4LB Citric Acid Powder Cleaning for Water Distillers - Bulk 4 LBS Universal Descaler for Distilling Machines, Kettles & More - Remove Limescale & Mineral Buildup - For Waterwise & Other Distillers

Works very well with our hard water here in Arizona.

Works great. We have used this product before and will continue to do so.

We use a distillation for all our water. We have very hard water and scale can build up fast. Every few months we use this to keep clean and shinny If we let it build up, it will break the machine. So, this saves us a lot more than it costs.

Use this for my water distiller works great

This will clean your distilled water maker very well. The directions say to leave it the cleaner/water standing overnight (paraphrasing) but I've found that if you put boiling water and the cleaner into the machine and use a scrub brush it will clean it just as well and much faster. Always add the cleaner to the water, but never the water to the cleaner. I would also use it in a well ventilated area as you don't want to inhale any of the dust of the crystals or any gas that is created when it comes in contact with the water. I use distilled water for my C-PAP machine and in humidifiers throughout my house, especially in the winter.
