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.

I know of some people who like to fill a spray bottle with a similar solution, leaving an inch of room at the top. They will then pour peroxide and cap off the bottle. Peroxide is really good about killing germs on surfaces as well as providing extra cleaning/scrubbing power. Peroxide begins to transform into water when exposed to direct sunlight so you have about an hour to use the solution, without pouring more peroxide in the bottle.
