ZojirushiCitric Acid Cleaner for Electric Water Boilers, 4 Packets (1oz/30g each), White

This stuff works! I hadn't cleaned by water heater in a long time - a bit more than a year - and tried some of the homemade remedies that I saw online (vinegar, lemon juice, etc.) and those methods just didn't really work in getting rid of any of the scaling on the pot.So I bit the bullet and spent the money for this. It feels like it's more expensive than it needs to be, but the fact that one application worked perfectly in taking off ALL the scaling and cleaning the pot, I'm going to say it was worth it. But since the de-scaling really should be done every 3 or 4 months and not once every 15 or so months, it's a pricey bit of maintenance.So, I gave it three stars for value simply because it will become a costly maintenance device. And maybe some of those homemade remedies would work if I did them every months instead of waiting for the amount of scaling I had built up, and then use these just once in a while to give it a serious cleaning.I rated it five stars on taste not because I tasted it - I didn't, and you shouldn't: it's not food - but because I didn't want the taste rating to affect its overall rating.Does it do its job? Heck yes! Supremely well.Is it a good value for the money? That might be up to you to decide.

Great cleaner for the water machine

Zojirushi, in general, is a brand synonymous with high-quality, well-thought out, practical, incredible household products. I use this cleaner with my 3.0 Liter hot-water boiler and it is one of my favorite appliances to use in our kitchen. This cleaner keeps the boiler clean and de-scaled when used on a regular a basis.It’s recommended to use this every few months to ensure that the inside of your hot water boiler is descaled properly from hard materials present in your water.I live in a part of Texas where we have harder water, and even with an Aquasana filter, sediment can build up inside the hot water boiler over time.I would recommend checking the inside of your hot-water boiler every few weeks to months to check if you have any white, filmy residue build-up around the perimeter or bottom of your Zojirushi hot-water boiler. If you do, use this pocket and fill up the hot water boiler with warm water, let the cleaning function work it’s magic by holding down the proper button on your model, and then voila! Insides cleaned!After using cleaner, I always pour out the mixture into the sink, then rinse the insides again a few times to ensure it is completely descaled. Sometimes, though, if there has been significant buildup after nor cleaning for a long time, you may still have to scrub the inside of your boiler to get all buildup out. This is not a knock on the product, just the fact that a ton of buildup needs more than a routine maintenance cleaning to get it completely cleaned out.Lastly, after cleaning and rinsing in the sink, be sure to fill up the container and drain out probably another full tank of water through the spout to SME sure all the chemicals have been flushed out properly. You don’t want to taste the cleaning solution in your coffee or tea! 😖I would highly recommend getting this to keep your product clean and humming on all cylinders!

Works well.Got most of the grime that was inside the water boiler.Did 2 extra flushes after just to be sure. Water tasted normal, no issues with smell or taste.

Item received is the same as pictured.The product works well at removing mineral deposit build up on the interior of my electric kettle.After an initial boil with the citric acid cleaner, I hand wash the kettle to ensure removal of any residual powder, rinse it, and boil with filtered water to finish.I recommend this product to friends and family as it is a good value and easy to use.

Easy to use, clear instructions and it works

Really cleans and increases flow of tank and water!

This product works great! I got myself in trouble when I used a cleaning agent intended for Keurig that I have at home to descale my zojirushi kettle. The agent worked well for my coffee machine but for some reason it hardened the scale in my kettle, which then clogged the dispenser. When I pressed the dispense button, the motor makes a loud noise but would not dispense water. I was afraid that I had broken the kettle. I ordered this product and run a deep clean cycle and an hour and half later, my kettle worked again, with the interior completely scale free. Would definitely recommend it! Worth every penny.
