We compost, so I don't feel like the orange peels were being wasted when they are tossed in with the other food scraps, but this seems to make even better use of them. I often candy orange peels to use in cooking, but the process is time consuming and I don't use most of my peels in this way. Now I am happy to toss the peels into the jar and know they are being put to a great use.
Peel the oranges and throw peels into a jar.
Pour enough vinegar to cover. Continue to fill the jar with peels and vinegar and let sit 2 weeks.
Strain the vinegar and return to jar.
When you use the cleaner, dilute with 3 parts water.
I pour about 1 cup undiluted into 2 gallons of mop water to clean my floors. I sometimes add 1 squirt of Dawn Detergent if my floor is really dirty.
