There are lots and lots of threads on this topic! Personally, I use only vinegar and water and baking soda to clean my house. I use vinegar and water mixture to clean anything that does not need to be scrubbed (countertops, sink, toilet, floors, etc.) and baking soda for things that need to be scrubbed (stovetop, bathtub, kitchen sink, etc.). My advice would be to use vinegar and water for anything you normally would clean with a spray cleaner and baking soda for anything you normally use comet or the like.
