Cleaning a Glass top Stove

I've has a glass top stove for years now. I used to buy the cleaner made specifically for it to keep it looking good. As I've said before, I try to be as frugal as possible. In other words, I'M CHEAP! I came across this method a few years ago and it works great.

Recipe:
Baking soda
Rag
Hot water

Sprinkle baking soda on the stove top. Be careful not to use too much or it makes cleanup harder. Wet rag with hot water, as hot as you can stand. Wring out rag leaving it wet but not too wet. Place rag over baking soda and let it sit for a few minutes. This loosens any food that may be stuck on. Then, gently scrub area with rag and wipe clean. Does the same job as the expensive store bought cleaner at a fraction of the cost.
