Collect orange peels until you can fill up a 1 liter glass jar. You could keep them in the freezer until you have enough. Stuff them in the jar, fill it up with vinegar, submerging the peels in it. Leave it for 10 days, strain and use the liquid to clean and desinfect any surface.
Simple to make, economic, natural and has a nice smell.
