mason jars, and the fact that I don't have to worry about chemicals leaching from plastic. I found this jar at our local Goodwill for only 96 cents! You can get an even better deal right now on Amazon - 12 Ball® Pint Jars for under a dollar each!
Fill the jar with white vinegar, and just keep adding orange peels (or any other citrus fruit peels) to the jar as you eat them! I'm sure mine will be full very soon :)
Then I'm going to wait two weeks, and mix 1 part of my orange vinegar solution with 1 part water, and start busting some scum!
I can't wait to see how it works, and share! What about your greener cleaners? What natural products have you made at home?
