Citrus essential oils have a natural antiseptic property, which explains why cleaning materials based on orange, for example, started to come onto the market a decade or so ago. They smell a lot nicer than some of the things used in other cleaning products, as well, and it's very unlikely that you will come to any harm using them (unless you're allergic, of course), which can't be said about certain chemicals commonly used around the home.
I came across this article which contains 3 recipes for household use of citrus essential oils, and I thought I would pass it on. You'll find it here:

So far as using citrus oils on the body goes, it's worth pointing out that they often cause photosensitivity – so it's best to avoid spending much time in strong sunlight – or to cover the area you've treated if you intend to do so. Of course, the sun is becoming weaker now in the Northern hemisphere, unless you live quite close to the equator, but it's something to bear in mind for the summer time.
I agree with you. This is the reason we add lemon or orange juice to home made face packs.
