Great all-natural cleaner. I personally like the peppermint and almond castile scents. Use paper towels, newspapers or even old t-shirts. Don't worry, after the solution dries it doesn't smell like vinegar. Great for stainless steel, glass, counters, etc :-)
Mix 1 teaspoon of tea tree oil per 1 cup of water. Spray onto the surface with mold or Mildew and allow to dry, do not rinse. This will kill the mold spores without creating harsh chemical fumes as other cleaners, such as bleach, would.
