I use Bi-o-Kleen’s cleaner / degreaser for everything except windows and laundry. It’s really economical when you buy it in bulk, and it works better than other cleaners I’ve used. I use it in various dilutions for everything from produce to my Floormate.
Their premium laundry soap is also a steal @ 18 cents or less per load and it has an oxygen cleaner in it so you never need additives. I use only half the scoop for permanent press, too, so that saves!
Vinegar & water for windows, of course, as CSinbad mentioned!
