.  Take the towel and wipe around the entire stove top, no muscle needed, just scrub gently.  If you see a spot that didn't come up all  the way, sprinkle a little more baking soda on that one spot and use the same towel to scrub gently.  Wife off and spray with windex or other glass cleaner and wala.  If you've let your stove go way far beyond, you may need to repeat and then a couple times a week should do it.  Very inexpensive.
