This is random (surprise), but currently my two favorite cleaning supplies are Cascade Complete Dishwasher detergent and Mr. Clean Magic Erasers.
The Cascade Complete just gets my dishes cleaner. (I know, I sound like an add, but it's true.) I am lazy (um, efficient) , so I don't like to pre-rinse my dishes execpt when they are really bad. The Cascade lets me get away with that.
I also love the Magic Erasers. I have gotten so many crayon and marker stains off my kitchen table due to it's ability to get weird stuff off surfaces.
