Dish detergent is a mild degreaser that leaves behind no residue (perfect for vinyl floors). Run one gallon of lukewarm water into your cleaning bucket, then add 1/2 cup of rubbing alcohol and 1/2 cup of vinegar. Finally, stir in two to three drops of liquid dish detergent (a little dish soap goes a long way). Stir with your mop, and clean your floor as usual. This works great as a daily or bi-weekly cleaner and disinfectant, keeping your floor shiny and bacteria free.
