Mix 2 teaspoons borax, 4 tablespoons vinegar and 3 cups hot water. For stronger cleaning power add 1/4 teaspoon liquid castile soap. Wipe on with dampened cloth or use non-aerosol spray bottle. (This is not an antibacterial formula. The average kitchen or bathroom does not require antibacterial cleaners.)
To disinfect kitchen sponges, put them in the dishwasher when running a load.
