I have a glass top stove. Not on purpose. It came with the house. If I had my pick, I'd choose a gas stove any day. Not only do I like cooking with gas (yes!), I can make a mess and ignore it, but I digress. Cleaning my glass top stove has been a bit of a struggle for me. No ignoring those cooked on messes. The store bought stove top cleaner especially made for glass top stoves is crazy expensive and um, no thank you. The blade like scraper that came with the oven must have moved with the last tenants. I was left with a dirty glass top stove that I made dirtier by not caring for it properly. Of course, I had no idea how to make it better.

Thank goodness for the internets. I don't remember where or how, but I stumbled across a gajillion and one ways to clean a glass top stove somewhere and I've adapted what I learned from all those places on the world wide webs. Of course, my way is cheaper and easier. Natch.

Peace, B. 

The good news is, it will come off. The bad news is, you're gonna need to scrape the hell out of it with a razor blade. I was just thankful to find a frugal replacement for the snazzy missing scrapers they sell specifically for glass top stoves. If you clean up spills right after they happen (and while the stove top is still warm), you won't have such a daunting task before you- like the one I had by the time I realized that I'd cooked on a mighty mess around each of my four burners. 

Once, you've scraped away the gross-ness that was on your glass top stove, just keep those messes wiped up as best you can. Before it gets to the scraping stages again, you can use a hot water/dish detergent/ baking soda mix that works wonders. I learned all about that here.

The most effective cleaner I've found for just wiping down and keeping my glass top stove shining is my homemade window cleaner.
