I'm all for cleaning an environmentally safe and healthy as possible! I started trying a lot of different things in the last year - not just for cleaning, but for bath & body products and makeup too! Everyone has already named a lot of the things I would have already mentioned - Things that are a must in your Green cleaning cabinet (especially if you are going the budget route!) Big jugs of Vinegar - you will use it a lot, same with Baking Soda - biggest box they have!, I also use Borax a lot for scrubbing tough areas and for boosting laundry brightness, and a number of other things, Washing Soda is also very good - its kind of a stronger form of Baking soda, get a very gentle concentrated cleaner you can mix yourself in different strengths and with different things if needed - I like Mrs Meyers, and Dr. Bonners is great too - its Fair Trade Castile Soap that is great for both cleaning and for bathing and comes in many scents. You will find probably that the name brand cleaners like Mrs Meyers and Dr Bonners may not be as cheap as you would like, but keep in mind they are very concentrated and they will last a long time. Stock up on your on spray bottles, microfiber cloths, they have green recycled sponges and scour pads now too! I would also stock up on either a set or just a few of your favorite scents of different essential oils - they can make a big difference to the smell of your cleaner, and some have their own special properties. I love sweet orange, lavender, peppermint, tea tree, lemon, rosemary, just to name a few - I would compare prices places before buying, and make sure you get 100% pure oil - not oil that has been mixed with anything at all. These are great too if you get into making your own bath salts, lotions, foot baths, etc. There is so much you can do! If you get interested in checking out natural/organic beauty products: I love Organix for shampoo/conditioner, Dr. Bonners for liquid bath soap, Method for hand soap, and my absolute favorite is for makeup - I love Tarte Cosmetics for makeup - they are a great natural makeup - you can find it at Ulta or Sephora. I also forgot to mention that I like for my laundry tabs, dryer wet cloths, a dishwasher tabs a brand called GrabGreen - I have only found them online - both on Amazon.com and Drugstore.com. Amazon has a lot of great books about going green cleaning and in general. You can also google Green Cleaning and get lots of cheap homemade recipes that work. Treehuggers.com also has some great recipes on it too! Good luck and good for you! You'll fee so much better!!!
