I've been collecting recipes for homemade cleaners for a while now. My favorite post on homemade (EASY!) cleaners is What's Under My Sink by Katie at Kitchen Stewardship - she uses baking soda, vinegar and peroxide. Click over to read about how spraying vinegar followed by peroxide (or vice versa) and letting it dry is as effective as using bleach!
My mom loves the smell of vinegar. I think she once told me that it smells clean to her. (Is that right, Mom? Or does it smell yummy as in salad dressing? :>)) Anyway, I don't quite agree, though vinegar is growing on me a bit as I've been using it more for cleaning. One of my favorite smells is citrus - you can read how I even use it to combat motion sickness here.
I found an article at Tipnut quite a while back on making citrus vinegar for cleaning, and gave it a whirl. We don't eat a lot of citrus, so in the wintertime when we enjoy clementines, I save the peels and let them dry. I begin by washing the fruit with a dab of dish soap; Tipnut has a link to a fruit and veggie cleaner on the vinegar post, or you can read Katie's experiment with several different methods of cleaning at 8 Ways To Wash An Apple: How Well Does Produce Wash Work?.
Last year, I laid the peels on the counter until they were dry and then tossed them in a bowl; then when we'd worked our way through the clementines, I put them in the vinegar. This year, I tossed them in the bowl without letting them dry and there were a few that I thought might have been moldy (I threw those away). Live and learn. I suppose it also wouldn't hurt to put them in the vinegar as you accumulate them, but I'd add some time to the four weeks of "brewing", still making sure to shake it every day.
Once the four weeks it up, you strain it a time or two, and your citrus vinegar is ready to use! If you hate the smell of vinegar, this might be enough that you can use it in your green cleaning routine. I have come to enjoy the smell of the citrus stuff, at least.
