Once you start using our Aromatic Cleaner you will be hooked. When that bottle starts getting empty you no longer need to panic. Each bottle of our Aromatic Cleaner Concentrate will yield one bottle of Cleaner for each ounce of Concentrate. Using our Concentrate is less expensive and additionally enables you to re-use bottles, reduce packaging waste and shipping. Use 1 oz of Cleaner Concentrate per 16oz bottle; fill with distilled water and voila!
