The instructions for use and care are subpar, not clear enough to start working with the unit easily. I ran the first batch with the citric acid, as instructed, the instructions said don’t use the first batch, so I didn’t. The second batch I used in my coffee tasted terrible and I got sick. I had to research online and YouTube to see if there were better instructions. There are no instructions on washing the plastic bottle, but I used soap and water and rinsed very well. The third batch I ran turned out to be good and I just use vinegar to wipe out the lime residue and rinse well before distilling another batch. Overall, I love the distiller and use it several times a week, but the instructions are not good enough. The instructions are an example of a product liability law suit. The manufacturer needs to edit the instructions so each step or each category of use and care are clear and concise!
