I have been using this for years now and love it....

Best $5.00 spent!
Eucalyptus - 100% Pure Therapeutic Grade Essential Oil - 10ml from ebay!
And reusing an empty febreze bottle (any spray bottle will work)
You can also add any other essential oil fragrances that you would like

Bet you didn't know all the wonderful uses of eucalyptus oil:

+ Odors/pest repellent
Add three drops of eucalyptus oil to a spray-bottle filled with warm water and shake well before each use to create a deodorizing/bacteria killing spray that doubles as a pest repellent (can even be used on plants).

+ Degreaser/Stain Remover
A few drops of pure eucalyptus oil will remove sticky residue (like chewing gum, sticker/decal) from surfaces (even glass, stainless steel and vehicles) and take grease, oil, paint and ink out of clothes, carpets and furniture

+ Cleaner
Bathroom: Mixing 1.6 ounces of eucalyptus oil in a quart of water creates a fresh-smelling disinfectant, mould and mildew remover and prevent re occurrence for cleaning toilets, tubs and sinks

Laundry: Add 1-2 teaspoonfuls of eucalyptus oil to your load of washing for a fresh scent along with the anti-microbial benefits

+ Air Freshener
At home: A few drops on your ducted heating or cooling air intake will freshen your house and help remove stale odors and bacteria from the ducting

In the car: add a few drops to you old hanging car freshener (never buy car fresheners again)

Not to mention that while using it as a spray to deodorize rooms and repel bugs and kill bacteria....eucalyptus is also a natural decongestant so for all of us with allergies can hopefully breath easier as well.

AND THE LIST GOES ON!
Best part is, a little bit goes a long way!
