"Pot Cleaner"
Works great. Takes out all the deposits and gunk from the bottom. Easy to use, too.

"pot cleaner"
This product is a ripoff. Each bag of this product can only clean a one qt. pot. A 3 qt. pot requires 3 bags, which amounts to $6 bucks per cleaning. You don't find this out until you get the product and read the instructions.

"exceeded expectations"
I've had my Zojirushi hot water pot for many years. I've rinsed and tried to clean it periodically but over time the hard water residue and scaling really built up to a disgusting level.

My boyfriend got these powdered packs for me to try, I was a bit skeptical that they could do too much. But I followed the instructions written on the package and was amazed when my hot water pot came out clean as can be! It looks practically new again on the inside and I couldn't be happier. I highly recommend this product for anyone who owns a hot water pot and I will be ordering more for the next time I need to clean mine again.

"worked like a charm"
worked on my zojirushi hot water dispenser like a charm. After about one year of use, my zojirushi electric water dispenser was covered by hard calcified deposits. I tried to scrub it off, but it was so calcified nothing would come off. Then I got these, and I couldn't be happier with how easy and effective this product is, all it took was 15 minutes, and it disolved the deposits without harming my electric pot.

"Work like a charm"
I would recommend it to everyone who uses the hot water dispenser. It's very easy to use. Even if you don't see any scald build up, give it a try and you will not believe what is there. You will need one package per one liter size of pot. I only has the stubborn scald at the bottom of the pot so I figure I can put one liter of water just to cover the problem area and only use one package of powder. After the cleansing process is done, the bottom of the pot is cleaned just like the first day I got them. I then spot the ring where the water level was and realized how dirty the rest of the pot actually is. Invisible scald, I would call them. Anyway, I ended up using the rest of cleansing powder for the second cleansing batch. I'm using the pot to boil water for the baby formular. It's important that it's kept clean. This product delivers the result I hope for.
