Making your own cleaners is a great way to save money and avoid lots of nasty chemicals. Ask your Mom or your Grandma and I bet you'll learn that they cleaned house just fine without things like:
Cocamidopropylamine Oxide, Propoxypropanol, Alkyl C12-16 Dimethylbenzyl Ammonium Chloride, Dimethicone/Silica/PEG Distearate Antifoam (Formula 409)
(My spell-checker nearly had an aneurism with all those chemical names. Does anybody else think they sound sinister and poisonous, or is it just me?)
My favorite all-purpose cleaner is vinegar. It breaks down mold, grease, mineral deposits, and it's anti-bacterial. (Don't use it on granite, tile, or marble though.) Unfortunately, BrownThumbPapa thinks it makes the house smell like a salad. What's a girl to do?
Citrus peels to the rescue! Since they don't break down easily in the compost bin, I had been throwing them away (with all the associated guilt that entails). After a bit of research, I learned that citrus peels contain a natural oil called D-limonene. It's a great degreaser, stain remover, and it smells good too.
Now, after peeling any citrus fruit (oranges, lemons, limes, grapefruit) I put the peels in a large jar of white vinegar. The peels steep for a week or two, and I strain them out when adding vinegar to my homemade cleaners.
