well, i'm basically copy and pasting my response from the post "what's the best green cleaning products"
the cheapest and best most definitly are

Vinegar, Essential Oils, Baking Soda, Citrus Acid, Washing Soda, Castile Soap (which i make from sratch from oils, milks and lye- but you can buy it too, or use whatever bar soap you like), Lemon Juice, Oils and Hydrogen Peroxide. ;-)
These are what are used to clean with in my house. Some jobs just require one ingredient, some a mix of a few of them. But it's cheap and easy to do. most people say they don't have time to make their own cleaners, invariably I find these people have never tried, it's amazingly simple and quick to make all the recipes I use, and the work just as well as store bought or better- and oh so much cheaper!
just remember to go with baby steps so you don't overwhelm yourself. if you need help with some easy recipes let me know, I would be happy to help and post the ones that work for me, and give any tips on tweaking them you might need.
good luck and congrats on your choice to live a little greener ;-)
