Kill mold with tea tree oil! Mix 1 teaspoon of tea tree oil per 1 cup of water. Spray onto the surface with mold 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.
Use boiling water and two teabags to clean hardwood floors. The tannic acid in tea creates a beautiful shine. Let two teabags steep in the boiling water for a few minutes. Pour the tea into a bucket. Take a soft cloth and wring it out in the tea. The cloth merely needs to be damp, not soaked. This will enable the floor to dry quickly. Wash the floor and be ready to be amazed by the sheen... and no sticky or oily residue!
To clean a cast iron skillet, scrub it with coarse salt and a soft sponge. The salt, a natural abrasive, absorbs oil and lifts away bits of food while preserving the pans seasoning. Rinse away salt and wipe dry.
