Porcelain and Tile Green Cleaning Recipes

Baking Soda and Water: Dust surfaces with baking soda, then scrub with a moist sponge or cloth. If you have tougher grime, sprinkle on some kosher salt, and work up some elbow grease.
Lemon Juice or Vinegar: Got stains, mildew or grease streaks? Spray or douse with lemon juice or vinegar. Let sit a few minutes, then scrub with a stiff brush.
Disinfectant: Instead of bleach, make your own disinfectant by mixing 2 cups of water, 3 tablespoons of liquid soap and 20 to 30 drops of tea tree oil.
