This is pretty much the cleaner I use for everything. It works great, smells great, is so simple and super cheap.
Before you can make your spray cleaner you'll need to put a gallon of cheap white vinegar in a glass jar and add citrus peels to it, I save my citrus peels in the freezer for this purpose. I let this sit in my pantry for at least a week before using (though longer is nicer). Sometimes I strain it, sometimes I don't, I haven't found that it really matters. You can certainly make less than a gallon, I just prefer to make a gallon at a time so I always have it on hand.
Now to make the spray cleaner I add about an inch of this citrus infused vinegar to a large spray bottle (the kind you kind find in the garden dept. called plant sprayers)
Fill the bottle the rest of the way with water and add some essential oils.
