How do I clean air freshener residue off the floor?

If it is residue from oil air freshens this is an excellent guide:

Wipe it off with rubbing alcohol.

I would think a good grease cutting detergent like Dawn would work.

You can make your own frebeze of sorts by adding 1/4 of fabric softener to a spray bottle and top off with water. This will give a nice scent but not leave the oily residue like the original because it is only fabric softener.

Another nice quality is that is costs about 1/10 of what you pay for a bottle of Frebeze.

If you have a tile floor, mop with this

1 cup baking soda

1 cup white cleaning vinegar

1 Tbsp blue Dawn

2 gallons hot water (I boil about 1/3 of mine)
