Use boiling water and two teabags to clean hardwood floors. The tannic acid in tea creates a beautiful shine for hardwood floors. 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. This site also has other floor cleaning tips & how to minimize scratches on wood floors.
