Owning your own steam water distiller is an expensive way to keep all the distilled water you need on hand for drinking and using in your appliances, such as your iron. It does require a thorough cleaning each week to assure that the distilled water you are making is clean of deposits.
Step 1 - Clean the Lid
If your distiller has a removable lid, take it off and sit it in the sink with hot water and 1/4 cup of white vinegar. If your lid is attached, make the solution in the sink and scrub the lid with a scrub brush by just holding the steamer over the sink, rinse and dry with a cloth. If you have a vent on your distiller lid, be sure to clean them thoroughly as well. When your lid is clean, you can then move on to the distiller chamber.
Step 2 - Cleaning the Chamber
Mix 1/2 vinegar to 1/2 water in the chamber. You want to add enough to cover where the mineral deposits have made a line. Have enough of the mixture to go above the line by 2 inches. The vinegar and water mixture will loosen the scale and mineral deposits for easy removal. Allow it to sit overnight, or 12 hours. When time is up, rinse well and let air dry. Reassemble your distiller and you're ready to make healthy distilled water.
