Mixing 20ml pure castile soap with 200ml distilled water in an amber glass spray bottle creates a streak-free degreaser suitable for butcher block and quartz.

Why Hard Water Requires Distilled Dilution

Calcium ions in hard municipal tap water react with liquid soap to form insoluble calcium stearate (soap scum). Always dilute pure soap with distilled water.
