Here is my favorite cleaning tip of the year, given to me by my sister-in-law. Steam cleaning courtesy of the microwave. (Not how to clean a microwave - we all know that trick.)
Let's say you have a stainless steel cook top with dried on food. If you use any kind of cleaning product on this it streaks and even with cleanser it takes a lot of scrubbing.
Get a clean washcloth really damp.
Cook in microwave for 1 minute.
It will be steaming hot. (I use a dish towel to get it out of the microwave because it is so hot.) At this point your washcloth is a steam cleaning machine.
It will get your stainless steel cook top spotless in less than a minute.
