Bests & Worsts Reviews from Amazon

This product is almost 100% Citric acid, however for the same price here on Amazon you can buy almost 10 times as much if you buy food grade (Citric acid is used for lots of things including cooking.) Two tablespoons are about the right amount for each cleaning cycle. Citric Acid - 1 lb., (Frontier) Citric Acid, priced per pound Citric Acid 4 Lb tub Citric Acid (Lemon Salt) 5 Pounds Bulk Citric Acid 1 Lb tub On the other hand, white vinegar dissolves all the lime, scale, etc. It's cheap, easy, just a little stinky and takes a little longer. This is how we've been cleaning our Zojirushi electric pots for the past 20 years. 1) Heat up the vinegar to ~150f or so (in the dispensing pot or separately) then pour in. I use a 4 cup pyrex cup in the microwave. 1.5 (Optional)I add a large mason jar in the middle to displace the vinegar so I get a higher level with less vinegar (Think of how sitting in a bathtub causes the water to rise) 2) Leave overnight 3) Rinse out thoroughly. We save the vinegar for use over and over. If you've found this review helpful, please let me know!
